摘　　要：为明确玉米象和绿豆象对食料的嗜好性,利用昆虫趋向性和产卵性进行了试验研究。结果表明:玉米象对糯玉米、高粱、小麦的正趋性和危害性明显优于对薏米和普通玉米;且玉米象喜欢选择淀粉含量较高的食料。绿豆象在黑豆、红小豆和绿豆中的产卵量较高,依次为78.75粒、77.75粒、75.75粒;而在大白芸豆上的产卵量为0粒。因此,建议在储粮过程中将淀粉含量较高的储粮分开贮存,以减轻玉米象对储粮的危害;在储藏绿豆时,可将大白芸豆覆盖在其他豆种上,起到隔离防止绿豆象危害的效果。The food preferences and harm of Sitophilus zeamais Motschulsky and Callosobruchus chinensis were studied in this paper. The results showed that the selectivity and harm of S. zeamais to waxy maize, sorghum and wheat were higher than that to coin seed and common corn. The S. zeamais like higher starch food. The egg laying amount of C. chinensis on the black beans, red bean and green bean were higher, which were 78.75 eggs, 77.75 eggs and 75.75 eggs, respectively, but on the great white kidney bean was 0 egg. Therefore, in order to reduce the harm to the corn caused by the two kinds of insect, we proposed that the high content of starch graiv should be stored separately and the great white kidney bean should be used as the cover on the other beans.
