摘要： 使用杀虫剂油漆制剂可以改善杀虫剂的滞留性能。本项目选用6种油漆和5种杀虫剂,共配制成46种杀虫油漆配方,并在实验室评价了它们对德国小蠊的毒效和性能。根据筛选结果,研制了“93836”杀虫剂油漆,涂刷在五合板和瓷板(15×15cm)上,在实验室定期测定滞留效果。结果显示:在常温下(28℃)保存104周,KT₅₀为14.65～17.30min,48h死亡率为100%;在高温(50℃)下保存10周,KT₅₀为10.23～12.59min,48h死亡率为100%,证明杀虫剂油漆的滞留效果至少有2年以上,在海军12艘舰船上使用,涂刷1次后,与5艘对照舰船比较,第4个月的相对种群指数(RPI)为8.29,防治效果令人满意。

Abstract: The use of lacquer-based formulation can improved the residual performance of insecticides. The project selected 6 lacquers and 5 insecticides, and 46 lacquer-based formu-lations were prepared. Laboratory evaluation of the toxic effects was made on the German cockroaches. It was after a series of screening that "93836" insecticidal lacquer was developed. This insecticidal lacquer was applied on plywood plates and ceramictile tiles measured 15×15cm with paint brush at 200g/m². Testing results indicated that "93833" had good effect on cockroach for at least 2 years. The KT₅₀ of the testing panels which lasted upto 104 weeks at 28℃ was 14.65～17.30 min and the mortality was 100% in 48 hours. The KT₅₀ of panels which lasted upto 10 weeks at 50℃ was 10.23～12.59, and mortality was 100% in 48 hours. Field study was conducted on the 12 Naval vessels. Results showed that single application of "93833" achieved excellent result in cockroach control. In comparison with 5 control vessels, related population index(RPI) upto 4 months was 8.29.
