RESUMO

OBJECTIVES: To characterize the clinical presentation, possible trigger factors and seasonality of acute urticaria (AU) in children referred to the emergency department in a teaching hospital in London, United Kingdom. METHODS: This was a retrospective descriptive study. One hundred and sixty-three consecutive patients younger than 18 years with the diagnosis of AU who attended accident and emergency department from January 2018 until January 2020 at Chelsea and Westminster Hospital in London, United Kingdom, were included in the study. Descriptive statistics were performed using IBM SPSS 25. RESULTS: In total, 163 patients younger than 18 years, 82 (50.3%) boys and 81 (49.7%) girls. The median age of patients with AU was 4 years (interquartile range, 6 years). In 120 of (73.6%) 163 patients, there was no clear trigger of AU, in 17 (10.4%) of 163 patients, upper respiratory infection was considered as a potential trigger of AU, followed by food in 14 (8.6%) cases, medications in 9 (5.5%) cases, hymenoptera sting in 1 (0.6%) case, and contact urticaria 2 (1.2%) cases. Seventeen (10.4%) of the patients were admitted into the hospital as a result of their urticaria. The majority of AU urticaria cases were reported in autumn with 76 (46.6%) cases with most of AU cases occurring in November (34/163, 20.9%). CONCLUSIONS: A total of 163 cases of AU were identified between January 2018 and January 2020. A seasonal trend of AU in autumn was observed. Respiratory infections were found to be the most commonly associated potential trigger of AU cases.

RESUMO

We investigated the effect of bee species identity and harvesting methods on the chemical composition and antiradical activity of 53 honey samples, produced by six stingless bee species in western Kenya (Kakamega forest). Our results illustrate that none of the assayed parameters significantly varied between the honey samples harvested by "punching holes" (n = 25) and "squeezing" (n = 28) methods. By contrast, species identity drove significant differences in the assayed parameters. Positive correlations between the antiradical activity and the phytochemicals (phenols and flavonoids) were observed, and honeys from Liotrigona sp. exhibited the highest amounts of phenols (214 mg GAE/100 g), flavonoids (73.0 mg QE/100 g) and antiradical activity (76.2%). The physicochemical analyses confirm the need to establish separate stingless bee honey standards for moisture, free acidity, invertase, electrical conductivity, and HMF, as these parameters significantly diverged from the set limits for Apis mellifera honey.

RESUMO

Hymenoptera stinging insects are common culprits for allergic reactions. Anaphylaxis to insect stings can be life threatening and is associated with a significant risk of recurrence. Insect allergy requires referral to an allergist/immunologist for education and for diagnostic evaluation that will direct further management and treatment. Venom immunotherapy is safe and effective; it prevents sting anaphylaxis in up to 98% of patients. Potential risk factors for side effects during testing and treatment should be assessed for every patient to mitigate risk and to guide treatment recommendations and the duration of immunotherapy.

RESUMO

As a wildly used plant-derived insecticide, azadirachtin (AZA) is commonly reported as harmless to a range of beneficial insects. However, with the research on the effect of AZA against pollinators in recent years, various negative physiological effects on other Apidae species have been demonstrated. Thus to explore the safety of azadirachtin to Apis cerana cerana, the different physiological effects of sublethal concentration of azadirachtin on worker bees A.c.cerana has been studied. With the exposure of 5 mg·L-1 and 10 mg·L-1 azadirachtin for 5 d, the relative expression of Apidaecin, Abaecin and Lysosome genes in workers has decreased significantly at 1, 2,3 and 5 d, and the mRNA levels of Defensin 2 and Hymenoptaecin were also significantly inhibited by 10 mg·L-1 azadirachtin at each check point. Besides, the activity of midgut antioxidant enzymes Superoxide Dismutase (SOD) and Catalase (CAT) which are the first line of defence in antioxidant systems was not affected by AZA, the activity of Peroxidase (POD) showed a fluctuating pattern at 24 h and 48 h, while the activity of polyphenol oxidase (PPO) has significantly inhibited by AZA. However, through 16sRNA analysis it was observed that 5 mg·L-1 AZA did not affect the midgut microbiome colony composition and relative abundance, as well as its main function. Therefore, to a certain extent, azadirachtin is safe for workers, but we should pay more attention to the sublethal effect of AZA that also detrimental to the healthy development of the honeybee colony.

