Опубликована: Июль 26, 2021

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as spotted-wing drosophila (SWD), is a pest native to Southeast Asia. In the last few decades, has expanded its range affect all major European and American fruit production regions. SWD highly adaptive insect that able disperse, survive, flourish under of environmental conditions. Infestation by generates both direct indirect economic impacts through yield losses, shorter shelf life infested fruit, increased costs. Fresh markets, frozen berries, export programs have been impacted due zero tolerance for infestation. As control rely heavily on insecticides, exceedance maximum residue levels (MRLs) resulted in crop rejections. The impact particularly severe organic operations, mainly limited availability effective insecticides. Integrated management (IPM) could significantly reduce chemical inputs but would require substantial changes horticultural practices. This review evaluates most promising methods studied part an IPM strategy against across world. For each considered techniques, effectiveness, impact, sustainability, stage development are discussed.

Abstract The spotted wing drosophila (SWD), Drosophila suzukii Matsumura (Diptera: Drosophilidae), is a serious pest in vineyards where it difficult to control. Trap cropping, which involves manipulating the host plant composition crop vicinity lure away from grapes and towards more attractive fruits, might be an interesting but so far neglected control approach limit SWD egg-laying grapes. An ideal trap should than actual ideally restrict development. We determined attractiveness of fruits 60 species for their suitability larval development laboratory assays. Compared grapes, 16 were strongly preferred by females additionally inhibited larvae into adults. Host preference was influenced hardness fruit skin, marginally affected acidity fruits. However, none measured traits had significant effect on emergence success SWD. All candidate plants further tested potential reduce infestation provide practical advice next steps taken implementing successful cropping strategy against commercial vineyards.

Опубликована: Янв. 3, 2025

Invasive floral species can affect the native plant-pollinator interactions. While impact of such invasives within plant communities is extensively documented, understanding their 'proximity' effects – where invasive spatially influence pollinators biodiversity remains comparatively obscure and requires further investigation. We quantified pollination dynamics associated with Erigeron karvinskianus, an invasive, on flora in Nainital, western Himalaya. During 162 surveys, we explored foraging 33 insects E. karvinskianus across plots from six sites, subjected to two groups, Begonia crenata proximity B. distant karvinskianus. Apis cerana, mellifera Colias fieldii performed major was correlated temperature reward. designed a mixed linear model (MELM) found that had more flower visitor density when close landscapes invaded Our findings highlight 'proximity effect' positively affects pollinator visitation by enhancing activity landscapes.

Polyphagous insect species develop using multiple host plants. Often considered beneficial, polyphagy can also be costly as nutritional quality may vary. Drosophila suzukii (Matsumura) is an invasive that on numerous fruit over the annual cycle. Here, we assessed contribution of winter-available to development seasonal populations D. suzukii, under fluctuating late winter/early spring temperature regimes. We infested artificial diet and three suitable available in (Aucuba japonica, Elaeagnus ×submacrophylla, Viscum album) with larvae regimes: constant 20 °C, controlled regime 8-15 °C (12 h light at 8 12 dark 15 °C), uncontrolled outdoor during spring. As expected, fly performance was impaired by early spring-like environmental conditions, whatever diet, winter were suboptimal diets compared thermal regime. However, cold regimes, ranking supporting best changed, highlighting occurrence physiological trade-offs. Winter-acclimated females preferentially oviposited A. japonica and/or E. regime, which does not support preference-performance hypothesis. This finding discussed context management strategies.

Abstract BACKGROUND Drosophila suzukii is an invasive pest causing high losses of agricultural crops. Conventional treatment strategies are considered problematic for their risk inducing resistance and environmental harm. Photodynamic Inactivation (PDI) based on the photosensitizer‐mediated light‐dependent generation reactive oxygen species. Natural food‐grade photosensitizers, such as food additive sodium magnesium chlorophyllin (Chl, E140), have been proven effective against microbial pathogens several pests. The aim this study to assess whether principle Chl‐based PDI D. could be transferred from laboratory towards practical conditions. RESULTS We prove that photokilled after feeding 5 mM Chl with 3% sucrose (98.4% median moribundity, 9 h drug light interval, 78.9 J/cm 2 radiant exposure). Therefore, aspects safety feasibility were assessed, using streamlined variations same assay: required photosensitizer concentration reduced 0.5 (90.1% moribundity 6 days 315.6 illumination LEDs). was photoactivable sunlight (92.5% 294.5 1 Chl). Offering alternative lures did not impair effect. Photobleaching rendered non‐toxic (2.5% bleaching subsequent 157.8 ). Furthermore, fluorescence microscopy Chl‐fed flies confirmed accumulation in flies' intestines. CONCLUSION Our findings demonstrate harnessed a safe management © 2025 Author(s).

Abstract Diptera is one of the biggest insect orders and displays a large diversity visual adaptations. Similarly to other animals, dipteran process mediated by opsin genes. Although function these genes are well studied in key model species, comprehensive comparative genomic study across phylogeny missing. Here we mined genomes 61 reconstructed evolutionary affinities 528 genes, determined selective pressure acting different species. We found that opsins underwent several lineage-specific events, including an independent expansion Long Wave Sensitive flies mosquitoes, numerous family-specific duplications losses. Both Drosophila Anopheles complement derived comparison with ancestral state. Molecular studies suggest gene turnover rate, overall mutation site-specific higher than Drosophila. Overall, our findings indicate extremely variable pattern evolution dipterans, showcasing how two similarly aged radiations, Drosophila, characterized contrasting dynamics this family. These results provide foundation for future on system.
