摘要
研究了 7种常用化学杀虫剂对苏云金杆菌芽孢及伴胞晶体的影响及作用 ,结果表明 ,常用浓度下 ,2 .5 %溴氰菊酯乳油、4 8%毒死蜱乳油对苏云金杆菌芽孢及伴胞晶体无影响 ,可与苏云金杆菌制剂事先做成混剂 ;4 .5 %高效氯氰菊酯乳油、2 .5 %高效氯氟氰菊酯乳油、2 0 %灭多威和 4 0 %辛硫磷在短时期内对芽孢及伴胞晶体无明显影响 ,可与苏云金杆菌制剂现混现用 ;80 %敌敌畏乳油(5 0 0倍稀释 )对苏云金杆菌伴胞晶体有明显损伤作用 。
The effects of seven chemical insecticides on CH strain were reported. The results of the laboratory study showed that 2.5% deltamethrin EC, 48% chlorpyrifos EC had no harmful effects and they can be made as composite preparation with Bt, 4.5% beta cypermethrin EC, 2.5% lambda cyhalothrin EC, 20% methomyl EC and 40% phoxim EC had weak harmful effects on Bt spore and they can be tank mixed with Bt for use. 80% dichlorvos was very harmful to parasporal crystals. SDS PAGE analysis and bioassay also showed the same results.
