摘  要:
应用林丹烟剂大面积防治兴安落叶松鞘蛾 ,对其寄生蜂种群有显著的副作用 ,可导致寄生蜂总寄生率下降 6 3% ,特别对小蜂类种群影响更大。试验结果看出 ,放烟后第 3年 ,防治区鞘蛾种群数量可回升到接近放烟前的水平 ,而寄生蜂的种群数量却增长不到放烟前的 50 %。放烟不仅可以直接减少寄生蜂的数量 ,还可大量杀伤其中间寄主 ,进而直接影响寄生蜂数量的回升

摘  要:
Effects of aerosol on parasitic wasp were studied in this paper.The experiments illustrated that lindane aerosol could reduce the parasitic rate of wasps to 63%. The amount of pests recovered in the third year after the treatment while the number of parasitic wasps was only 50% of that before using the chemical. Study also conceal that the aerosol can kill interhosts of wasps thus influences the recover of wasp population.
