In an effort to develop a more effective measure for use in emergency control of the dengue vector Aedes aegypti. applications of a combination of a larvicide (Bacillus thuringiensis israelensis [B.t.i.]) and an adulticide (permethrin) were made using a truck-mounted forced-air generator (Scorpion 20) and evaluated in the Dominican Republic. This method has the potential to simultaneously control adults and larvae. In bioassay cages placed in household water containers at the time of application, larval mortalities were 95.1 and 100% for 2 application rates of permethrin mixed with B.t.i. Adult mortalities were not as impressive, probably because of resistance to permethrin. Higher adult mortality in caged specimens (78.5%) and a substantial reduction in the natural population (68.4%) of Ae. aegypti were obtained following a 2.1-g AI/ha application of deltamethrin alone.
为了开发一种更有效的措施用于登革热媒介埃及伊蚊的应急控制，使用车载强制空气发生器（蝎子20型）将杀幼虫剂（苏云金芽孢杆菌以色列亚种[B.t.i.]）和杀成虫剂（氯菊酯）组合应用，并在多米尼加共和国进行了评估。这种方法有可能同时控制成虫和幼虫。在施用时放置于家庭水容器中的生物测定笼中，与B.t.i.混合的两种氯菊酯施用量下幼虫死亡率分别为95.1%和100%。成虫死亡率并不那么显著，可能是因为对氯菊酯产生了抗性。单独施用2.1克有效成分/公顷的溴氰菊酯后，笼中样本的成虫死亡率较高（78.5%），埃及伊蚊的自然种群数量大幅减少（68.4%）。
