利用昆虫病原物来控制害虫的危害,是近年来害虫管理上的重要措施.虽然很多昆虫病原物还远不能作为生物杀虫剂或杀虫效果还不能达到完全控制害虫的目的,但可用来提高害虫对化学农药的敏感性(Bcll 和 Mclaughlin,1970;Listov 和 Ncsterov,1976;Rabindra等1988)本文报道了棉铃虫幼虫在感染苏芸金杆菌(BT)后,增加了对化学农药的敏感性.
The use of entomopathogenic agents to control pest damage is an important measure in the management of pests in recent years.Although many insect pathogens are far from being biopesticides or insecticidal, they can not achieve the goal of complete pest control but can be used to improve Susceptibility of pests to chemical pesticides (Bcll and McLaughlin, 1970; Listov and Ncsterov, 1976; Rabindra et al. 1988) This paper reports the susceptibility of cotton bollworm larvae to chemical pesticides after infection with Bacillus thuringiensis (BT).
