摘　　要：采用5点取样法对北京地区夏播小豆田进行了调查,发现绿豆象在小豆鼓粒初期已将卵产到豆荚上,9月上、中旬为产卵高峰期,并逐渐发育成幼虫侵入豆粒中。绿豆象卵在小豆荚上的空间分布型为聚集分布,其聚集原因是由环境因素引起。9月10-15日是控制北京地区夏播小豆田间绿豆象产卵及卵发育的较好时机。Callosobruchus chinensis is the major store pest of adzuki bean. The author investigated the insect in adzuki bean fields through sampling. The results showed that the insect laid eggs on pods at the initial filling stage of grains. The peak ovipositional period covers the first twenty days of September. The eggs then hatched into larvae and intruded into adzuki bean grains. The spatial distribution of the egg-laying pattern was aggregation distribution caused by environmental factors. The best time for controlling egg laying and egg development is Sept 10-15.
