Of 10 pyrethroids tested by topical application of male German cockroaches, Blattella germanica (L.), d-phenothrin was the least toxic at 19, 26, or 31 degrees C. lambda-cyhalothrin was most toxic. Pyrethroids with the alpha-cyano moiety (fluvalinate, fenvalerate, cypermethrin, esfenvalerate, tralomethrin, cyfluthrin, and lambda-cyhalothrin) were more toxic than those without this functional group (d-phenothrin, resmethrin, and permethrin). At LC50, toxicity was negatively related to temperature. Temperature-toxicity responses of five of seven alpha-cyano pyrethroids were parallel, possibly indicating qualitatively identical but quantitatively different levels of detoxification enzymes.
通过对德国小蠊（Blattella germanica (L.)）雄虫进行局部施用来测试10种拟除虫菊酯，在19、26或31摄氏度下，右旋苯醚菊酯毒性最低。氯氟氰菊酯毒性最高。带有α-氰基部分的拟除虫菊酯（氟氯氰菊酯、氰戊菊酯、氯氰菊酯、高效氯氰菊酯、四溴菊酯、氟氰戊菊酯和氯氟氰菊酯）比没有该官能团的拟除虫菊酯（右旋苯醚菊酯、苄呋菊酯和氯菊酯）毒性更大。在半数致死浓度（LC50）时，毒性与温度呈负相关。七种α-氰基拟除虫菊酯中的五种的温度-毒性反应是平行的，这可能表明解毒酶的水平在性质上相同但在数量上不同。
