奋斗呐对三个蚊种的毒效试验

The Experimental studies on Toxic efficacy of Fendona against three kinds of Mosquitoes

奋斗呐对三个蚊种幼虫、成虫毒效测定,表明均有较强的毒杀作用。幼虫以三带喙库蚊最敏感(LC_(50) 1.63×10^(-4)ppm),白纹伊蚊最差(LC_(50) 1.75×10^(-2)ppm);成蚊以白纹伊蚊最敏感,三带喙库蚊次之,淡色库蚊最差。但三者差异不显著,KD_(50)分别是0.01996、0.02458、0.0616g/m^2。

The determinations of toxicity of Fendona against larvaes and adults of three kinds of Mosquitoes showed that Fendona can kill effectively the larvaes and adults of mosquitoes. For the larvaes, the Culex tritaeniorhychus was the most sensitive to Fendona (LC_(50) 1.63×10^(-2)ppm) and the Aedes albopictus was the last one(LC_(50) 1.75×10ppm). As to the adult, the most sensitive was Aedes albopictus(KD_(50) 0.01996g/m^2)and the most insensitive was Culex pipiens pallens(KD_(50) 0.0616g/m^2) , there was no significant difference between Culex trilaeniorhychus (KD_(50) 0.02458g/m^2) and Aedes pipiens pallens.
