Caregiver Perspectives on Barriers and Facilitators to Timely Well-Child Visits for Black Infants.

OBJECTIVES: Missed infant well-child visits (WCV) result in lost opportunities for critical preventive care. Black infants consistently receive less WCV care than other racial groups. We sought to understand barriers and facilitators to timely infant WCV for Black families in the context of COVID-19. METHODS: We conducted 21 semi-structured interviews with caregivers of Medicaid-insured Black children aged 15- to 24-months who attended six or fewer of eight recommended well-child visits within the first 15 months of life. Interviews focused on WCV value, barriers, and facilitators. After developing our initial coding structure through rapid qualitative analysis, we inductively derived the final codebook and themes through line-by-line content analysis. RESULTS: Caregivers attended a mean of 3.53 of eight infant visits. Structural (e.g., transportation) and psychological (e.g., maternal depression) barriers delayed Black infant WCV. Families most frequently valued monitoring development and addressing concerns. Caregivers perceived visits as less urgent when infants seemed healthy or more recently avoided visits due to fears around COVID-19. Long waits and feeling rushed/dismissed were linked to WCV delays; positive provider relationships encouraged WCV attendance. Most caregivers reported reluctance to vaccinate. Vaccine hesitancy contributed to delayed infant WCV. CONCLUSIONS: Caregivers described several factors that impacted WCV attendance for Black infants. Persistent structural and psychological barriers are compounded by perceptions that caregiver time is not respected and by notable vaccine hesitancy. To address these barriers, well-care can meet Black families in their communities, better address caregiver wellbeing, more efficiently use caregiver and provider time, and cultivate partnerships with Black caregivers.

A method for sampling parasitized Drosophila suzukii (Diptera: Drosophilidae) puparia from soil.

Methods to measure the diversity and biological control impact of parasitoids for the control of spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) are being developed in support of biological control programs around the world. Existing methods to determine parasitism levels and parasitoid species composition focus on sampling D. suzukii within fresh and rotting fruit. However, many D. suzukii pupate in the soil or in dropped fruit, where additional parasitism could occur and where their parasitoids are thought to overwinter. Here we introduce a method for extracting parasitized D. suzukii puparia from the soil through a sieve and flotation system, allowing for effective collection of puparia, from which parasitoids can then be reared. Although the method considerably underestimates the absolute number of puparia in soil samples, it nonetheless yields a high number of puparia relative to sampling effort and provides a robust estimate of the relative abundance of puparia among samples. Using this method, we confirmed that at least 5 species of parasitoids, including some that have rarely been detected in past studies, overwinter in their immature stages inside D. suzukii puparia in south coastal British Columbia, Canada. The ability to sample puparia from the soil will lead to a more comprehensive view of both D. suzukii and parasitoid abundance throughout the season, help confirm parasitoid establishment following intentional releases, and provide a way to measure the diversity of parasitoid species and potential interactions among parasitoids (e.g., hyper- or klepto-parasitism) that may often occur on the soil surface.

Cognitive behavioural therapy and medication for treatment of adolescent depression: a network meta-analysis.

BACKGROUND: Cognitive behavioural therapy (CBT) and medication are widely accepted and useful interventions for individuals with depression. However, a gap remains in our current understanding of how CBT directly benefits adolescents with depression. AIMS: The purpose of this study was to examine the short- and long-term effectiveness of CBT only, CBT+Medication, or Medication alone in reducing the duration of major depressive episodes, lessening internalizing and externalizing symptoms and improving global functioning. METHODS: Data were extracted from 14 unique studies with a total of 35 comparisons. Network meta-analysis was conducted and p-scores, a measure of the extent of certainty that one treatment is better than another, were used to rank treatments. RESULTS: There was no significant difference between any two treatments for depression, nor internalizing or externalizing symptoms. For global functioning, CBT had significantly greater effect at the longest follow-up than CBT+Medication. CBT+Medication had the highest p-score for depression, short- and long-term effects, and internalizing and externalizing symptoms long-term effects. No indication of publication bias was found. CONCLUSIONS: Neither modality, CBT nor medication, is superior for treating adolescent depression. However, CBT was superior in improving global functioning, which is essential for meeting developmental goals.

Cross-Sector Intervention Strategies to Target Childhood Food Insecurity in North Carolina.

