Abstract: 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.