RESUMO

The use of nectar-producing companion plants in crops is a well-known strategy of conserving natural enemies in biological control. However, the role of floral volatiles in attracting parasitoids and effects on host location via herbivore-induced plant volatiles is poorly known. Here, we examined the role of floral volatiles from marigold (Tagetes erecta), alone or in combination with volatiles from sweet pepper plant (Capsicum annuum), in recruiting Aphidius platensis, an important parasitoid of the green peach aphid Myzus persicae. We also investigated whether marigold floral volatiles are more attractive to the parasitoid than those emitted by sweet pepper plants infested by M. persicae. Olfactometry assays indicated that floral volatiles attracted A. platensis to the marigold plant and are more attractive than sweet pepper plant volatiles. However, volatiles emitted by aphid-infested sweet pepper were as attractive to the parasitoid as those of uninfested or aphid-infested blooming marigold. The composition of volatile blends released by uninfested and aphid-infested plants differed between both blooming marigold and sweet pepper, but the parasitoid did not discriminate aphid-infested from uninfested blooming marigold. Volatile released from blooming marigold and sweet pepper shared several compounds, but that of blooming marigold contained larger amounts of fatty-acid derivatives and a different composition of terpenes. We discuss the potential implications of the aphid parasitoid attraction in a diversified crop management strategy.

RESUMO

OBJECTIVES: DNA barcoding became an effective method for the identification and monitoring of bees. However, standard primer pairs used for barcoding often result in (co-) amplification of bacterial endosymbionts of the genus Wolbachia, which are widespread among bee species. Here we designed a new primer pair and compared it with the performance of the standard Folmer-primers for a small sample set of bees representing the main taxonomic groups of bees. RESULTS: The newly designed primer pair (BeeCox1F1/BeeCox1R2) outperformed the standard barcoding primer (LCO1490/HCO2198). By generating barcodes for a small test set of bees we found that the new primer pair produced high-quality sequences in all cases for unambiguous species identification using BOLD. Conversely, the standard barcoding primers often co-amplified the homologous Wolbachia gene and resulted in mixed chromatogram signals. These sequences showed high similarity with the bacterial endosymbiont instead of the host.

RESUMO

Hymenoptera venom anaphylaxis is the most frequent cause of anaphylaxis and responsible for about 20% of all fatal anaphylaxis cases in adults. We report two cases of fatal hymenoptera venom anaphylaxis with undiagnosed underlying mastocytosis and review the risk factors for severe or fatal hymenoptera venom anaphylaxis, as well as the specificities of its association with mastocytosis. As hymenoptera venom allergic patients with underlying clonal mast cell disorder generally lack typical skin lesions of mastocytosis, its diagnosis can easily be missed, underscoring the importance and need for diagnostic strategies in order to correctly identify these patients. Predominant cardiovascular symptoms in the absence of urticaria or angioedema following an insect sting are suggestive of underlying clonal mast cell disorder, and should be distinguished from panic attack or vasovagal syncope. Similarly, an unexplained syncope or an "idiopathic" anaphylaxis might reveal mastocytosis or hereditary alpha-tryptasemia. Acute and basal serum tryptase measurements should always be integrated in the diagnostic work-up of an insect sting reaction or unexplained syncope or shock of any origin.

RESUMO

The Oriental genus Andreimyrme Lelej, 1995 is newly reported from India. A new species A. paniya sp. nov. is described based on a female specimen from Kerala part of Western Ghats. Diagnostic features of this new species to separate it from similar species A. neaera (Mickel, 1935) and A. sarawakensis Lelej, 1996 are discussed. This new species has the mesosoma and metasoma with reddish-brown cuticle which approximates Eastern mimicry ring in North America. Andreimyrme paniya sp. nov. expresses a rare color pattern. In India such color syndromes occur in two species of the tribe Smicromyrmini and two species of the subfamily Dasylabrinae. These species inhabit the tropical moist broadleaf forest ecoregion of southern India. An updated diagnosis for males and females of Andreimyrme is given.

