Published: July 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.

This study explored the thermal response of Drosophila suzukii, an injurious insect pest present in many countries worldwide, at different controlled conditions. species is responsible for several economic losses soft fruit cultivations, develops on ripening fruits, and has capability to quickly adapt new territories climates, closing multiple generations per year. Given its high invasive potential increasing need low-impact control strategies, in-depth exploration biology this stage fundamental. Specimens Italian strain from Apulia were reared growth chambers constant temperatures (6, 9, 13, 18, 20, 24, 25, 26, 27, 28, 29, 31, 32 33 °C). The life cycle each specimen was individually tracked egg death adults, considering larval stages distinction as well.

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.

In insects, antennal ionotropic receptors (IRs) and odorant (ORs) are among the main sensors of olfactory cues. To functionally characterize subunits from these receptors, use ab3A neurons transgenic Drosophila melanogaster represented one most powerful tools, allowing identification ligands (deorphanization) decrypting their pharmacological properties. However, further investigation is needed to shed light on possible metabotropic functionalities behind insect test potentials up-to-now-used empty neuronal systems express belonging variegate receptor classes. this project, we adopted updated system various ranging human ORs working as G-protein coupled IRs ORs. Testing expressing into by single sensillum recording did not result in an OR response ligands, but it rather re-established spiking neurons. When D. expressed ORs, both heterologous cis-expressed were non-functional, suzukii OR19A1 subunit responded a wide asset distinguishing phasic or tonic compound-dependent effects. Despite activation some resulted study deorphanized key demonstrating its binding alcohols, ketones, terpenes, esters.

Abstract BACKGROUND The global pest spotted winged drosophila ( Drosophila suzukii ) continues to have a significant economic impact on fruit production in areas where it is established, addition newly invaded ranges. Management activities spanning national biosecurity responses farm‐scale control are limited by the inability predict timing and severity of seasonal outbreaks D. its climatic drivers. RESULTS Here, we compiled analysed data international abundances for under different climates, crop types management contexts improve predictability population dynamics. In relating environmental predictors, specifically temperature, found strong negative effects exposure high low temperatures during preceding month. Unlike most regional studies phenology that focus temperature physiological development range, show thermal extremes better explain fluctuations. CONCLUSION Although trap catches remain an indirect measure infestations must be interpreted carefully terms risk, our results should support monitoring programmes through enhanced knowledge factors affecting activity. suggests late‐season strategies focusing manipulating microclimates above 25 °C can reduce abundance. We early season abundance modulated climate, particularly depth cold experienced time interval.
