(Matsumura), is a globally invasive pest of soft and stone fruit. To survive winter in temperate zones it enters a reproductive diapause in a morphologically distinct phenotype. Phagostimulant baits can be combined with insecticides in attract-and-kill strategies for control. We investigated the effectiveness of single yeast species and combinations of co-fermented yeast phagostimulant baits when combined with insecticides in laboratory assays against both summer- and winter-morph . or + combined with lambda-cyhalothrin or cyantraniliprole, and combined with cyantraniliprole caused significantly higher mortality in winter- compared to summer-morph . Additionally, lambda-cyhalothrin combined with + resulted in greater mortality compared to single yeasts, for both summer- and winter-morphs and for summer-morphs. + with spinosad significantly reduced the time-to-kill (50%) of summer-morphs compared to insecticide alone. Most yeast-based baits were comparable in terms of attract-and-kill efficacy to Combi-protec, a commercially available bait, although or + in with cyantraniliprole were less effective. Our study suggests that yeast phagostimulants in attract-and-kill strategies should be adjusted for summer- and winter-morph for more effective control.
（松村果蝇）是一种全球范围内对软果和核果具有侵袭性的害虫。为了在温带地区越冬，它会进入一种形态上独特的表型的生殖滞育状态。在诱捕杀灭策略中，取食刺激诱饵可与杀虫剂结合用于防治。我们在实验室试验中研究了单一酵母菌种以及共同发酵的酵母取食刺激诱饵组合与杀虫剂结合时，对夏季形态和冬季形态果蝇的有效性。……或……与高效氯氟氰菊酯或氰虫酰胺结合，以及……与氰虫酰胺结合，与夏季形态果蝇相比，在冬季形态果蝇中导致的死亡率显著更高。此外，对于夏季形态和冬季形态果蝇，高效氯氟氰菊酯与…… + ……结合导致的死亡率高于单一酵母，对于夏季形态果蝇也是如此。与单独使用杀虫剂相比，…… + ……与多杀菌素结合显著缩短了夏季形态果蝇的半数致死时间。大多数基于酵母的诱饵在诱捕杀灭效果方面与市售诱饵Combi - protec相当，尽管……或…… + ……与氰虫酰胺结合效果较差。我们的研究表明，在诱捕杀灭策略中，应针对夏季形态和冬季形态果蝇调整酵母取食刺激物，以实现更有效的防治。