RESUMO

A new species of Nesolinoceras Ashmead from the Dominican Republic is described and illustrated. A key to the species and a revised and expanded distribution map is presented. This is the third species recognized for the genus, and the first one confirmed to occur in high altitude (1100 m). When compared with the previously known species, a number of unique and shared features emerged, supporting a redefinition of the genus beyond that of Santos (2016): (1) the known inter-specific variability of 48% of the examined characters increased considerably, confirming their diagnostic value at the species-level, and (2) the stability of six features support them as additionally diagnostic for the genus: 2223 flagellomeres; mesoscutum subcircular, as long as wide; scuto-scutellar carina absent, axillary trough shallow, indistinct on scutellum; subalar ridge wide, somewhat ovoid, not keeled; crossvein 1cu-a arising basad of vein 1M+Cu by about 0.3 its length; and vein 2-M only slightly longer than vein 3-M. Furthermore, two important measurements for the diagnosis of Nesolinoceras now have new, expanded ranges: areolet 1.82.6 as long as pterostigma width, and areolet 0.71.0 as long as wide. The new taxon is readily recognizable by having the body mostly brown, fully infuscated wings, and the longest ovipositor of the species, among other diagnostic features. A new geographic record and in situ photo are also provided for N. laluzbrillante Santos.

RESUMO

Aleiodes Wesmael is a large cosmopolitan genus of endoparasitoid wasps that is evidently especially speciose in the Western Hemisphere based on numbers of described species. As with most diverse insect groups, relatively little is known about Aleiodes species diversity and biology. Here I summarize what is known about Aleiodes diversity in Washington State and contiguous Inland Northwest states and province, and I report three new species recently collected by malaise trap sampling for Aleiodes in Okanogan County, WA: Aleiodes khalafi, Aleiodes okanoganensis, and Aleiodes quasiburrus. Given the number of new species (three) and first records of previously described species (two) in Washington elucidated by this study, there is evidently much work to do to reach a fair estimate of Aleiodes species diversity in the Inland Pacific Northwest.

RESUMO

The carder bee genus Pseudoanthidium Friese, 1898, is revised from China. Eight species are confirmed to occur in China, including three new species: Pseudoanthidium (Pseudoanthidium) yanruae Niu Zhu, sp. nov., P. (P.) kunesense Niu Zhu, sp. nov., P. (P.) chenggongense Niu Zhu, sp. nov. There is also one new generic assignment and synonymy: Anthidium kryzhanovskii Wu, 1962 is a junior synonym of P. (P.) orientale (Bingham, 1897). Pseudoanthidium (P.) campulodonta (Wu, 1990) is synonymized with P. (P.) tenellum (Mocsry, 1880). Here we provide descriptions for the three new species and an illustrated key to the known Chinese Pseudoanthidium.

RESUMO

The following three Japanese conifer sawflies are described or redescribed with figures of the ovipositors and male genitalia: Gilpinia hakonensis (Matsumura, 1912) from Honshu and Kyushu, Japan and Korea, G. amamiana Okutani, 1965, from Amami Oshima Island and Tokunoshima Island, Japan and G. okinawa sp. nov. from Okinawa Island, Japan. These three species are very similar and belong to the G. socia group. The lectotype for Lophyrus hakonensis Matsumura, 1912 is designated. The males of G. hakonensis and G. amamiana are described for the first time. Gilpinia fukudai (Togashi, 1964) from Honshu, Japan, is a new synonym of G. hakonensis. The host plant of G. hakonensis is Pinus densiflora Siebold et Zucc. Gilpinia amamiana is newly recorded from Tokunoshima Island. For comparison, ovipositors of five European species of the G. socia group, G. abieticola (Dalla Torre, 1894), G. frutetorum (Fabricius, 1793), G. laricis (Jurine, 1807), G. socia (Klug, 1812) and G. variegata (Hartig, 1834), are described and figured. The ovipositors of G. frutetorum, G. laricis and G. variegata are figured for the first time. Gilpinia laricis is newly recorded from Bulgaria.
