Spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a vinegar fly of Asian origin, has emerged as devastating pest small and stone fruits throughout the United States. Tolerance for larvae is extremely low in fresh market fruit, management primarily achieved through repeated applications broad-spectrum insecticides. These are neither economically nor environmentally sustainable, can limit markets due to insecticide residue restrictions, cause outbreaks secondary pests, select resistance. Sustainable integrated programs include cultural control tactics various nonchemical approaches reducing populations that may be useful managing D. suzukii. This review describes current state knowledge implementation different controls including preventative such crop selection exclusion well strategies reduce habitat favorability (pruning; mulching; irrigation), alter resource availability (harvest frequency; sanitation), lower suitability fruit postharvest (cooling; irradiation). Because climate, horticultural practices, crop, underlie efficacy, feasibility, affordability tactics, potential these discussed across production systems.

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.

Reproductive Site Selection: Evidence of an Oviposition Cue in a Highly Adaptive Dipteran, Drosophila suzukii (Diptera: Drosophilidae)

Environmental Entomology, Год журнала: 2020, Номер 49(2), С. 355 - 363

Опубликована: Янв. 7, 2020

Drosophila suzukii (Matsumura) is a vinegar fly species that originates from Eastern Asia and has spread throughout Europe the Americas since its initial detection in United States 2008. Its relatively large, sclerotized, serrated ovipositor enables ability to penetrate ripening fruits, providing protected environment for egg larval stages. Because mechanism of oviposition site selection D. matter hypothesis, aim present study was elucidate behavioral chemical aspects short-range ovipositional within context reproductive biology. The preference lay eggs on artificially pierced, previously infested, or intact fruits tested. Video recordings photographic evidence documented release an anal secretion over fruit surface near sites. Gas chromatographic analysis revealed presence 11 compounds detected only skin egg-infested berries. Electroantennographic experiments with both sexes highlighted importance six volatile compounds: methyl myristate, palmitate, myristic acid, lauric palmitic palmitoleic acid. Finally, synthetic blend composed ratio similar found berries increased rate conspecific females. Data our work suggest identified volatiles are cues selection. We discuss how these may affect fitness suzukii. knowledge gained this accelerate establishment control strategies based interference disruption communication during processes.

Social signals mediate oviposition site selection in Drosophila suzukii

Scientific Reports, Год журнала: 2021, Номер 11(1)

Опубликована: Фев. 15, 2021

The information that female insects perceive and use during oviposition site selection is complex varies by species ecological niche. Even in relatively unexploited niches, females interact directly indirectly with conspecifics at sites. These interactions can take the form of host marking re-assessment prior sites decision-making process. Considerable research has focused on niche breadth preference polyphagous invasive pest Drosophila suzukii Matsumura (Diptera: Drosophilidae), but little exists how conspecific signals modulate behavior. We investigated three layers social D. may selection-(1) pre-existing egg density, (2) larval occupation, (3) adults. found presence larvae marking, not influenced behavior two factors interacted over time. Adult appeared to deter only an unmarked substrate. results are first behavioral evidence for a pheromone Drosophila. findings also help elucidate infestation patterns within crop fields natural areas.

Sugar sensation and mechanosensation in the egg-laying preference shift of Drosophila suzukii

eLife, Год журнала: 2022, Номер 11

Опубликована: Ноя. 18, 2022

The agricultural pest Drosophila suzukii differs from most other species in that it lays eggs ripe, rather than overripe, fruit. Previously, we showed changes bitter taste sensation accompanied this adaptation (Dweck et al., 2021). Here, show D. has also undergone a variety of sweet sensation. weaker preference melanogaster for laying on substrates containing all three primary fruit sugars: sucrose, fructose, and glucose. Major subsets sensilla have lost electrophysiological responses to sugars. Expression several key sugar receptor genes is reduced the organs suzukii. By contrast, certain mechanosensory channel genes, including no mechanoreceptor potential C, are expressed at higher levels suzukii, which stiff substrates. Finally, find responds differently combinations cues. Thus, two differ sensation, mechanosensation, their integration, likely contribute differences egg-laying preferences nature.

Winter Is (Not) Coming: Is Climate Change Helping Drosophila suzukii Overwintering?

Biology, Год журнала: 2023, Номер 12(7), С. 907 - 907

Опубликована: Июнь 25, 2023

Anthropogenic challenges, particularly climate change-associated factors, are strongly impacting the behavior, distribution, and survival of insects. Yet how these changes affect pests such as Drosophila suzukii, a cosmopolitan pest soft-skinned small fruits, remains poorly understood. This polyphagous is chill-susceptible, with cold temperatures causing multiple stresses, including desiccation starvation, also challenging immune system. Since invasion Europe United States America in 2009, it has been rapidly spreading to several European American countries (both North South American) African Asian countries. However, globalization global warming allowing an altitudinal latitudinal expansion species, thus colonization colder regions. review explores D. suzukii adapts survive during seasons. We focus on overwintering strategies behavioral adaptations migration or sheltering, seasonal polyphenism, reproductive adaptations, well metabolic transcriptomic response cold. Finally, we discuss continuation change may promote ability this species spread, what mitigation measures could be employed overcome cold-adapted suzukii.

Winter fruit contribution to the performance of the invasive fruit fly Drosophila suzukii under different thermal regimes

Insect Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

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.
