The Indian meal moth (IMM), Plodia interpunctella (Hübner), is an important pest of stored food products. Contact toxicities of 13 insecticides applied to different surfaces were evaluated at registered label and a higher dose for killing adult males. The ultimate objective was to develop attract-and-kill technologies for P. interpunctella. Two-day-old adult males were exposed to treated surfaces for 2.0 s and then paired with virgin females for mating and oviposition over a 24 h period.
Permethrins and pyrethrins (organic pyrethrin and pyrethrin plus a synergist) caused over 70% mortality to males. Oviposition was impacted by these insecticides, while egg hatch was not. A second experiment tested the 8 week residual toxicity of cyfluthrin, permethrin and pyrethrin at label and at a higher dose of 20 g AI L(-1) on five surfaces: plastic-coated paper, metal, painted plastic, unpainted plastic and wood. Permethrin at 20 g AI L(-1) suppressed males at over 80% for up to 8 weeks and retained activity on surfaces made with plastic-coated paper, metal or plastic. Oviposition was variable among treatments. Egg hatch was generally unaffected by treatment.
Effective attract-and-kill surfaces can be developed for killing IMM males and thereby potentially lead to reduced reproduction and, ultimately, population suppression.
印度谷螟（Plodia interpunctella）是一种重要的储粮害虫。本文评估了 13 种杀虫剂在不同表面的接触毒性，包括标签上的注册剂量和更高剂量，以杀死雄性成虫。最终目标是为印度谷螟开发诱捕和杀灭技术。将 2 日龄雄性成虫暴露于处理过的表面 2.0 秒，然后与处女雌性交配和产卵 24 小时。
除虫菊酯和拟除虫菊酯（有机除虫菊酯和除虫菊酯加增效剂）对雄性成虫的致死率超过 70%。这些杀虫剂影响了产卵，但不影响卵孵化。第二项实验测试了高效氯氟氰菊酯、氯菊酯和除虫菊酯在标签剂量和 20 g AI L(-1)高剂量下在五种表面（涂塑纸、金属、涂塑塑料、未涂塑塑料和木材）上的 8 周残留毒性。氯菊酯在 20 g AI L(-1)下可抑制雄性成虫达 8 周以上，超过 80%，并在涂塑纸、金属或塑料制成的表面上保持活性。产卵在处理之间存在差异。卵孵化通常不受处理影响。
可以开发有效的诱捕和杀灭表面来杀死印度谷螟雄性成虫，从而可能减少繁殖，并最终抑制种群。
