(E)-1-Nitropentadec-1-ene (NPE), the main component of the defense secretion of Prorhinotermes simplex soldiers, is toxic to both insecticide-susceptible (S) as well as to insecticide-resistant (R) strains of the house fly, Musca domestica. The LD50 is 11.7 mu g/female fly for the S strain and 9.7 mu g for the R strain. The same efficacy of NPE on R and S strains indicates a different mechanism of action compared to conventional chlorinated, organophosphorus, and pyrethroid insecticides. Termite nestmates are protected against NPE by a specific detoxification mechanism, 1-Nitropentadecane, the detoxification product of NPE is nearly nontoxic to house flies, and doses up to 160 mu g/fly caused only very low mortality.

甲烷盾 (NPE),即主甲虫 prorhinotermes simplex 数兵的防御分泌,毒性对易sect杀的普通型 (S) 以及抗sect杀的纯合型 (R) 的果蝇 musca domestica 均有效。LD50 为 S 种群 11.7 μg/雌蝇、R 种群仅 9.7 μg。NPE 对 R 和 S 的同样疗效表明,其作用机理与现Using 的