BACKGROUND: Childhood food insecurity increased considerably during the COVID-19 pandemic and is associated with compromised health. Health care systems are increasingly prioritizing food insecurity interventions to improve health, but it is unclear how health systems collaborate with other sectors that are addressing food insecurity. In this study, we aimed to evaluate existing collaborations and explore opportunities for further cross-sector engagement. METHODS: From December 2020 to March 2021, we conducted semi-structured interviews (N = 34) with informants involved in increasing child food access in North Carolina. Our informants represented different sectors, including community (e.g., food pantry), education (e.g., school lunch program), and government (e.g., Supplemental Nutrition Assistance Program). Rapid qualitative analysis was used to interpret the results and identify themes. RESULTS: Informants rarely mentioned the health care sector as a source of referrals or as a collaborator. Barriers limiting access to food insecurity programs were exacerbated by the COVID-19 pandemic, including lack of transportation, stigma deterring use, limited food choice, and burdensome enrollment processes. Stakeholders recommended mitigating barriers through the expansion of food delivery, colocalization of assistance programs in schools and health care settings, increased food choice, and supporting cross-program enrollment mechanisms. LIMITATIONS: The majority of the stakeholders represented programs from five counties in central North Carolina, with only a few representing statewide initiatives. CONCLUSIONS: The COVID-19 pandemic both highlighted the fragmented system of food insecurity organizations and accelerated development of cross-sector collaborations to reduce access barriers. Health care systems are siloed from school and community efforts but have the opportunity to leverage ongoing innovative policy initiatives to construct novel cross-sector models. Such models can better link food insecurity screening with community-based solutions to address family-level food access barriers.

Identifying Individuals With Intellectual Disability Within a Population Study.

BACKGROUND: Much remains unknown about the longitudinal health and well-being of individuals with intellectual disability (ID); thus, new methods to identify those with ID within nationally representative population studies are critical for harnessing these data sets to generate new knowledge. OBJECTIVE: Our objective was to describe the development of a new method for identifying individuals with ID within large, population-level studies not targeted on ID. METHODS: We used a secondary analysis of the de-identified, restricted-use National Longitudinal Study of Adolescent to Adult Health (Add Health) database representing 20,745 adolescents to develop a method for identifying individuals who meet the criteria of ID. The three criteria of ID (intellectual functioning, adaptive functioning, and disability originating during the developmental period) were derived from the definitions of ID used by the American Psychiatric Association and the American Association on Intellectual and Developmental Disabilities. The ID Indicator was developed from the variables indicative of intellectual and adaptive functioning limitations included in the Add Health database from Waves I to III. RESULTS: This method identified 441 adolescents who met criteria of ID and had sampling weights. At Wave I, the mean age of this subsample of adolescents with ID was 16.1 years. About half of the adolescents were male and from minority racial groups. Their parents were predominately female, were married, had less than a high school education, and had a median age of 41.62 years. The adolescents' mean maximum abridged Peabody Picture Vocabulary Test standardized score was 69.6, and all demonstrated at least one adaptive functioning limitation. DISCUSSION: This study demonstrates the development of a data-driven method to identify individuals with ID using commonly available data elements in nationally representative population data sets. By utilizing this method, researchers can leverage existing rich data sets holding potential for answering research questions, guiding policy, and informing interventions to improve the health of the ID population.

High-through identification of T cell-specific phage-exposed mimotopes using PBMCs from tegumentary leishmaniasis patients and their use as vaccine candidates against Leishmania amazonensis infection.

In the current study, phage-exposed mimotopes as targets against tegumentary leishmaniasis (TL) were selected by means of bio-panning cycles employing sera of TL patients and healthy subjects, besides the immune stimulation of peripheral blood mononuclear cells (PBMCs) collected from untreated and treated TL patients and healthy subjects. The clones were evaluated regarding their specific interferon-γ (IFN-γ) and interleukin-4 (IL-4) production in the in vitro cultures, and selectivity and specificity values were calculated, and those presenting the best results were selected for the in vivo experiments. Two clones, namely A4 and A8, were identified and used in immunization protocols from BALB/c mice to protect against Leishmania amazonensis infection. Results showed a polarized Th1 response generated after vaccination, being based on significantly higher levels of IFN-γ, IL-2, IL-12, tumour necrosis factor-α (TNF-α) and granulocyte-macrophage colony-stimulating factor (GM-CSF); which were associated with lower production of specific IL-4, IL-10 and immunoglobulin G1 (IgG1) antibodies. Vaccinated mice presented significant reductions in the parasite load in the infected tissue and distinct organs, when compared with controls. In conclusion, we presented a strategy to identify new mimotopes able to induce Th1 response in PBMCs from TL patients and healthy subjects, and that were successfully used to protect against L. amazonensis infection.

