With over 1000 species of pests causing losses in both the quantity and quality of stored food, insect contamination poses significant challenges. The present study assesses the efficacy of the combination of λ-cyhalothrin and chlorantraniliprole against four key storage pests-, , , and . Laboratory bioassays demonstrated species-dependent mortality, with and suffering 100% mortality in several tested scenarios. A 90-day persistence trial revealed decreased efficacy over time, especially for (32.0-71.4% at 0 days and 0.0-7.5% at 90 days) and (38.8-82.7% at 0 days and 0.0-12.7% at 90 days) vs. and . Progeny production of and was almost suppressed in persistence trials (0.4 individuals per vial and 1 individual per vial, respectively) after 30 days of storage at the dose of 5 mg/kg wheat. The results highlight the variability in insecticidal performance based on species, dose, exposure, and commodity type, emphasizing the need for tailored pest management strategies in the storage environment.
有1000多种害虫会导致储存粮食的数量和质量损失，昆虫污染带来了重大挑战。本研究评估了高效氯氟氰菊酯和氯虫苯甲酰胺组合对四种主要储粮害虫——、、和的防治效果。实验室生物测定表明死亡率因物种而异，在几种测试情况下，和的死亡率达到100%。一项为期90天的持效性试验显示，随着时间推移效果下降，尤其是与和相比，（0天时为32.0 - 71.4%，90天时为0.0 - 7.5%）以及（0天时为38.8 - 82.7%，90天时为0.0 - 12.7%）。在以5毫克/千克小麦的剂量储存30天后，持效性试验中几乎抑制了和的后代繁殖（分别为每瓶0.4只个体和每瓶1只个体）。结果突出了基于物种、剂量、暴露和商品类型的杀虫性能差异，强调了在储存环境中需要制定针对性的害虫管理策略。
