蚕豆象是冬季绿肥作物蚕豆的主要害虫。棉花蚕豆轮作是用地与养地结合的一种较好的耕作制度。随着棉花蚕豆轮作面积的逐渐扩大,我县防治蚕豆象的问题也逐渐突出起来。为此,我们于1979—1980年对蚕豆象的危害性、生物学特性及药剂防治进行了观察研究。 Broad bean like winter green manure is the main pests of beans. The cotton broad bean rotation is a good farming system combining land use with raising land. With the gradual expansion of the cotton broad bean rotation area, the problem of preventing and controlling Vicia faba in our county is also gradually highlighted. Therefore, we observed and studied the harmfulness, biological characteristics and drug control of Vicia faba in 1979-1980.