Health Care Transition for Adolescent and Young Adults with Intellectual Disability: Views from the Parents.

PURPOSE: This study explored the health care transition (HCT) experiences of parents of adolescents and young adults (AYAs) with intellectual disability (ID), 18-33 years of age, including barriers and facilitators to the AYA's transition to adulthood within and between the medical, educational, community, and vocational systems. DESIGN AND METHODS: A qualitative descriptive design with semi-structured individual interviews with 16 parent participants was used. Purposive sampling of parents was utilized with variation on race/ethnicity and AYA age, stage in transition, and condition. This study was conducted through a major medical center in the southeast United States. Content analysis was utilized. RESULTS: Three overarching themes represented the factors and essence of supporting AYAs with ID transition to adulthood. Inefficient and siloed systems illuminated barriers families are commonly experiencing within and between the medical, educational, community, and vocational systems. 'Left out here floundering' in adulthood, described the continued inadequacy of resources within each of these systems and parent's having to find available resources themselves. Hope despite uncertainty, included the perceived costs and benefits of their AYA's disability and the value of parent peer support in providing key knowledge of resources, strategies, and perspectives. CONCLUSIONS: Our findings illuminate the need for improved infrastructure to provide effective HCT and partnerships to help integrate HCT support within other life course systems. Results support the rationale for non-categorical HCT-focused approach. PRACTICE IMPLICATIONS: A parent peer coach-facilitated intervention offers promise for bridging the gap between systems and meeting family needs.

Psychometric Properties and Factor Structure of the Center for Epidemiologic Studies Depression Scale in a National Sample of Arab Adolescents.

Having valid, reliable, and culturally adapted tools to screen for adolescent depression is a crucial concern for mental health care professionals who promote preventive care. To this aim, this study tested the psychometric properties and factor structure of the Center for Epidemiologic Studies Depression (CES-D) Scale among Arab adolescents. A nationally representative sample of 3,292 Jordanian adolescents aged 13-17 completed the CES-D 20-item scale. A principal axis factoring with a varimax rotation was used to identify the factor structure of the scale on a half of the sample (n1 = 1,655), followed by a confirmatory factor analysis to assess the fitness of the factor structure to the other half of the sample (n2 = 1,637) on a variety of model-fit indices. Findings did not support the original four-factor structure. The results indicated that two factors provide a reasonably better fit: Factor 1 combined items on depressed affect, somatic complaints and interpersonal problems, and Factor 2 consisted of the remaining four positive affect items. The modified model showed high internal reliability and excellent construct validity. The results revealed that depression construct among Arab adolescents, as measured by the CES-D, differs from that in other ethnic groups. Nurses and other health professionals need to closely examine the different presentation of depressive symptoms across racial and ethnic groups to avoid diagnostic errors, inappropriate management, and poor compliance.

Diagnostic application of recombinant Leishmania proteins and evaluation of their in vitro immunogenicity after stimulation of immune cells collected from tegumentary leishmaniasis patients and healthy individuals.

The present study evaluated the cytokine profile in PBMC supernatants and the humoral response in mucosal leishmaniasis (ML) patients and in healthy subjects living in an endemic area. Four proteins, which had previously proven to be antigenic in the human disease, were tested: LiHyM, enolase, eukaryotic initiation factor 5a, and Beta-tubulin. Results showed that all of the proteins stimulated human cells with higher IFN-γ and lower IL-4 and IL-10 levels. The analysis of antibody isotypes correlated with cell response, since the IgG2 production was higher than IgG1 in both groups. By contrast, a Th2 response was found when an antigenic Leishmania extract was used. Serological analyses revealed high sensitivity and specificity values for the serodiagnosis of the disease, when compared to the data obtained using the antigenic preparation. In conclusion, this study presents new candidates to be evaluated as biomarkers in tegumentary leishmaniasis.

Mandated data archiving greatly improves access to research data.

