透明状水基型杀虫喷射剂的研究

Study on transparent water sprayers

目的 研究药效与乳化性能稳定的透明状水基型杀虫喷射剂。方法 采用冷、热贮存和自然室温存放相结合的方法进行乳化稳定性观察和药效试验。结果 本次研制的透明状水基型杀虫喷射剂,新配制和冷(0℃)、热(54℃)贮存 4周室内药效测定KT50 (min),对家蝇依次为 2. 21, 2. 05, 2. 01, 2 .54和 3. 11min;对致乏库蚊依次为 2 .54, 2 .50, 2 .83, 2. 35和 3 01min;对德国小蠊依次为 3 .45, 3. 35, 3. 72, 3. 87和 4. 01min。自然室温存放 2.年的室内药效测定KT50 (min),对家蝇依次为 2 . 11和 2. 85min; 对致乏库蚊依次为 2 .34和3 75min; 对德国小蠊依次为 3. 50和 4 .06min。室内和模拟现场药效测定的死亡率均为 100%。结论 本次研制的配方组分和选用乳化剂科学合理,药效和乳化性能稳定,对昆虫死亡率高,能保证 2年的有效期,适宜于室内空间喷雾,与脱臭煤油作溶剂的气雾杀虫剂相比较,具有环保和经济意义,值得推广应用。

Objective To study the effic acy of transparent water sprayers with stable property. Methods Storing the sprayers at high and low tempreture and o bserving the stablity of emulsifying. Results Put the sprayers at the tempreture of 0 ℃ and 54 ℃ for 4 week respectively,the KT 50 of Musca domesticawere 2.21,2.05 ,2.01,2.54 and 3.11 min respectively.The KT 50 of Culex pipiens qui nquefasiatuswere 2.54,2.50,2.83,2.35 and 3.01 min respectively.The K T 50 of Blattella germarnica were 3.45,3.35,3.72,3.87 and 4.01 min respectively.If put it at the natural tempreture for 2 years and test it’s efficacy.The KT 50 of Musca domestica were 2.11 and 2.85 min. Th e KT 50 of Culex pipiens quinquefasiatus were 2.34 and 3.75 min.The KT 50 of Blattella germanica were 3.50 and 4.06 min.The mortality was 100% in the room and mimic spots.Conclusion The insecticide which had reasonable components was suitable for use.It had good efficacy against insects and could be useful in 2 years.It was environment protecting and should be applied broadly.
