摘要：为明确半乳糖霉、柄篮状菌和雅致放射毛霉三种真菌对斑翅果蝇体内生理生化指标的影响，以侵染三种真菌的人工饲料饲养斑翅果蝇幼虫，并测定其体内部分物质含量和酶的活性。结果表明，取食接种雅致放射毛霉和柄篮状菌的人工饲料后，斑翅果蝇体内蛋白含量显著低于对照（取食不接菌人工饲料）；取食接种雅致放射毛霉的人工饲料后，斑翅果蝇体内山梨醇含量显著低于对照；取食接种三种真菌的人工饲料后，斑翅果蝇体内纤维素酶和碱性磷酸酶活性均无显著变化，脂肪酶活性均显著低于对照。本研究可为探索真菌与果蝇间的协同进化关系提供重要的理论基础。

AbstractTo define the effects of three kinds of fungi on physiological and biochemical indexes of Drosophila suzukii. The larvae of Drosophila suzukii were reared with artificial diets infected by three kinds of fungi respectively， and then some enzymes and material contents in larvae were determined. The results showed that the protein content in Drosophila suzukii larvae reared with diets infected by Actinomucor elegans and Talaromyces stipitatus were significantly lower than that of control （larvae reared with diet not infected by fungus）. The content of sorbitol in insects reared with Actinomucor elegans were significantly inferior to that of control.The lipase activity of three fungi treatments were all lower than that of control. But there was no significant difference between cellulose and alkaline phosphatase activity in Drosophila suzukii feeding with different artificial diets. This study provided theoretical bases for co-evolutionary interactions between fungus and Drosophila suzukii.

斑翅果蠅Drosophila suzukii Matsumura，又称铃木氏果蝇，属于双翅目（Diptera）果蝇科（Drosophilidae），是一种重要的水果害虫。斑翅果蝇雌虫能用其发达的产卵器划破果皮，将卵产在即将成熟的果实中，其后代孵化后在果实中蛀食，严重损害水果质量，其产卵孔也会招致其它果蝇和一些细菌及真菌进一步侵染，使水果失去经济价值。斑翅果蝇寄主广泛，可为害如蓝莓、黑莓、红树莓、樱桃、草莓、李子、桃子、葡萄、无花果、猕猴桃、梨等[1]软皮水果。在日本、北美、欧洲都造成过严重的经济损失[2-4]，目前仍无有效的防治措施。

目前，斑翅果蝇的研究主要集中在种类的组成与分布[5]、形态鉴定、分类检索、寄主与危害、生物生态学特性以及防治措施[6-8]等方面。……
