Yeasts play an important role in the life cycle and biology of the insect pest Drosophila suzukii (Matsumura), commonly known as the spotted wing drosophila (SWD). Adult and larvae of this species are known to feed and benefit from yeast in their diet. In addition, yeasts were found to be attractive to SWD and were repeatedly found to be associated with SWD. Among those, Hanseniaspora uvarum is the most commonly mentioned. The present study explores the chemical composition and the effects of three H. uvarum strains and five yeast species (Saccharomyces cerevisiae, Candida sp., Issatchenkia terricola, Metschnikowia pulcherrima and Saccharomycopsis vini) in the diet of SWD adults. The different yeast species used in this study influenced mortality, fecundity and ingestion by SWD females. Hanseniaspora uvarum and S. vini were preferably ingested and increased fecundity of SWD females. The intra- and extracellular concentrations of compounds, such as amino acids, carbohydrates, sugar alcohols and organic acids, produced or consumed by yeasts differed among the species. Knowledge of the interaction of different yeast species with SWD and specific differences in the profile of compounds of yeast can help to improve the development of control strategies against the insect pest by promoting the ingestion of attract-and-kill formulations based on the combinations of yeasts and an appropriate insecticide.

酵母物种影响铃木果蝇成虫的摄食和适应能力

酵母菌在铃木果蝇（Datsuophila suzukii）（Matsumura）（通常称为斑翅果蝇（SWD））的生命周期和生物学中起着重要作用。已知该物种的成年和幼虫在饮食中以酵母为食并从中受益。另外，发现酵母对SWD具有吸引力，并反复发现与SWD相关。其中，最常提及的是Hanseniaspora uvarum。本研究探讨了三种H.uvarum菌株和5种酵母菌（酿酒酵母，假丝酵母​​（Candida sp。），Issatchenkia terricola，Metschnikowia pulcherrima和Saccharomycopsis vini）的化学成分及其影响）的饮食。这项研究中使用的不同酵母菌种影响了社署女性的死亡率，繁殖力和摄入。最好摄入Hanseniaspora uvarum和S. vini，增加SWD雌性的繁殖力。酵母产生或消耗的化合物（例如氨基酸，碳水化合物，糖醇和有机酸）的细胞内和细胞外浓度在不同物种之间有所不同。了解不同酵母物种与SWD的相互作用以及酵母化合物的特征方面的特定差异，可通过促进基于酵母组合的消化吸收和杀灭制剂的摄入来帮助改进针对害虫的防治策略。和适当的杀虫剂。
