摘要: 作者于1994年在海南岛石山地区埃及伊蚊种群密度高峰期,应用苏云金杆菌H-14块状缓释剂(剂量:0.0005%),对家庭积水容器中埃及伊蚊幼虫进行了现场毒效研究。结果显示,投药后1个月室内幼虫密度布雷图指数从投药前的123.26降至2.56,最高下降率97.42%;投药后3个月室外布雷图指数从投药前的136.11降至3.33,最高下降率为97.13%;投药后70天埃及伊蚊成蚊相关密度指数为0.044,下降率达95.60%,有效地控制了该蚊高峰期种群密度。

Abstract: The paper reported the study on the toxicological effect of Bacillus thuringiensis H-14 lump-slow-released reagent against Aedes aegypti's larvae in water containers of households during the peak period of Aedes aegypti's density in Shishan area of Hainan Island in 1994.The Breateau index of the indoor larvae decreased from 123.26(before using the reagent) to 2.56,the highest decreased rate was97.42%.Three months after using it,the Breteau index of the outdoor larvae decreased from 136.11 to 3.33,the highest decreased rate was 97.13%.70 days after,the relevent density index of Aedes aegypti's adults was 0.044,the decreased rate reached 95.60%.Therefore,the reagent controlled Aedes aegypti's density effectively in its peak period.
