摘要
报道了利用卵孢白僵菌 (Beauveriabrongniatii)防治苗圃地下害虫蛴螬的应用技术。防治东北大黑鳃金龟子 (Holotrichiadiomphalia)幼虫 ,每公顷施菌量 6 0～ 90kg ,防治效果为 6 8.8%～ 86 .0 %。白僵菌和化学农药混用有一定的增效作用 ,防治效果最高可达 91%。同时结合苗圃不同的耕作方式 ,提出了床基施菌、苗木沟施菌、垄式床基施菌、垄式中耕施菌、苗木生长期施菌 5种施菌方法 ,除垅式床基施菌外 ,其它 4种施菌方法的防治效果达 76 .1%～ 83 .1% ,虫量和苗木被害率都较对照有明显降低 ,并且通过生产示范 。
This paper reports the applied technique of controlling the grubs on the nursery with botrytis fungi Beauveria brongniatii . Controlling the grubs of the northeast giant black chafer Holotrichia diomphalia with 60～90 kg botrytis fungi per hacter, the control effect is 68.8%～86.0%. The mixture of botrytis fungi with insecticide has a synergism. The highest control effect reaches 91%. The authors also put forward five methods of applying fungi for different cultivation forms: spreading fungi on the bedbase of young plants, spreading fungi in the furrows of young plants, spreading fungi on the furrow bedbase of young plants, spreading fungi of furrow intertill, spreading fungi in the growing time of young plants. The control result is 76.1%～83.1%. The injured rate is obviously reduced compared with contrast.
