由于化学杀虫剂的各种弊端,对物理高温杀虫方法也进行了试验。红外辐射将小麦温度升到57,65℃,暴露32、40秒可100％的杀死12种储藏物甲虫。通过红外辐射,小麦温度升到48.6℃可杀死99％的米象,93％的谷蠹。在55.6℃下,3分钟内可杀死95％的谷蛾。EVans曾总结了致死害虫的高温极限,即米象和谷象成虫分别在49、54℃,180 Because of the various disadvantages of chemical pesticides, physical high temperature insecticidal methods have also been tested. Infrared radiation raises the temperature of the wheat to 57,65 ° C, exposing 32,40 seconds to 100% killing 12 stored beetles. By infrared radiation, raising the wheat temperature to 48.6 ° C can kill 99% of the rice elephants, 93% of the valley beetles. At 55.6 ° C, 95% of the moth can be killed in 3 minutes. EVans had summed up the high temperature limit of lethal pests, namely, rice and valley elephants were 49,54 ℃, 180
