应用实验小屋对二氯苯醚菊酯浸泡棉纱门帘防治侵入屋内蚊虫作了田间试验。门帘浸药量为300mg,ai/m~2,取得较满意的毒杀侵入屋内蚊虫的作用。对留存在屋内的三带喙库蚊毒杀死亡率,0～58天内高达90%以上,391～415天内仍可达70%以上。而外逃入窗阱的蚊虫,死亡率很低,0～58天内不到20%。此种门帘对侵入屋内蚊虫的吸血率没有明显影响,也不能减少侵入屋内蚊虫的数量。 Field experiments were carried out using pectin-impregnated cotton yarn curtains to prevent mosquitoes intruding into the house. Curtain dipped amount of 300mg, ai / m ~ 2, to obtain more satisfactory poisoning effect of mosquito intrusion inside the house. The mortality rate of Culex tritaeniorhynchus retained in the house was as high as 90% in 0 ~ 58 days and still up to 70% in 391 ~ 415 days. The mosquitoes fleeing into the window trap have a very low mortality rate of less than 20% within 0-58 days. Such a curtain has no significant effect on the rate of blood-sucking mosquito invaders, nor does it reduce the amount of mosquitoes that invade the house.
