Abstract BACKGROUND Drosophila suzukii has dispersed widely from its native Asian range since 2008. Its arrival in the UK is resulting economic losses soft‐ and stone‐fruit crops caused by larvae feeding on flesh of ripening fruit. Although a large amount research been directed at controlling this pest, it presently unknown how invasive species interacts with species. RESULTS In work reported here, D. or melanogaster adults were introduced to substrates pre‐inoculated eggs same other...

Drosophila suzukii Matsumura is a damaging invasive pest of sweet cherry. Using series laboratory leaf contact assays, semi-field, and orchard spray programs we aimed to determine the impact insecticide on D. adult mortality oviposition in cladding-protected cherry crops. Tests included assessing after with leaves sprayed either one or two weeks previously emergence adults from fruits. Spinosad, lambda-cyhalothrin, acetamiprid, lime, pyrethrin, deltamethrin, cyantraniliprole all reduced...

ABSTRACT Current control of the invasive pest Drosophila suzukii relies primarily on insecticides, including incorporation phagostimulant baits. The impact insecticidal bait sprays beneficial insects in crops is largely unknown. In a laboratory and field trial, we exposed non‐target to insecticides with or without compared these non‐insecticide controls. arena tests, assessed mortality. subsequent commercial raspberry 1 m width spray bands were applied weekly, using alternating 25% 50% rates...

Abstract BACKGROUND European tarnished plant bug, Lygus rugulipennis (Heteroptera: Miridae), is a polyphagous pest damaging range of arable and horticultural crops. Management reliant upon chemical insecticides for control. These studies developed synthetic semiochemical push–pull control strategy to reduce numbers L. subsequent fruit damage in UK strawberry Using series small field experiments testing commercial crops we explored the efficacy hexyl butyrate (HB) as push element female sex...

Abstract Behavior and fitness are important ecological traits frequently measured in insect bioassays. A common method to measure them soft‐bodied herbivorous insects involves confining individuals plant leaves using clip cages. Although studies have previously highlighted the negative effects of cages on leaf physiology, little is known about impact that this confinement has fitness. The responses different aphid genotypes/clones containment methods not been investigated. Here we key...

Drosophila suzukii is a horticultural pest on global scale which causes both yield and economic losses range of soft- stone-fruit. Tackling this problematic but exploiting behavioral rhythms could increase the impact control. To do this, better understanding patterns needed. Within study we aimed to investigate in reproductive behavior wild D. under natural conditions field. Environmental parameters were also recorded decipher how they influence these rhythms. Assays then performed...

Understanding behavioral rhythms in a pest species can contribute to improving the efficacy of control methods targeting that pest. However, some species, patterns recorded artificial conditions contrast greatly with observed wild-type rhythms. In this study, we identify determinants daily activity soft and stone fruit Drosophila suzukii. The impact gender, space, social housing, temperature, light, fly morph, circadian clock on D. suzukii locomotor was investigated. Assays were performed...

The pear (Pyrus communis L.) cultivar, Conference, is parthenocarpic but misshapes and marketable fruit losses of 6% at harvest are common. In other studies, insect flower visitors identified as important for apple quality, far fewer studies have examined the effects insects cross-pollination on quality. Using a range replicated field experiments, this project aimed to determine the; 1) biodiversity blossom visitors, 2) pollen limitation quality function distance from orchard edge number 3)...

The unintentional introduction of Drosophila suzukii (Matsumura) from Asia has caused global economic losses in the soft and stone fruit industries. Pesticide use can have unintended negative impacts on natural enemies, disrupting attempts to incorporate integrated pest management programmes. Generalist predators could potentially act as biocontrol agents D. suzukii. In this context, predatory capabilities European earwig (Forficula auricularia) were investigated.In semi-field conditions, F....

The worldwide invasive insect pest, Drosophila suzukii Matsumura (spotted-wing Drosophila), lays eggs in soft and stone fruit before harvest. Hatched larvae cause collapse significant economic losses. Current control methods rely primarily on foliar insecticide applications, which are not sustainable long-term solutions due to regulatory restrictions the risk of resistance developing. We showed that D. were deterred from laying artificial media previously visited by its sister...

Economic losses in a range of fruit crops due to the Drosophila suzukii (Matsumura) have become severe. Removal and treatment waste, which may harbor D. suzukii, is key step preventing reinfestation production. Natural fermentation for disinfesting wastes from was examined at ambient air temperatures 12-20 °C. Soft stone infested with eggs, larvae, pupae melanogaster (Meigen) or were placed sealed vessels containing wastes, samples retrieved intervals tested emergence adults. Mean waste...

Abstract Spotted wing drosophila ( Drosophila suzukii Matsumura) is a major pest of fruit crops with global significance. Effective control reliant on uniformly spraying insecticides all crop foliage. To encourage attraction and ingestion insecticides, phagostimulant baits can be employed in ‘attract kill’ strategies. In semi-field trials we compared (1) full field foliar sprays two spinosad cyantraniliprole, (2) reduced [40%] (3) low [4%] rates the to D. reduce insecticide residues sweet...
