RESUMEN
BACKGROUND: Despite prison settings presenting opportunities for healthy eating and regular exercise, many incarcerated men supplement prison food with unhealthy snacks and drinks, and are less likely to achieve recommended physical activity guidelines than non-incarcerated men. This paper describes the co-development with prison staff of a healthy lifestyle intervention for delivery to incarcerated men, and feasibility testing of its delivery through prison physical education departments. METHODS: The starting point for intervention development was Football Fans in Training (FFIT), an evidence-based intervention successful in engaging men and supporting them to lose weight, make positive lifestyle changes and maintain these long term. We iteratively tested and adapted FFIT for delivery in prison gym facilities through a four Phase pilot and optimisation study. Methods used to evaluate each phase included: observations of session deliveries; semi-structured interviews with participants; and a focus group/semi-structured interviews with prison Physical Education Instructors (PEIs) who delivered the programme. Data were analysed thematically using the Framework approach. Findings from each phase informed development of the optimised programme. RESULTS: We iteratively co-developed a healthy lifestyle intervention (known as Fit for LIFE) tailored to the needs of incarcerated men and prison operational constraints. Fit for LIFE comprises elements specifically designed to address common barriers to a healthy lifestyle within prison, including: discussion of healthiest available food choices; trying out different physical activity options in the prison gym; and strategies (such as in-cell workouts) for dealing with prolonged time in cells at evenings/weekends. Weight loss was not always the most valued outcome. Instead, participants cited a wide range of behavioural, physical and mental health improvements as important to them, and were more motivated if they could focus on identifying and achieving personally relevant objectives. CONCLUSIONS: Fit for LIFE is a 10-week, group-based healthy lifestyle programme tailored for delivery to incarcerated men in prison gymnasia. Weekly 90-min sessions include informative and interactive 'classroom' activities followed by a practical physical activity training session, often with group activities. Fit for LIFE aims to help incarcerated men to: increase physical activity; reduce sedentary time; eat more healthily; and start and maintain using prison gym facilities with confidence.

Supporting ecosystem services and conserving biodiversity may be compatible goals, but there is concern that service-focused interventions mostly benefit a few common species. We use a spatially replicated, multiyear experiment in four agricultural settings to test if enhancing habitat adjacent to crops increases wild bee diversity and abundance on and off crops. We found that enhanced field edges harbored more taxonomically and functionally abundant, diverse, and compositionally different bee communities compared to control edges. Enhancements did not increase the abundance or diversity of bees visiting crops, indicating that the supply of pollination services was unchanged following enhancement. We find that actions to promote crop pollination improve multiple dimensions of biodiversity, underscoring their conservation value, but these benefits may not be spilling over to crops. More work is needed to identify the conditions that promote effective co-management of biodiversity and ecosystem services.

A series of bioassays were conducted to determine the relative toxicities and residual activities of insecticides labeled for use in blueberry (Vaccinium corymbosum L.) on natural enemies, to identify products with low toxicity or short duration effects on biological control agents. In total, 14 insecticides were evaluated using treated petri dishes and four commercially available natural enemies (Aphidius colemani Viereck, Orius insidiosus [Say], Chrysoperla rufilabris [Burmeister], and Hippodamia convergens [Guérin-Menéville]). Dishes were aged under greenhouse conditions for 0, 3, 7, or 14 d before introducing insects to test residual activity. Acute effects (combined mortality and knockdown) varied by insecticide, residue age, and natural enemy species. Broad-spectrum insecticides caused high mortality to all biocontrol agents, whereas products approved for use in organic agriculture had little effect. The reduced-risk insecticide acetamiprid consistently caused significant acute effects, even after aging for 14 d. Methoxyfenozide, novaluron, and chlorantraniliprole, which also are classified as reduced-risk insecticides, had low toxicity, and along with the organic products could be compatible with biological control. This study provides information to guide blueberry growers in their selection of insecticides. Further research will be needed to determine whether adoption of a pest management program based on the use of more selective insecticides will result in higher levels of biological control in blueberry.

