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 ,验证了其防治效果
Reported the use of Beauveriabrongniatii to control nuisance underground pests. The control of Holotrichiadiomphalia larvae per hectare was 60 ~ 90kg, and the control effect was 6 8.8% ~ 86.0%. Beauveria bassiana mixed with chemical pesticides have a synergistic effect, the control effect of up to 91%. At the same time, according to different cultivation methods of nursery, this paper put forward five kinds of germicidal methods, such as bed-based germination, seedling ditch germicidal, bed-type germplasm, furrow cultivation, seedling growth, The results showed that the control efficacy of the other four kinds of bacteria was 76.1% -83.1%, the insect population and seedling damage rates were significantly lower than those of the control, and through the production demonstration, the control effect was verified
