蚕豆象(Bruchus rufimanus)是危害蚕豆籽粒的一种害虫。研究其田向分布型,对确定资料代换和相应抽样技术及提高测报质量和防治技术都有重要意义。为此,我们于1982年和1985年对蚕豆象成虫的田间分布型进行了调查,并对抽样方法和抽样数量进行了比较,现将研究结果简报如下。 Bruchus rufimanus is a pest that harms broad bean seeds. Studying its field distribution pattern is of great significance for determining data substitution and corresponding sampling techniques and improving the quality of measurement and control technologies. To this end, we conducted a survey of the field distribution patterns of adults of Vicia faba in 1982 and 1985, and compared sampling methods and sampling numbers. The findings are summarized as follows.
