| 摘 要： | 苏云金杆菌在非致死剂量下对棉铃虫有强的抑食作用 ,且随着浓度的增加 ,抑食作用有进一步加强的趋势。棉铃虫取食刺激剂不仅对棉铃虫具诱引作用 ,可增加幼虫的取食时间和取食量 ,而且可减轻苏云金杆菌对棉铃虫的抑食作用。苏云金杆菌浓度越低 ,取食刺激剂的效果越好。非选择性实验中 ,加入取食刺激剂可使苏云金杆菌致死中浓度降低 4 1%。但在选择性实验中 ,幼虫死亡率无显著提高。

| Abstract: | Bacillus thuringiensis (Bt) was noticed to be highly deterrent to the feeding of Helicoverpa armigera larva when incorporated into diets,even at the non\|lethal dosage.As the dosage of Bt increased,the deterrence showed a tendency of elevation.Feeding stimulant,FS\|1 could attract larvae for feeding,and increase larval feeding time and consumption.Addition of 1% (v/v) FS\|1 could alleviate the deterrent effect of Bt,especialy in low concentration.In no\|choice test,it was observed that while 1% (v/v) FS\|1 was added,LC\-\{50\} of Bt underwent a 41% decrease,but in the choice test,the mortality of larvae was not significantly enhanced. |
