鸡腿菇生产中高效安全杀虫剂的筛选

Screening of High Efficiency and Safety Insecticides in Production of Coprinus comatus

以鸡腿菇为试材,以农业上广泛应用的敌敌畏、高氯及绿晶为供试药剂,采用平板加药法和杀虫剂灭蝇法对所选药剂进行筛选评估。结果表明:3种杀虫剂对鸡腿菇菌丝生长的影响存在显著差异。敌敌畏对果蝇的杀灭作用强,但同时对菌丝的生长有较强的抑制作用和致畸作用;高氯对菌丝生长抑制作用稍弱,对果蝇的杀灭效果一般;低浓度的绿晶对菌丝生长的抑制作用较小,且对果蝇的杀灭效果明显,可作为高效安全杀虫剂在食用菌栽培中使用。

Taking Coprinus comatus as test material, the effect of dichlorvos, beta-cypermethrin and azadirachtin that widely used in agriculture for hypha growth and the result on drosophila killing were screened and evaluated by disk quantitative medicine and the killing drosophila experiments. The results indicated that three kinds of insecticides had significant differences on hypha growth of Coprinus comatus. Dichlorvos had strong effect on killing drosophila, but it was also an stronger inhibitor and teratogen to hypha growth;the inhibition effect of beta-cypermethrin was relatively weak,and the killing drosophila was not obvious ; the inhibition effect of azadirachtin on the low concentration was small and the killing drosophila was notable,and it may apply to mushroom cultivation as a insecticide with high efficiency and low toxicity.