The data underlying scientific papers should be accessible to researchers both now and in the future, but how best can we ensure that these data are available? Here we examine the effectiveness of four approaches to data archiving: no stated archiving policy, recommending (but not requiring) archiving, and two versions of mandating data deposition at acceptance. We control for differences between data types by trying to obtain data from papers that use a single, widespread population genetic analysis, structure. At one extreme, we found that mandated data archiving policies that require the inclusion of a data availability statement in the manuscript improve the odds of finding the data online almost 1000-fold compared to having no policy. However, archiving rates at journals with less stringent policies were only very slightly higher than those with no policy at all. We also assessed the effectiveness of asking for data directly from authors and obtained over half of the requested datasets, albeit with ∼8 d delay and some disagreement with authors. Given the long-term benefits of data accessibility to the academic community, we believe that journal-based mandatory data archiving policies and mandatory data availability statements should be more widely adopted.

Remodeling Broken Systems: Addressing the National Emergency in Child and Adolescent Mental Health.

A national emergency in child and adolescent mental health was declared in the United States in 2021 in the wake of the COVID-19 pandemic. This Open Forum discusses potential solutions to better support child and adolescent mental health by improving or expanding school-based mental health services, child psychiatry access programs, virtual mental health services, and new models of care (e.g., integrated youth services hubs and crisis stabilization units). The success of such programs is dependent on stable funding, strong leadership and accountability, robust and well-trained workforces, systems integration, and attention to health equity.

Building Equitable Mental Health Care for Latino Children: Perspectives from Providers and Communities.

BACKGROUND: The current pediatric mental health crisis has disproportionately impacted Latino youth in the United States (US), as demonstrated by their elevated risks of depression, substance use disorder, and anxiety. Despite this, research suggests Latino youth receive inequitable mental health services. OBJECTIVE: To understand best practices, challenges, and priorities in providing accessible and equitable mental health care for Latino youth from the perspectives of front-line mental health providers and Latino community members. METHODS: A bicultural, bilingual researcher conducted semi-structured interviews with 20 participants with expertise in Latino mental health. Topics included barriers and facilitators to mental health care access and cultural tailoring of treatment for Latino youth. Rapid qualitative analysis was used to identify themes. RESULTS: Four themes were identified: (1) Navigating immigration concerns and acculturation, practitioners should consider immigration-related concerns and be trained to address acculturation-related stressors respectfully; (2) Adapting to the cultural needs and strengths of the communities, cultural humility education can allow providers to engage with both the strengths and needs of Latino families; (3) Engaging Latino caregivers as partners, it is critical to engage with Latino caregivers' cultural perspectives on parenting and mental health collaboratively; and (4) Addressing systemic barriers to promote access, providers must recognize and attempt to alleviate the systemic barriers that limit families from seeking care. CONCLUSIONS: Participants identified several practical strategies to improve the provision of mental health services for Latino children. Future directions, policy and practice implications, and limitations are discussed.

Recommendations for utilizing and reporting population genetic analyses: the reproducibility of genetic clustering using the program STRUCTURE.

Reproducibility is the benchmark for results and conclusions drawn from scientific studies, but systematic studies on the reproducibility of scientific results are surprisingly rare. Moreover, many modern statistical methods make use of 'random walk' model fitting procedures, and these are inherently stochastic in their output. Does the combination of these statistical procedures and current standards of data archiving and method reporting permit the reproduction of the authors' results? To test this, we reanalysed data sets gathered from papers using the software package STRUCTURE to identify genetically similar clusters of individuals. We find that reproducing structure results can be difficult despite the straightforward requirements of the program. Our results indicate that 30% of analyses were unable to reproduce the same number of population clusters. To improve this, we make recommendations for future use of the software and for reporting STRUCTURE analyses and results in published works.

Comparison of three intraoperative patient warming systems.

The purpose of this randomized clinical trial was to compare the efficacy of three patient warming devices (i.e., circulating water blanket, forced-air, and warming panels) used either alone or in combination on patients undergoing surgeries lasting >60 min. In total, 238 dogs were included and divided into either the celiotomy or nonceliotomy group. Dogs in each group were further divided into one of three subgroups. Dogs in subgroup 1 (n=39) were placed on a circulating water blanket with a forced-air warming blanket placed over the trunk. Subgroup 2 dogs (n=40) were placed on a forced-air warming blanket only. Subgroup 3 dogs (n=40) were placed on warming panels. Significant temperature drops occurred from time of induction (38.1°C±0.64°C) to the start of surgical procedures (36.7°C±0.95°C). Although body temperature was maintained once the warming units were started in all groups, there were significant differences in temperatures for the type of surgical procedures (i.e., celiotomies versus nonceliotomies) performed over time except for subgroup 3. The warming panels and forced-air devices were equally effective in preserving body temperature in anesthetized patients.

