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20%。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。

Abstract: 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/m2,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/m2,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.
