蚕豆象又名豆牛虫,是危害蚕豆的主要害虫。随着今后用地和养地相结合的耕作制度,——(稻、豆)、(棉、豆)的推广,蚕豆播种面积将会逐年扩大,对蚕豆象的防治必须予以足够的重视。笔者对蚕豆象的危害性、生物学特性及防治方法,进行了两年的观察和试验,现将资料整理如下。蚕豆象对蚕豆危害较大,有“十豆九蛀”之称,据1979—1980年3月中旬的多点调查,有虫孔蚕豆一般达37.2—69.7％,个别严重的达83.7％以上。有虫孔蚕豆比无虫孔蚕豆千粒重轻28—33克,产量损失达6—8％,严重的达16％以上。同时,据发芽试验 Broad bean beans, also known as beans, pests, is the main pest endangering beans. With the future system of land use and combination of farming systems, - (rice, beans), (cotton, beans) promotion, broad bean planted area will be expanded year by year, the prevention and control of broad bean elephant must be given sufficient attention. The author of the dangers of Vicia faba, biological characteristics and methods of prevention and control for two years of observation and testing, the data are summarized below. Broad bean like greater harm to Vicia faba, “Wudu bean”, said, according to 1979-1980 in mid-March of the multi-point survey, the general population of wormhole 37.2-69.7%, some serious up to 83.7%. Worm hole worms than non-worm hole beans light weight of 28-33 grams, yield loss of 6-8%, a serious up to 16%. At the same time, according to germination test
