本文研究了甲酸乙酯对面粉中赤拟谷盗不同虫态的熏蒸作用。通过对熏蒸期间熏蒸剂浓度检测,计算浓度时间乘积(CT)计算不同时间下甲酸乙酯对赤拟谷盗各虫态达到99%控制的处理指标(Lct99)。结果表明甲酸乙酯熏蒸能有效防治面粉中的赤拟谷盗各虫态,赤拟谷盗不同虫态对甲酸乙酯的敏感性由强到弱依次为:卵>低龄幼虫>成虫>高龄幼虫>蛹。在23℃条件下处理6h和12h对面粉中赤拟谷盗的Lct99分别为448.42和599.34mg·h/L
Abstract：The purpose of this research is to evaluate the fumigation activity of Ethyl formate against Tribolium castaneum.The Lct99 of T.castaneum was calculated by detecting concentration of Ethyl formate during exposure. The results indicate that Ethyl formate was effective in disinfecting all life stage of T.castaneum in flour,and the sensitivities of life stages of T.castaneum to Ethyl formate,which arranged from strongest to weakest,were egg, low instar larva,adult,high instar larva and pupa.The Lct99 for disinfecting all life stages of T.castaneum in 6 and 12 h at 23℃were 448.42 and 599.34mg·h/L,respectively.
