【摘要】 本文就灰豆象生物学进行了试验研究。以白扁豆为饲料饲养观察结果 ,灰豆象在温州市室内条件下每年发生 6代。以幼虫在豆粒内越冬 ,越冬幼虫于翌年 5月上旬羽化为成虫。灰豆象危害各种扁豆、各种豇豆、蚕豆、绿豆、赤豆、大豆等。以嗜食的白扁豆作饲料 ,饲养2～ 3月 ,繁殖倍数分别为 6 2 .7与 1 0 8.7倍 ;饲养 3个月的饲料损失率为 5 5 .5 8%。更多还原

【Abstract】 This paper deals with the biology of Callosobruchus phaseoli.The insect has six generations a year in Wenzhou by artificial rearing with white hyacinth bean(Ines csculent)in the laboratory.It overwinters as larvae inside beans until next early May.This pest damages hyacinth beans,cowpeas,broad bean,mung bean,red bean,soybean and et.al.Lab experiments show that it reproducts 62.7times for 2 months and 108.7times for 3 months raised with white hyacinth bean.The loss rate of feed is 55.58%rearing for 3months.更多还原