Influence of provider type on chronic pain prescribing patterns A systematic review.

BACKGROUND: Chronic pain affects 100 million Americans and is most often treated in primary care, where the health care provider shortage remains a challenge. Nurse practitioners (NPs) represent a growing solution, yet their patterns of chronic pain management are understudied. Additionally, prescriptive authority limitations in many states limit NPs from prescribing opioids and often exist due to concerns of NP-driven opioid overprescribing. Little evidence on NP pain management prescribing patterns exists to address these issues. OBJECTIVE: Systematic review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, to examine opioid and nonopioid prescribing patterns of physicians, NPs, and physician assistants (PAs) in primary care. Eligible studies scored ≥60% on the Joanna Briggs Institute Critical Appraisal checklist. DATA SOURCES: Searches within PubMed, Embase, CINAHL, and Web of Science. CONCLUSIONS: Three themes were elucidated: 1) opioid prescribing in primary care, 2) similarities and differences in opioid prescribing by provider type, and 3) nonopioid pain management strategies. All provider groups had similar opioid prescribing patterns, although NPs and PAs may be slightly less likely to prescribe opioids than physicians. Although some studies suggested that NPs/PAs had higher opioid prescribing rates compared with physicians, methodological flaws may undermine these conclusions. Evidence is also lacking on nonopioid prescribing patterns across disciplines. IMPLICATIONS FOR PRACTICE: Nurse practitioner/PA prescriptive authority limitations may not be as effective of a solution for addressing opioid overprescribing as transdisciplinary interventions targeting the highest subset of opioid prescribers. Future research should examine prescribing patterns of nonopioid, including nonpharmacologic, therapies.

Qualitative Perceptions of an Anticipated Fresh Food Prescription Program.

Objective: Food insecurity (FI) is a growing public health problem. Produce prescriptions are known to improve healthy eating and decrease FI; however, few studies have incorporated community voice prior to its implementation. In this study, we aimed to elicit perspectives of individuals at risk for FI and the potential impact of a fresh food prescription (FFRx) program. Methods: We conducted this qualitative descriptive study through an academic medical center in collaboration with community partners. We conducted focus groups involving Latinx (N = 16) and African-American (N = 8) adults in community settings. Data were interpreted using an inductive thematic analysis. Results: Three overarching themes emerged: (1) fresh food accessibility was limited by cost, household size, and transportation but enhanced by food pantries, budgeting, and education; (2) cooking behaviors were curbed by time constraints and unfamiliarity but propagated by passion, traditions, and communal practices; and (3) health and wellness deterrents included unhealthy diets driven by cultural and familial norms; however, weight loss and awareness of comorbidities were positive motivators. Participants shared their preference for local produce and cooking classes as components of a FFRx program while raising concerns about low participation due to the stigma of receiving aid. Conclusions: Our findings illuminated interest in engaging in a FFRx program and learning ways to prepare healthy foods. A program distributing fresh produce and healthy lifestyle education could close gaps identified in African-American and Latinx communities at risk for FI.

Inequities in Receipt of the North Carolina Medicaid Waiver Among Individuals with Intellectual Disability or Autism Spectrum Disorder.

OBJECTIVE: We examined characteristics associated with receiving the North Carolina Home and Community-Based Services Waiver for intellectual and developmental disabilities (I/DDs) and its association with emergency department (ED) utilization. METHOD: Through analysis of the North Carolina 2017 to 2018 Medicaid claims and enrollment data, we examined characteristics (age, sex, race and ethnicity, geography, diagnosis (intellectual disability [ID] with or without autism spectrum disorders or autism spectrum disorder without ID) associated with receiving the NC I/DD Waiver and the association of this Wavier with ED utilization. We identified patients with at least 1 International Classification of Diseases-10-CM diagnosis code for an ID or autism spectrum disorder. We excluded patients with missing county information and whose enrollment in the NC I/DD Waiver program began after October 1, 2017. RESULTS: Only 22% of 53,531 individuals with I/DD in North Carolina received the Waiver. Non-Hispanic Blacks and Hispanic individuals were less likely to receive the Waiver than non-Hispanic White individuals. Adults (>21 years old), men, and urban residents were more likely to receive the Waiver. Individuals who received the Waiver were 31% less likely to use the ED. CONCLUSION: Innovative strategies are needed to provide equitable access to the NC I/DD Waiver and provide services to the 14,000 people with I/DD currently waiting to receive the Waiver. Through the Waiver, those with I/DD can access preventative and therapeutic outpatient services and decrease their need for ED care. These findings highlight the need for policy reform to address inequities in access to the Waiver for individuals with I/DD.

