摘　　要：目的 :评价必克幼和生物蛙灭蚊幼效果 ,探讨灭蚊幼效果综合评价方法。方法 :实验室和现场试验调查2种方法。结果 :从现场试验来看 ,必克幼在 5ml m2 的剂量下 ,第 3d蚊幼密度下降达 97.5 % ,蚊蛹密度下降率达92 .7%。另外从 5、7、15d观察结果看 ,蚊幼密度下降率始终保持在 97%以上。生物蛙在 10ml m2 的剂量下 ,第 3d蚊幼密度出现 96%的下降率 ,而蛹的下降率较低 ,仅为 2 0 %。但 5～ 15d后的结果逐渐接近了必克幼。从实验室结果看 ,与现场试验结果相吻合。结论 :2种制剂对蚊幼均具有明显的杀灭作用 ,前者效果好于后者。Objective: To appraise the effect of BACTIVEC and GRISELESF for killing mosquito larvae and study the best way to appraise. Methods: The effect of two biotic pesticides for killing mosquito larvae was tested by the locale and laboratory tests, To observe the mosquito larvae and pupae density degression rate. Results:In the locale, after spraying 3rd days, for BACTIVEC 5 ml/m 2, the density degression rate of the mosquito larvae and pupae was 97.5 % and 92.7 %. After 5th,7th, and 15th day, the density degression rate was usual kept up over 97%. Another, for GRISELESF,10 ml/m 2, after 3rd day, the density degression rate of mosquito larvae was 96%,and the rate of pupae was only 20%. But 5 to 15 days later, the effect of control pupae by GRISELESF was approached to BACTIVEC. The results of labortory was similar to locale. Conclusion: The effects of both biotic pesticides were noticeable to control the mosquito larvae,and the former outbalanced the latter.
