摘　　要：明确绿豆象最耐受高温的虫态,获得该虫态完全防控温度和时间,为防治仓储绿豆象提供理论支撑。试验选择35、45、55℃3个温度对绿豆象的卵、幼虫、蛹、成虫分别处理30、60、90、120、150、180 min,测定不同温度条件不同处理时间后绿豆象各虫态的死亡率。结果显示:4种虫态中耐热性最强的虫态为绿豆象蛹期,绿豆象蛹期经55℃处理150 min后死亡率达100%。因此,利用高温方法防治仓储绿豆象是可行的。To obtain the temperature and time of the total control of Callosobruchus chinensis, the most tolerated high temperature was tested. We selected 35, 45 and 55℃ to treat the eggs, larvae, pupa and adults of C. chinensis for 30, 60, 90, 120, 150 and 180 minutes, respectively. The mortality rates of C. chinensis after different treatments were determined. The results showed that the most heat-resistant insect state of C. chinensis was the pupa stage. After treatment of 150 min at 55℃ during the pupa stage, the mortality rate of the C. chinensis reached 100%. Therefore, it is feasible to use high temperature to prevent and control C. chinensis in storage.
