摘　　要：利用“Y”形嗅觉仪进行室内气味选择试验,测试了嗜虫书虱Liposcelis entomophila性成熟雄虫对5种已有报道的食物挥发性物质的选择性,明确了单一化合物对嗜虫书虱的引诱效果,为食物引诱剂的开发奠定了基础。对筛选的挥发性物质按照不同配方配制两种引诱剂,并在郑州市某成品粮库对两种引诱剂进行了实仓诱捕试验。结果表明,5种挥发性物质对嗜虫书虱均有一定的引诱效果,不同浓度下引诱效果有显著差异(P<0.05),不同浓度挥发物对嗜虫书虱的引诱作用存在剂量反应曲线,说明不同挥发性物质按照一定的比例并且在一定的浓度范围内对嗜虫书虱具有一定的引诱作用。实仓诱捕试验结果表明,两种引诱剂结合锥形诱捕器对嗜虫书虱的诱捕具有显著的效果,其中配方1的引诱效果显著高于配方2(P<0.05)。说明配方1可以作为储粮书虱的引诱剂进行开发和推广。利用两种引诱剂还可以对嗜虫书虱的发生进行监测和预测,同时还可以对嗜虫书虱在粮堆中可能发生的部位进行预测。The selectivity of mature male Liposcelis entomophila on five reported food valatile components was tested out in laboratory with Y-type olfactometer.The attractiveness of a single compound on the L.entomophila was clarified,which provided a basis for the development of food attractants.At the same time,two kinds of lures made by specific components were tested in a warehouse in Zhengzhou.The results of odor selection test showed that all the five chemical components had attractant effects on the tested insects.There were significant differences in the attractant effects and different dose responses to the attractiveness of L.entomophila at different concentrations(P<0.05).The results indicated that the L.entomophila could be attracted by a certain different volatile components according to different ratios within a certain concentration range.The results of trapping experiment in warehouse showed that the combination of two kinds of attractants and conical traps had significant trapping effect on the L.entomophila,which could be used to predict the occurrence time of the L.entomophila,and location of the L.entomophila in grain mass.
