用球形芽孢杆菌Ts—1冻干菌粉,对国内10种蚊幼虫生物测定的结果表明,不同蚊种之间敏感性有很大差异。库蚊属蚊虫(特别是淡色库蚊和致倦库蚊)对Ts—1敏感性很高,按蚊其次,而伊蚊属除东乡伊蚊外对Ts—1均不敏感。此外,同一蚊种不同地理株之间,对Ts一1的敏感性也有显著差异。 The results of bioassay of 10 species of mosquito larvae in China by using B.subtilis Ts-1 freeze-dried powder showed that the sensitivity of different species of mosquitoes varied widely. Culexids mosquitoes (especially Culex pipiens pallens and Culex quinquefasciatus) were highly susceptible to Ts-1, followed by Anopheles mosquitoes, while Aedes mosquitoes were not sensitive to Ts-1 except Aedes albopictus. In addition, there is also a significant difference in the sensitivity of Ts-1 between the different geographical strains of the same mosquito species.
