The susceptibility of field collected Aedes aegypti larvae was evaluated in terms of median lethal time (LT50) and final mortality, when treated with temephos, Bacillus thuringiensis var israelensis as well as mixtures of these two agents. Third instar larvae were shown to be more susceptible than early and late fourth instar ones to the entomopathogen. Survival of some individuals when exposed to temephos suggest possible resistance. Temporal synergism in early fourth instar larvae was detected when they were exposed to mixtures of Bti-temephos. The possibility of this integrated treatment is commented on.
对野外采集的埃及伊蚊幼虫，在用杀螟硫磷、苏云金芽孢杆菌以色列变种以及这两种药剂的混合物处理时，根据半数致死时间（LT50）和最终死亡率评估其易感性。结果表明，三龄幼虫比四龄初期和末期幼虫对昆虫病原体更敏感。一些个体在接触杀螟硫磷时存活下来，表明可能存在抗性。当四龄初期幼虫接触Bti-杀螟硫磷混合物时，检测到了时间协同效应。文中对这种综合处理的可能性进行了评论。
