摘　　要：采用水浴加热,研究不同温度(35℃、45℃、55℃、60℃、65℃)下处理不同时间(60 s、75 s、90 s、105 s、120 s)后对小麦粉中的赤拟谷盗幼虫、蛹和成虫的致死作用.研究结果表明,不同处理温度、不同处理时间对赤拟谷盗幼虫、蛹和成虫的致死作用效果差异显著.在处理温度为35℃、45℃时,各个处理时间对赤拟谷盗幼虫、蛹和成虫正常发育没有影响,而在处理温度为55℃以上时对赤拟谷盗幼虫、蛹和成虫具有较强的致死作用.在处理温度为65℃时,处理60 s以上对赤拟谷盗成虫的致死作用效果即达到100%,处理75 s可100%抑制赤拟谷盗蛹正常发育为成虫,处理90 s以上能完全抑制赤拟谷盗幼虫正常发育为成虫.In this paper, we studied the lethal effect of different treatment temperatures （35 ℃,45℃, 55℃, 60℃ and 65 ℃）on the adults ,pupae and larvae of Tribolium castaneum （Herbst） in wheat flour by water bath heating for different times （60 s, 75 s, 90 s, 105 s and 120 s）. The results showed that the lethal effects of the different treatment temperatures and different treatment times on the adults,pupae and larvae of T. castaneum had significant difference. At 35℃ and 45℃ ,treatment time had no influence on the normal development of the adults ,pupae and larvae of T. castaneum. The temperature higher than 55℃ had strong lethal effect on the adults,pupae and larvae of T. castaneum. For the treatment at 65℃ ,the mortality of the adults reached 100% after treatment for more than 60 seconds, 100% pupae could be suppressed from developing into adults after treatment for 75 seconds, and the larvae could be completely suppressed from developing into adults after treatment for 90 seconds.