A 3-yr field study was conducted at commercial juice grape (Vitis labrusca L.) vineyards to develop an economic injury level (EIL) for grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae) and to determine patterns of cluster injury. Infestation of grape clusters by P. viteana was measured biweekly from bloom until harvest, and fruit was sampled immediately before harvest to determine the yield and level of fruit injury by this pest. Comparison of fruit infestation at each sampling date to that found just before harvest revealed stronger relationships over time, and by early August at least 50% of the variation in preharvest infestation was accounted for by previous infestation. Grape yield declined with increasing infestation by P. viteana, allowing calculation of the EIL at which the value of yield lost to infestation equaled the cost of insecticide applications to prevent the infestation. Using two scenarios of pest control programs based on pyrethroid or diamide insecticides, the EILs were calculated to be 9.9 and 17.7% of clusters damaged, respectively. For use in juice grape vineyard integrated pest management programs, we propose using 5 and 10% damaged clusters at harvest as action thresholds for further testing in field trials to evaluate sampling plans and the use of thresholds to guide vineyard pest management decision-making under different insecticide scenarios.

Over two growing seasons, Isomate GBM-Plus tube-type dispensers releasing the major pheromone component of grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), were evaluated in vineyards (Vitis spp.) in Michigan, New York, and Pennsylvania. Dispensers were deployed in three different density-arrangement treatments: 124 dispensers per ha, 494 dispensers per ha, and a combined treatment with 124 dispensers per ha in the vineyard interior and 988 dispensers per ha at the vineyard border, equivalent to an overall density of 494 dispensers per ha. Moth captures and cluster infestation levels were compared at the perimeter and interior of vineyards receiving these different pheromone treatments and in vineyards receiving no pheromone. Orientation of male moths to pheromone-baited traps positioned at the perimeter and interior of vineyards was reduced as a result of mating disruption treatments compared with the nontreated control. These findings were consistent over both years of the study. Disruption of male moth captures in traps varied from 93 to 100% in treated vineyards, with the 494 dispensers per ha application rates providing significantly higher level of disruption than the 124 dispensers per ha rate, but only in 2007. Measurements of percentage of cluster infestation indicated much higher infestation at perimeters than in the interior of the vineyards in all three regions, but in both sample positions there was no significant effect of dispenser density on cluster infestation levels in either year. The contrasting results of high disruption of moth orientation to traps in vineyards that also had low levels of crop protection from this pheromone treatment are discussed in the context of strategies to improve mating disruption of this tortricid pest.

Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and inform management actions. Here, we present CropPol, a dynamic, open, and global database on crop pollination. It contains measurements recorded from 202 crop studies, covering 3,394 field observations, 2,552 yield measurements (i.e., berry mass, number of fruits, and fruit density [kg/ha], among others), and 47,752 insect records from 48 commercial crops distributed around the globe. CropPol comprises 32 of the 87 leading global crops and commodities that are pollinator dependent. Malus domestica is the most represented crop (32 studies), followed by Brassica napus (22 studies), Vaccinium corymbosum (13 studies), and Citrullus lanatus (12 studies). The most abundant pollinator guilds recorded are honey bees (34.22% counts), bumblebees (19.19%), flies other than Syrphidae and Bombyliidae (13.18%), other wild bees (13.13%), beetles (10.97%), Syrphidae (4.87%), and Bombyliidae (0.05%). Locations comprise 34 countries distributed among Europe (76 studies), North America (60), Latin America and the Caribbean (29), Asia (20), Oceania (10), and Africa (7). Sampling spans three decades and is concentrated on 2001-2005 (21 studies), 2006-2010 (40), 2011-2015 (88), and 2016-2020 (50). This is the most comprehensive open global data set on measurements of crop flower visitors, crop pollinators and pollination to date, and we encourage researchers to add more datasets to this database in the future. This data set is released for non-commercial use only. Credits should be given to this paper (i.e., proper citation), and the products generated with this database should be shared under the same license terms (CC BY-NC-SA).

