德国小蠊（Blattella germanica（L.）（VPIDLS）显示广泛的交叉耐药性，所有拟除虫菊酯时，局部应用于腹部测试。相比之下，当使用表面接触法时，菌株的交叉抗性谱没有延伸到氯氰菊酯和溴氰菊酯（两种典型的II型拟除虫菊酯）。为了理解交叉抗性表达中这种差异的原因，检查了不同的施用方法和毒性标准。局部应用的位置，包括头部和胫骨，对交叉耐药模式的影响很小。我们得出结论，通过表面接触，氯氰菊酯和溴氰菊酯的作用方式与DDT或其他典型的I型拟除虫菊酯不同。
A DDT-resistant (kdr) strain ofBlattella germanica(L.) (VPIDLS) showed broad cross-resistance to all pyrethroids when tested by topical application to the abdomen. By contrast, the strain’s cross-resistance spectrum did not extend to cypermethrin and deltamethrin (two typical Type II pyrethroids) when a surface contact method was used. To understand the cause(s) for such a difference in cross-resistance expression, different application methods and toxicity criteria were examined. Location of topical application, including the head and tibia, had little influence on the cross-resistance pattern. We concluded that, by surface contact, cypermethrin and deltamethrin act in a way atypical of DDT or other typical Type I pyrethroids.
