摘　　要：研究了在室内条件下用薰衣草精油、罗勒精油熏蒸印度谷螟成虫、幼虫后的效果及虫的活性。采用密闭空气滤纸熏蒸法测定薰衣草精油和罗勒精油对印度谷螟成虫和幼虫的熏蒸作用,分析了薰衣草精油和罗勒精油对印度谷螟成虫、幼虫熏蒸作用的亚致死剂量。罗勒精油对印度谷螟幼虫的熏蒸作用强于薰衣草精油,经时间96 h、浓度为50μL的薰衣草精油和罗勒精油处理后,印度谷螟幼虫的死亡率分别为在92%和100%。薰衣草精油和罗勒精油在2 h下,3.5μL时对印度谷螟成虫的死亡率为100%和83.33%;同样在2 h下,薰衣草精油使用量在3.5μL时,印度谷螟死亡率最高,而罗勒精油使用量在4.5μL时死亡率为99.33%。罗勒精油对印度谷螟幼虫的熏蒸作用显著高于薰衣草精油,而薰衣草精油对印度谷螟成虫的熏蒸作用显著高于罗勒精油。The fumigation activity and effect of adults and larvae of Plodia interpunctella(Hübener)with Lavandula angustifolia Mill oil and Ocimum basilicum oil on under indoor conditions was studied.The fumigation effect of Lavandula angustifolia Mill oil and Ocimum basilicum oil on adults and larvae of Plodia interpunctella(Hübener)was determined by a closed air filter paper fumigation method.Sublethal doses of Lavandula angustifolia Mill oil and Ocimum basilicum oil on fumigation of adults and larvae of Plodia interpunctella(Hübener)were analyzed.The results showed that the fumigation effect of Ocimum basilicum oil on Plodia interpunctella(Hübener)larvae was stronger than that of Lavandula angustifolia Mill oil.After treatment with Lavandula angustifolia Mill oil and Ocimum basilicum oil at a concentration of 50μL for 96 h,the mortality rates of Plodia interpunctella(Hübener)larvae were 92%and 100%,respectively.The mortality rates of adults of Plodia interpunctella(Hübener)treated with Lavandula angustifolia Mill oil and Ocimum basilicum oil were 100%and 83.33%at 3.5μL for 2 h;When both treated for 2 h,3.5μL of Lavandula angustifolia Mill oil led to the highest mortality rate of Plodia interpunctella(Hübener),while 4.5μL of Ocimum basilicum oil only caused 99.33%of mortality rate of Plodia interpunctella(Hübener).The study showed that the fumigation effect of Ocimum basilicum oil on Plodia interpunctella(Hübener)larvae was significantly higher than that of Lavandula angustifolia Mill oil,and the fumigation effect of Lavandula angustifolia Mill oil on Plodia interpunctella(Hübener)adults was significantly higher than that of Ocimum basilicum oil.
