在25 m3室内测定了含几种拟除虫菊酯的蚊香对致倦库蚊、埃及伊蚊和大劣按蚊的生物学效果。并与日本的淡色库蚊试验结果进行了比较。基于含有dl，d-T80-丙烯菊酯、d，d-T-炔丙菊酯和四甲基环丙烷羧酸甲氧基甲基-四氟苄基酯（K-3050）的蚊香在0.05 - 0.5%（w/w）剂量下在有或没有杀虫剂的情况下的KT 50值（50%击倒时间），四种蚊子物种的拟除虫菊酯敏感性如下：致倦单胞菌对拟除虫菊酯的耐受性是Cx的数倍。p. pallens，Ae.埃及伊蚊的耐受性是Cx的数倍。p. quinquefasciatus和An.大劣犬比Cx更敏感。p.pallens（KT_（50）值约为Cx. p.pallens）。它们的亲和性顺序与拟除虫菊酯相同。含有0.05 - 0.2%（w/w）剂量的d，d-T-炔丙菊酯和K-3050以及2倍于活性成分比例的N-（2-乙基己基）双环-[2，2，1]-庚-5-烯-2，3-二羧酰亚胺作为抑制剂的Moscovirus线圈对Ae高度有效。埃及伊蚊是登革热最重要的传播媒介。
The bioefficacy of mosquito coils containing several pyrethroids were tested in a 25 m3 room against Culex pipiens quinquefasciatus, Aedes aegypti and Anopheles dirus. The test results were compared with tests against Culex pipiens pallens in Japan. Based on the KT50 values (the 50% knockdown time) of mosquito coils containing dl, d-T80-allethrin, d, d-T-prallethrin and methoxymethyl-tetrafluorobenzyl tetramethyl-cyclopropanecarboxylate (K-3050) at doses of 0.05-0.5% (w/w) with or without a synergist, the pyrethroid susceptibility of the four mosquito species was as follows: Cx. p. quinquefasciatus was several times more tolerant to pyrethroids than Cx. p. pallens, Ae. aegypti was a further several times more tolerant than Cx. p. quinquefasciatus, and An. dirus was more susceptible than Cx. p. pallens (KT50 value: about half of Cx. p. pallens). The order of their susceptibilities is common for pyrethroids. Mosquito coils containing d, d-T-prallethrin and K-3050 at doses of 0.05-0.2% (w/w) and N-(2-ethylhexyl)bicycle-[2,2,1]-hept-5-ene-2,3-dicarboxyimide as a synergist at a ratio of 2 times the active ingredient were highly effective against Ae. aegypti, the most important mosquito vector for dengue fever.
