几种杀虫剂对斯氏线虫的毒力

TOXICITY OF THREE INSECTICIDES TO THE ENTOMOGENOUS NEMATODE STEINERNEMA FELTIAE

通过药剂对线虫的生存力和侵染力影响的试验结果说明,在供试的三种杀虫药剂中,巴丹对斯氏线虫的毒性最大,敌百虫对线虫具有一定的毒性,而氰戊菊酯对线虫几乎无毒牲.巴丹和敌百虫还可导致斯氐线虫处于亚致死状态.

Among three insecticides,Padan (50%SP)Was the most toxic to the nema- tode,Steinernema feltiae Filipjev,which not holy affected the nematode′life, but also lowered its infection to the 3rd-instar larvae of Phyllotreta striolata; toxicity of trichlorphon(90%SP) was lower than Padan;and fenvalerate(20%SP) was safe to the nematode.
