The khapra beetle, Trogoderma granarium (Everts), is a highly destructive stored product insect that presents a significant threat to stored bagged grain. Hermetic packaging is designed to maintain the quality and safety of stored grain, while continually protecting the grain from insect infestations during storage. The objective of this research was to evaluate a prototype deltamethrin, all-in-one treated hermetic bag on contact efficacy, larval mobility, and the control of T. granarium in artificially infested wheat. The insecticidal activity of the deltamethrin-treated packaging was tested against larvae and adults of T. granarium through contact bioassays. There was a significant reduction in responsive adults after 5 day and >86% of larvae were unresponsive after 9 d of exposure on the treated bag. Trogoderma granarium movement toward a food bait was <10% after a 24 h exposure on the treated bag compared to ~45% of larvae on untreated bag. Lots of 15 kg of wheat were artificially infested with 100 T. granarium larvae and placed inside treated and untreated storage bags, sealed, and stored in a semi-field warehouse, and observed after 2, 6, and 8-weeks for T. granarium survival and grain quality attributes. The weight and number of insect damaged kernels was lower across all storage intervals for grain held in the treated bags, as compared with control bags. Live adult T. granarium were observed at 2-weeks in treated and untreated bags, but there were no live adults observed after 8-weeks of storage in both bags. The new prototype hermetic bags maintained positive grain qualities, however more information on the hermetic parameters are needed to understand how some individuals survived.

khapra 甲虫Trogoderma granarium (Everts) 是一种极具破坏性的储存产品昆虫，对储存的袋装谷物构成重大威胁。密封包装旨在保持储存谷物的质量和安全，同时在储存过程中持续保护谷物免受虫害。本研究的目的是评估原型溴氰菊酯、一体化处理的密封袋在接触功效、幼虫活动性和对人工感染小麦中的麦粒霉病的控制方面。经溴氰菊酯处理过的包装对谷物 T. granarium幼虫和成虫的杀虫活性进行了测试通过接触生物测定。5 天后有反应的成虫显着减少，在处理过的袋子上暴露 9 天后，> 86% 的幼虫没有反应。与未经处理的袋子上约 45% 的幼虫相比，在处理过的袋子上暴露 24 小时后，谷斑蚴向食物诱饵的运动<10%。取一批15kg小麦，人工侵染100只T. granarium幼虫，分别放入处理过和未处理过的贮藏袋内，密封，半田间仓库保存，2、6、8周后观察T. granarium生存和粮食质量属性。与对照袋相比，在处理过的袋子中保存的谷物的所有储存间隔中，虫害谷粒的重量和数量都较低。活成人在处理和未处理的袋子中在 2 周时观察到T. granarium，但在两个袋子中储存 8 周后均未观察到活成虫。新的原型密封袋保持了良好的颗粒质量，但是需要更多关于密封参数的信息来了解一些人是如何幸存下来的。
