在实验室条件下，研究了昆虫病原真菌球孢白僵菌（Beauveria bassiana（Balsamo-Crivelli）Vuillemin，子囊菌门：肉座菌目）与蚜虫寄生性天敌疏顶格孢（Diaeretiella raismMcIntoch，膜翅目：茧蜂科）之间的相互作用。用B溶液对桃蚜（Myzus persicae Sulzer）若虫进行24 h暴露，然后分别在0、24和48 h进行喷雾处理。巴西纳。同样，蚜虫也用B喷雾。然后在0、24和48 h暴露于拟寄生蜂。寄生率为13 ~ 66.5%，与对照组（不加B）相比，两种药剂在0-24 h内接触的处理组寄生率显著降低。bassiana）。寄生蜂出现与B的处理产生负面影响。白僵菌喷洒和随后暴露于D.很不好。雌成虫寿命缩短。B处理的F1代出现了明显的早熟现象。白僵菌喷雾这两种生防药剂可联合应用于防治稻曲病。桃，其中该用途需要有效的时间管理以避免拮抗相互作用。
The interactions between the entomopathogenic fungus Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Ascomycota: Hypocreales) and the aphid parasitoid Diaeretiella rapae McIntoch (Hymenoptera: Braconidae) were evaluated under laboratory conditions. Nymphs of Myzus persicae Sulzer (Hemiptera: Aphididae) were first exposed to parasitoid females for 24 h and then 0, 24, and 48 h afterwards sprayed with a solution of B. bassiana. Likewise, aphids were also sprayed with B. bassiana and then exposed to parasitoids at 0, 24, and 48 h afterwards. Parasitism rate varied from 13 to 66.5%, and were signi_cantly lower in treatments where the two agents were exposed within a 0-24 h time interval compared with the control (without B. bassiana). Parasitoid emergence was negatively affected in treatments with B. bassiana spraying and subsequent exposure to D. rapae. Decreases in longevity of adult females of the D. rapae F1 generation were observed in treatments with B. bassiana spraying. The application of these two biological control agents can be used in combination on the control of M. persicae, wherein this use requires effective time management to avoid antagonistic interactions.