Adventive Larval Parasitoids Reconstruct Their Close Association with Spotted-Wing Drosophila in the Invaded North American Range.

Two species of larval parasitoids of the globally invasive fruit pest, Drosophila suzukii (Diptera: Drosophilidae), Leptopilina japonica, and Ganaspis brasiliensis (both Hymenoptera: Figitidae), were detected in British Columbia, Canada in 2016 and 2019, respectively. Both are presumed to have been unintentionally introduced from Asia; however, the extent of their establishment across different habitats with diverse host plants used by D. suzukii was unclear. In addition, there was no knowledge of the temporal dynamics of parasitism of D. suzukii by these two parasitoids. To address these gaps, we repeatedly sampled the fruits of known host plants of D. suzukii over the entire 2020 growing season in British Columbia. We documented the presence of L. japonica and G. brasiliensis and estimated the apparent percentage of D. suzukii parasitized among host plant species. Across a large region of southwestern British Columbia, both L. japonica and G. brasiliensis were found to be very common across a variety of mostly unmanaged habitats over the entire course of the season (May-October) in the fruits of most host plants known to host D. suzukii larvae. Parasitism of D. suzukii was variable (0-66% percent parasitism) and appeared to be time-structured. Our study demonstrates that the close association between the two larval parasitoids and D. suzukii that exists in Asia has evidently been reconstructed in North America, resulting in the highest parasitism levels of D. suzukii yet recorded outside of its area of origin.

Racial and Ethnic Differences in Psychotropic Prescription Receipt Among Pediatric Patients Enrolled in North Carolina Medicaid.

OBJECTIVE: The authors aimed to examine racial-ethnic differences in filled psychotropic prescriptions among a pediatric Medicaid population. METHODS: This retrospective cohort study included patients ages 0-21 with at least one North Carolina Medicaid claim from October 1, 2017, through September 30, 2018 (N=983,886). The primary outcome was a filled psychotropic prescription. Separate multivariable modified Poisson regression models generated adjusted risk ratios (ARRs) and 95% confidence intervals (CIs), adjusted for patient demographic characteristics. RESULTS: Black and Hispanic patients were significantly less likely to receive any filled psychotropic prescription (ARR=0.61, 95% CI=0.60-0.62; ARR=0.29, 95% CI=0.28-0.29, respectively) compared with White and non-Hispanic patients. Furthermore, Black and Hispanic patients were less likely to receive filled prescriptions in the four included drug classes compared with White and non-Hispanic patients. CONCLUSIONS: Future studies should focus on understanding the factors contributing to racial and ethnic differences among pediatric patients receiving filled psychotropic prescriptions.

A Coordinated Sampling and Identification Methodology for Larval Parasitoids of Spotted-Wing Drosophila.

We provide recommendations for sampling and identification of introduced larval parasitoids of spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). These parasitoids are either under consideration for importation (aka classical) biological control introductions, or their adventive (presumed to have been accidentally introduced) populations have recently been discovered in North America and Europe. Within the context of the ecology of D. suzukii and its parasitoids, we discuss advantages and disadvantages of estimating larval parasitism levels using different methods, including naturally collected fruit samples and sentinel baits. For most situations, we recommend repeated sampling of naturally occurring fruit rather than using sentinel baits to monitor seasonal dynamics of host plant-Drosophila-parasitoid associations. We describe how to separate Drosophilidae puparia from host fruit material in order to accurately estimate parasitism levels and establish host-parasitoid associations. We provide instructions for identification of emerging parasitoids and include a key to the common families of parasitoids of D. suzukii. We anticipate that the guidelines for methodology and interpretation of results that we provide here will form the basis for a large, multi-research team sampling effort in the coming years to characterize the biological control and nontarget impacts of accidentally and intentionally introduced larval parasitoids of D. suzukii in several regions of the world.
