Abstract Drosophila suzukii is a pest of soft and stone fruits that attracted to yeast volatile metabolites. has distinct summer winter morphs which are found in different habitats. Complex communities yeasts likely differ between habitats thus we hypothesized their attraction volatiles from species combinations species. We presented D. with isolation combinations, as either post-culture mixes or co-cultured, measured activity the flies laboratory choice tests Locomotor Activity Monitor proxy for attraction. Candida zemplinina was more attractive than when cultured both sterile strawberry juice (SSJ) artificial culture media (YPD). No significant correlations were principle component scores derived single profiles fly activity. There also differential certain mixes, most notably post SSJ Hanseniaspora uvarum C. consistently morphs. Mixtures Metschnikowia pulcherrima + Pichia pijperi H. M. P. YPD preferred by morphs, whilst co-cultures . However, co-culturing did not enhance compared constituent morph. Differential suggests options new bait formulations integrated management strategies may be tailored better target

Drosophila suzukii, a significant sweet cherry pest, has traditionally been controlled using broad-spectrum insecticides. Various yeasts are known to attract and stimulate flies feed on yeast-covered surfaces. We investigated an attract-and-kill formulation based the yeast Hanseniaspora uvarum insecticide spinosad, applied 80–100 cm wide canopy strip at 1-m height in six field trials across Italy Germany manage D. suzukii infestation cherry. The formulation, dose ranging from 21.6 34.9 g per hectare of according training system, decreased percentage infested cherries by 41.74–84.26% average number deposited eggs 79.51–95.56%. efficacy was comparable conventional application spinosad alone, which 84 216 hectare. 53.00–92.00% reduced 77.10–92.96%. technique led reduction up 90% use targeting limited section tree. targeted approach not only minimized quantities hectare, but also resulted lower residue levels treated fruits.
