用苯嘧磺隆对德国小蠊、德国小蠊、用概率单位法计算LT 50和LC 50。 当杀螟硫磷浓度从1.0%降低到0.05%时，对奥兰多正常品系德国小蠊的LT_（50）为4.47-9.95天。 当达到50%死亡率的时间从6天增加到10天时，对Orlando正常菌株的克草松LC 50从0.267%下降到0.05%。 House of Representatives，DC（HRDC）品系的有机磷和氨基甲酸酯杀虫剂抗性蟑螂对哈甲酮没有抗性;而杰克逊维尔品系在诱饵浓度> 0.1%时具有低水平的抗性，这是由于避免处理过的诱饵。
Hydramethylnon was fed nonchoice to German cockroaches, Blattella germanica (L.), and LT50s and LC50s were calculated by probit analysis. The LT50s for the Orlando normal strain of German cockroach ranged from 4.47-9.95 days as the concentration of hydramethylnon in the bait decreased from 1.0% to 0.05%. The LC50s of hydramethylnon for the Orlando normal strain decreased from 0.267% to 0.05% as the time to achieve 50% mortality increased from 6 to 10 days. The House of Representatives, DC (HRDC) strain of organophosphate and carbamate insecticide resistant cockroaches had no resistance to hydramethylnon; whereas the Jacksonville strain had low-level resistance at bait concentrations > 0.1%, due to avoidance of the treated bait.
