Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an invasive, polyphagous fruit fly that attacks soft-skinned fruits. Originally from Asia, D. has successfully invaded the United States and European South American countries. At present, calendar-based insecticide applications are used to combat suzukii. Here, we evaluate a behaviorally based attract-and-kill management technique using attracticidal spheres reduce infestations in raspberries. In laboratory bioassays aimed at identifying effective toxicants, containing dinotefuran 1.0% a.i. killed 100% of within 5 min.

Attracticidal effectively attract kill under conditions, indicating this behavioral strategy holds promise management.

Identifying candidate host plants for trap cropping against Drosophila suzukii in vineyards

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.

Olfactory Preference of Drosophila suzukii Shifts between Fruit and Fermentation Cues over the Season: Effects of Physiological Status

Published: July 6, 2019

Worldwide monitoring programs of the invasive fruit pest Drosophila suzukii Matsumura (Diptera: Drosophilidae), using fermentation baits like apple cider vinegar (ACV), revealed a counterintuitive period low trap catches during summer, followed by an autumn peak. In this study, we demonstrate that ACV baited traps indeed provide distorted image D. population dynamics as it is possible to capture higher numbers "low period" with synthetic lures. It was hypothesised preference populations for cues most pronounced autumn, winter and spring, while flies prefer fresh summer seasonal related changing physiology over season. To test hypothesis, between (ACV) host fruits (strawberries) effect (sex, morphology feeding, mating reproductive status) investigated both in olfactometer laboratory experiments year-round field experiment. demonstrated protein deprived females, virgin females full complement unfertilised eggs males show strong fully fed morph generally cues.

Insects rely on their sense of smell to locate food and hosts, find mates select sites for laying eggs. Use volatile compounds, such as essential oils (EOs), repel insect pests disrupt olfaction-driven behaviors has great practical significance in integrated pest management. However, our knowledge the olfaction-based mechanisms EO repellency is quite limited.We evaluated peppermint oil nine plant components Drosophila melanogaster, a model olfaction study, D. suzukii, major fruit crop pest. All volatiles, menthone, (-)-menthol, menthyl acetate, (R)-(+)-limonene, nerol, (+)-fenchone, (-)-α-thujone, camphor, norcamphor oil, elicited melanogaster dose-dependent manner.

Insect pest invasions cause significant damage to crop yields, and the resultant economic losses are truly alarming. Climate change trade liberalization have opened new ways of invasions. Given consumer preference towards organic agricultural products environment-friendly nature natural control strategies, biological is considered be one potential options for managing invasive insect pests. Drosophila suzukii (Drosophilidae) an extremely damaging fruit pest, demanding development effective sustainable strategies. In this study, we assessed parasitoid Leptopilina japonica (Figitidae) as a biocontrol agent D. using ecological niche modeling approaches. We developed global-scale models both identify four components necessary derive based, target oriented prioritization approach plan programs : (i) distribution , (ii) L.

Factors influencing oviposition behaviour of the invasive pest, Drosophila suzukii, derived from interactions with other Drosophila species: potential applications for control

Pest Management Science, Journal Year: 2023, Volume and Issue: 79(11), P. 4132 - 4139

Published: July 30, 2023

Drosophila suzukii (Matsumura) or spotted wing is a worldwide invasive pest of soft- and stone-fruit production. Female D. lay their eggs in ripening fruit the hatched larvae damage from inside, rendering it unmarketable causing significant economic loss. Current methods to reduce population field primarily rely on chemical insecticides which are not sustainable long-term solution increase risk resistance developing. Several studies demonstrate that when encounter coexist with other food source, this usually disadvantage suzukii, leading reduced oviposition increased larval mortality. These effects have potential be exploited management perspective. In review we summarise recent research articles focusing interspecific interactions between species aimed at understanding how drives behaviour.

Abstract Chemical control of Drosophila suzukii (Diptera: Drosophilidae) based on the use insecticides is particularly challenging as insect attacks ripening fruits shortly before harvest. An alternative strategy may rely yeasts phagostimulants and baits, applied canopy attract-and-kill formulations. The aim this research was to identify most attractive among six yeast species for D. : Saccharomyces cerevisiae , Hanseniaspora uvarum Clavispora santaluciae Saccharomycopsis vini Issatchenkia terricola Metschnikowia pulcherrima . volatile profile C described first time. Behavioural experiments identified H. S. yeasts. characterization headspace volatiles using direct (DHS) solid-phase microextraction (SPME) revealed several strain-specific compounds. With DHS injection, 19 were characterised, while SPME 71 compounds constituting headspace. Both analyses terpenoids including β-ocimene, citronellol, ( Z )-geraniol (nerol), geranial distinct constituents further investigated closed-loop stripping analysis (CSLA) electroantennography. Out 14 quantified by CSLA, ethyl acetate, isoamyl β-myrcene, benzaldehyde linalool detected antennae might generate strong attractiveness uvarum. Our results highlight a attraction various associated with both flies their habitat demonstrate how different sampling methods can impact compound characterization. It remains be demonstrated whether special adaptations certain what extent metabolites causing are interchangeable.
