利用实验小屋对α—氯氰菊酯浸泡棉纱蚊帐(40mg ai/m~2)防治侵入屋内蚊虫进行了连续三个月的观察。结果表明:对中华按蚊毒杀作用稍高于三带喙库蚊,三个月后对中华按蚊的毒杀率仍在90％以上,三带喙库蚊约60％;半闭帐时可降低吸血率,三带喙库蚊约71％,中华按蚊约50％。浸泡蚊帐后大大降低了蚊虫在蚊帐的停落数量,增加了蚊虫的外逃比率,说明α—氯氰菊酯有较强的兴奋驱避作用,实验结果亦显示α—氯氰菊酯浸泡蚊帐育较强的空介毒杀作用。
The use of experimental cabin for mosquito net soaked in alpha-cypermethrin (40mg ai / m ~ 2) to prevent mosquito intrusion into the house for three consecutive months of observation. The results showed that the toxicity to Anopheles sinensis was slightly higher than that of Culex tritavilleensis, the poisoning rate to Anopheles sinensis was still above 90% after three months and about 60% to Culex tritaeniorhynchus; Can reduce the rate of vampire, Culex tritaeniorhynchus about 71%, Anopheles sinensis about 50%. Submerged mosquito nets greatly reduced mosquito net after stopping the number of mosquito nets, an increase of mosquito flight ratio, indicating that the a-cypermethrin strong excitement repellent effect, the results also showed that alpha-cypermethrin mosquito net education stronger disinfection Kill effect.
