摘　　要：以红枣作饲料,室温下在相对湿度75%,光照L∶D=14∶10,强度3500lx条件下,对咖啡豆象2代进行了实验室驯化培养。结果表明,咖啡豆象在贵阳地区年发生3～4代,少数发生5代。多以幼虫越冬,极少见蛹越冬,未发现库房有成虫越冬,完成一个生活周期约需42.3d。并描述了各虫态形态结构特征及其生活习性。The second generation of Araecerus fasciculatus was fed by red jujubes under the condition of 75% relative humidity, L ： D=14 ： 10, 3 500 lx and room temperature to know its occurrence, damage and life history in Guiyang. The results showed that there were normally 3-4 generations in a year and 5 generations in a special year, the overwintering of Araecerus fasciculatus depended on its larvae, the adults were not found in warehouses in winter, and its life cycle needed about 42. 3 d. The paper introduced morphological structural characteristics and life habits of its different pest development periods.