Paralobesia viteana (Clemens), grape berry moth, is a major pest of grapes in Eastern North America. There is substantial regional variation in the response of male P. viteana to sex pheromone-baited monitoring traps in Michigan vineyards. Males are readily captured in traps in the southwest region, whereas in the northwest very few males are captured, despite larval infestation in grapes in both regions. Y-tube olfactometers and field experiments determined the response of male moths from northern and southern populations to the pheromone blend used in monitoring lures and to females from both regions. In Y-tube choice tests, males responded similarly to the standard pheromone blend, and males did not preferentially choose females from either region. In field trials, traps baited with unmated females were deployed to test the preference of resident males for females from the two regions and for standard pheromone lures. In southwest Michigan vineyards, significantly more males were caught in traps with a 1.0-µg standard pheromone lure than in traps with captive females collected from vineyards in both regions or in traps with a blank lure control. A similar pattern of male captures among lure treatments was observed in northwest vineyards, although many fewer males were trapped and differences among treatments were not significant. We conclude that the observed regional differences in male response to pheromone traps are not caused by variation in pheromone-mediated behavioral responses, suggesting that other biotic and/or abiotic differences determine the regional variation in captures of this species.

We monitored the phenology of oviposition by grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), in grape (Vitis spp.) vineyards, to determine the optimal timing for control of this pest. Egg deposition was monitored throughout the growing season by visually inspecting grape clusters twice weekly and counting the number of eggs. Male moths were captured on pheromone-baited traps during the same period. Two main periods of egg deposition were detected in all farms and years: the first period in June-July and the second period during August. These episodes of concentrated oviposition were separated by a brief period of low intensity but continuous oviposition. The proportion of eggs laid during the first peak ranged from 9 to 35% of all eggs laid throughout the monitoring period at each site, whereas eggs laid during the second peak ranged from 43 to 78% of all eggs laid. From 49 to 99% of male moths were captured before or during the first peak in oviposition. In field trials with varying application timing of methoxyfenozide targeting the postbloom oviposition, a single application of this selective insecticide at approximately 700 degree-days, or approximately 12% of cumulative season-long oviposition, provided significant control of grape berry moth comparable with two applications of methoxyfenozide or a three-spray program with broad-spectrum insecticides. Use of predicted oviposition phenology and selective insecticides with long residual activity can improve protection of grapes against infestation by P. viteana.

Paralobesia viteana (Clemens) (Lepidoptera:Tortricidae), the grape berry moth, is a major economic pest of cultivated grapes in eastern North America. Although pheromone lures and traps are available for monitoring this pest, male moth captures in these traps decline as the infestation risk increases through the multiple generations that occur during a season. This makes it difficult to use traps to monitor this pest's population dynamics and complicates the timing of pest management activities. To test whether seasonal changes in the plant canopy affect captures of male grape berry moth, we manipulated grapevine fruit density or canopy structure in multiple growing seasons, and measured male captures under these conditions. Removal of either 50 or 100% of the fruit clusters from vineyard plots did not consistently affect captures in pheromone traps. In 2013, significantly more males were captured in traps in plots where clusters were not removed compared to captures in traps in plots where 50 or 100% of clusters were removed, but this effect was not seen in 2014 or 2015. In the first year of a separate experiment, there were no differences in male captures between unaltered canopies and those held open artificially. In subsequent years we detected significant differences in male captures for some sample periods, and there was a prevailing trend of arithmetically more male captures in unaltered than in open canopies. We conclude that fruit presence, fruit density and canopy fullness do not reduce male P. viteana captures late in the season, and that other factors are driving this pattern.

The grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae), is a key economic pest of vineyards in eastern North America, and prevention of fruit infestation is particularly challenging along vineyard borders that are adjacent to wooded areas containing wild grape (Vitis spp.). For three years, infestation and damage in vineyards where reduced-risk insecticides were applied to borders at timings based on a degree day model (Integrated Pest Management program) were compared to that in vineyards where broad-spectrum insecticides were applied across the whole vineyard (Standard program). Infestation at vineyard borders immediately prior to harvest was consistently lower in IPM vineyards than in Standard program vineyards, and in two of the years this was also true at veraison (fruit coloring). Grape berry moth infestation was similar between treatments at vineyard interiors throughout the study, despite no insecticide applications to the interiors of the IPM program vineyards. Populations of two other key vineyard pests, the eastern grape leafhopper, Erythroneura comes (Say) (Hemiptera: Cicadellidae), and Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), were not significantly different between programs, and natural enemy captures on yellow sticky traps were also similar. The per hectare cost of insecticides applied in the IPM program was consistently lower than for the Standard program, with a significant difference in the third year of this study. We demonstrate how spatially selective applications of reduced-risk insecticides can provide improved control of grape berry moth at lower cost than standard broad-spectrum insecticide-based programs.
RESUMEN
The insect growth regulators (IGRs) tebufenozide and methoxyfenozide and the broad-spectrum insecticides azinphosmethyl, carbaryl, and fenpropathrin were compared for their activity against adult, egg, and larval stages of the grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae), under laboratory and vineyard conditions. Adult mortality was not affected by exposure to field-equivalent rates of tebufenozide or methoxyfenozide on grape clusters, whereas all the broad-spectrum compounds significantly reduced adult survival, compared with the untreated controls. Surviving adult moths laid significantly more eggs on berries treated with the IGRs than on berries treated with any of the broad-spectrum insecticides. Survival of these eggs through to late larval and pupal stages was significantly lower on methoxyfenozide-treated grapes than on untreated grapes, and no pupae were found when grapes were treated with azinphosmethyl or fenpropathrin. Neither of the growth regulator insecticides limited egg eclosion or larval development by E. viteana when insecticides were applied before egg laying, whereas broad-spectrum insecticides were effective against both eggs and neonates at this timing. When applied after egg eclosion, all insecticide treatments significantly reduced survival of grape berry moth larvae. Under vineyard conditions, berries with 1-d-old residues of tebufenozide or methoxyfenozide received more E. viteana eggs than berries treated with broad-spectrum compounds. After aging for 7 or 14 d, no significant effects on E. viteana survival were detected among treatments. Whereas broad-spectrum insecticides provide control of multiple life stages of E. viteana, integration of tebufenozide or methoxyfenozide into vineyard management programs for control of this pest will be most successful if applications are timed for egg hatch.

BACKGROUND: Immunization information systems (or registries) are increasingly being used to promote and sustain high levels of vaccination coverage. However, the perception among many providers that registry data are too incomplete to be relied on when making immunization decisions has impeded the acceptance of registries. METHODS: To evaluate registry completeness, immunization coverage levels from the San Antonio Immunization Registry System (SAIRS) were compared with coverage levels derived from immunization records from 77 (37%) of the 210 clinics participating in the Vaccines for Children (VFC) program in 1998, 44 (21%) clinics in 1999, and 10 (5%) clinics in 2000. RESULTS: Clinic data indicated an average immunization coverage level for the 4:3:1 series of 39.8%. The overall coverage level for these clinics based on registry data was 64.1%. Registry-coverage levels for these clinics were < or =65% above the coverage levels based on clinic records. CONCLUSIONS: Immunization coverage levels based on SAIRS data were the same or higher than coverage levels based on clinic records. These data suggest that San Antonio's registry data were more complete than clinic records and may assist in changing provider perceptions regarding registry data completeness.

The ultraviolet and optical telescope (UVOT) on Swift provides coverage of gamma-ray bursts and their afterglows in the 170-650 nm band, yielding multiwavelength data of considerable diagnostic power in conjunction with the Swift X-ray Telescope. The results from the first eighteen months of operation show a broad range of afterglow behaviour, with considerably more complexity in many bursts than would be expected from the simple fireball model for the explosion. We briefly illustrate the capabilities of UVOT for measuring the evolution of nearby supernovae by reference to the observations of GRB 060218, and discuss the peculiar case of GRB 060614, which apparently resides in a nearby galaxy but which did not show the expected supernova feature in its light curve due to radioactive nickel decay. We discuss how the combination of X-ray and UV/optical spectral data can be used to investigate the environment of GRB host galaxies.

Previously we demonstrated a method, Quantized Surface Complementarity Diversity (QSCD), of defining molecular diversity by measuring shape and functional complementarity of molecules to a basis set of theoretical target surfaces [Wintner E.A. and Moallemi C.C., J. Med. Chem., 43 (2000) 1993]. In this paper we demonstrate a method of mapping actual protein pockets to the same basis set of theoretical target surfaces, thereby allowing categorization of protein pockets by their properties of shape and functionality. The key step in the mapping is a 'dissection' algorithm that breaks any protein pocket into a set of potential small molecule binding volumes. It is these binding volumes that are mapped to the basis set of theoretical target surfaces, thus measuring a protein pocket not as a single surface but as a collection of molecular recognition environments.
