长效浸帐剂浸泡蚊帐防治侵入实验小屋蚊虫的研究

1990年0～3月,在扬州市郊用特建的实验小屋,以牛为引诱动物,进行了长效浸帐剂对侵入实验小屋蚊虫毒杀和兴奋驱避作用的研究。按80mg,ai/m~2处理1～80天后,结果表明对当地主要蚊种中华按蚊和三带喙库蚊均有较好的毒杀作用,其总平均死亡率分别为79.1%和53.6%。结果还表明,侵入处理小屋蚊虫数比对照小屋减少46.3%,处理小屋蚊虫平均窗阱外逃率76.4%,与对照小屋相比有显著性差异(P<0.01),说明长效浸帐剂浸泡蚊帐,对蚊虫具有兴奋驱避作用。

Studies on the mosquito net treated with insecticide in long acting netimpregnating formula to control the mosquito invading into the experiment hut

With the luring cow we carried out a study on the deadly poisonous and excito-repellent effect of the mosquito net treated with insecticide in long acting net-impregnating formula on the mosquito invading into the specially constructed experimental hut in the surburb of Yangzhou City from June to September of 1990. From 1-80days after treatment in 80mg ai/m~2, the results showed that the treated mosquito net played an ideal role in the controlling of the local main species An. sinensis and Cx. tritaeniorhynchus, and the total mean mortalities during this period were 79.1% and 53.6% respectively. It was also revealed that the number of the mosquitoes invading into the treated hut reduced for 46.3% compared with that observed in control hut. The rate of mosquito flying out of the hut window was much higher in treated hat (76.4%)than that in the control hut (52.6%) (P<0.01), which proved that the long acting net-impregnaing formula has an excito-repellent effect on mosquitoes.
