苹果蠹蛾是苹果和梨的重要害虫之一。本研究评价了颗粒体病毒、苏云金芽孢杆菌（Bt）菌株及其组合对黄瓜炭疽病的防治效果。中国的苹果蠹。从苹果蠹蛾（Cydia pomonella）体内分离到一株苹果蠹蛾颗粒体病毒（CpGV）。在中国甘肃的一个果园里发现了苹果蠹蛾的尸体。滴食法测定了CpGV分离株（CpGV-C1）对三龄幼虫的半数致死浓度（LC_（50））。苹果蠹蛾幼虫为770 OBs µl−1。Bt C-33和kurstaki HD-1对三龄幼虫的LC 50值分别为26.3 µg ml−1和15.7 µg ml−1。田间药效试验表明，CpGV-C1及其与Bt复配对黄瓜霜霉病具有较好的防治效果。苹果园内苹果蠹蛾幼虫与高效氯氰菊酯相似。说明CpGV与Bt联合应用可有效地保护苹果果实免受苹果炭疽病的危害。因此，有潜力开发一种低成本、高效的杀虫剂。
Abstract Codling moth, Cydia pomonella, is one of the most serious pests of apple and pear worldwide. This study evaluates the efficacies of a granulovirus, a Bacillus thuringiensis (Bt) strain and their combination in the control of C. pomonella in China. A Cydia pomonella granulovirus (CpGV) was isolated from C. pomonella cadavers in an orchard in Gansu, China. Droplet-feeding bioassays showed the median lethal concentration (LC50) of this CpGV isolate (CpGV-C1) against the third instar C. pomonella larvae was 770 OBs µl−1. The LC50 values of Bt C-33 and kurstaki HD-1 against the third instar larvae were 26.3 µg ml−1 and 15.7 µg ml−1, respectively. Field tests indicated the control efficacies of CpGV-C1 and the combination of CpGV-C1 and Bt against C. pomonella larvae in apple orchards were similar to that of beta-cypermethrin. Our data demonstrated that the combination of CpGV and Bt might effectively protect apple fruits from the damage of C. pomonella larvae and had the potential to be developed as a low-cost, highly effective insecticide.
