杀虫烟剂的研制与应用

目的:开发一种杀虫烟剂,用于国境口岸快速杀虫。方法:参照国家标准及相关文献的报道。结果:杀虫烟剂在常温贮存,对德国小蠊的KT50为8.09～8.32min,48h死亡率为100%;模拟现场对淡色库蚊、德国小蠊和美洲大蠊的2h全部击倒,48h死亡率为100%;现场处理船舶、居民家庭、饭店和集装箱,对蟑螂的灭效为92.01%和100%;大鼠的急性吸入毒性LC50大于5000mg/m3,属微毒类农药,家兔眼刺激为无刺激;烟剂点燃时间为3″～5″、发烟时间为3′5″～3′28″、自燃温度为120.8～125.5℃、燃烧温度为205～210℃、成烟率为85.19～91.85%、吸湿率为0.13%、热储1～2周降解率分别为2.21%,安全性能检测合格。结论:杀虫烟剂杀蟑螂效率高,而且使用简便、安全,性能稳定,对环境无污染。

Development and application of insecticide aerosols

Objective： To develop the killing pest aerosol production which will be used in Chinese frontier. Methods： These methods are refer to Chinese standard methods （GB/T） and some other recognized literatures. Results： With normal temperatures, the KTS0 of killing cockroach aerosol production for Blattella germaniea is 8.09 min-8.32min; the 48h death rate is 100%; at our simulation site, all Blattella germanica, Periplaneta americana or Culex pipiens pallens were be knocked down within 2hr, on-site processing ships, households ,restaurants and container, to eliminate effects of cockroach 92.01%and100% which were all killed within 48h; For the rat acute itthalation toxicity rest, the LD50 exceeded 5000mg/m^3. For the rabbit eye test, it proved to have no irritation. Other safe function items are all eligible; The Aerosol has better capability. The perfectibility is better. The Ignite time is 3see-5sec, send out smoke time is 3min 5sec-28sec. The self-ignite temperature is 120.8℃-125.5℃, burning temperature is 205℃-210℃. The moisture absorption rate is 0.13%, dispel rate is 2.12% at 14 day in hot store up. Conclusions： The aerosol has high kill rate for cockroach, it has convenient handle, safety, performance stabilization, nothing pollution.
