摘　　要：目的研制卫生杀虫微乳剂及对蚊蝇和蟑螂的杀灭效果。方法微乳剂配制采用经验法进行药效筛选试验,杀虫效果按GB13917.1-13917.8-92和GB/T17322.1-1998规定进行试验,毒理学试验按GB/T15670-1995规定进行试验。结果研制出6%卫生杀虫微乳剂,对蚊、蝇和蟑螂室内药效KT50分别为4.16、5.94和7.28 min,24 h死亡率均为100%,模拟现场药效24 h死亡率均为100%,滞留喷洒试验在不吸收、半吸收和吸收3种板面均达到合格指标要求。毒理学试验为微毒、低毒指标,符合毒性要求。结论6%卫生杀虫微乳剂配方科学合理,冷藏热贮稳定性合格,有效期为2年,安全环保,无刺激性,室内外空间喷洒和滞留喷洒药效合格,有开发推广应用前景。Objective To prepare the hygienic microemulsion and study the effect on killing mosquito, fly and cockroach. Methods The preparation of microemulsion adopted experience way to perform the filtration for pharmic effect. Insecticidal effect was tested according to the stipulations in GB13917. 1 - 13917.8 - 92 and GB/T 17322.1 - 1998. Toxicology was tested according to the stipulations in GB/T 15670 - 1995. Results 6% hygienic microemulsion was prepared. The pharmic effects KTs0 was 4. 16, 5.14 and 7.28 min respectively. Mortality 24 h were all 100%. The mortality of field simulated test for pharmic 24 h were all 100%. For residual spraying test, under condition of non-absorbant, half-absorbant and absorbant all reached qualified index. Toxicology test, it＇s little toxical and low toxical, which was up to request of toxicity. Conclusion The formulation of 6% hygienic microemulsion is scientific and reasonable. It＇s up to the standard for both cold storage and hot storage with 2 years validity. It＇s safe, environmental, friendly and no stimulation. It＇s up to the standard for indoor and outdoor spraying. The residual spraying effects are qualified. It has applicable prospect for development and generalization.
