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

Our review draws attention to a suite of tactics that form the integrated pest management (IPM) approach being developed for use in apple, pear, and cherry solve new continuing problems. Tactics include development cultural practices, behavioral tools, spray programs, biocontrol. All these have be embedded seasonal programs heavily dependent on insecticide sprays. Some approaches are conflict with sprays, adjustments made. Many actions support current hopefully will make more less reliance pesticides. Others tools can adopted gain knowledge guide rational decision-making. The twenty-first century is nearly quarter done, our suggests we made good progress there remains much do.
