摘要
本文报道了新合成的两种菊醋杀虫活性。经对3种卫生害虫试验，结果表明：氟炔菊酯（PY902）对淡色库蚊幼虫LC50为6．8×10－3ppm；氟烯氰菊酯（PY903）为6．7×10－3ppm；按5mg／m3喷雾，前者对蚊蝇KT50分别是7．0min及6．9min；后者为16．0及12．6min；两者24h死亡率均为100％。两种化合物对蜚蠊亦有较好的杀灭效果。
The present report is about Killing effect of two types of pyrethroid synthesis nearly.The experimental results for three hygyenic insects show that: LC50 of Py902 and Py903 is 6.8 ×10-3ppm and 6.7 ×10-3 ppm for Larve of Culex pipiens pallens. Nespe-Ctively. When sprarying in airat 5mg/m3 KT50 of Py902 is 7.0min arid 6.9min for mosquito and flies. That of PY903 is 16.0 minand 12.6min respectively. The mortalities of 24h are all 100%. The effect of Killing Cockraches isalso better.
