在实验室恒温条件下，测定了谷斑皮蠹的繁殖温度下限。在25 ℃、22.5 ℃、20 ℃和17.2 ℃、70%r.h.条件下，分别观察雌成虫寿命、产卵、卵孵化期和幼虫及蛹发育历期。结果表明，在25度时繁殖缓慢，在22.5度时繁殖非常缓慢，在20度及以下时种群数量下降。因此，将农产品冷却至20摄氏度并保持在该温度或低于该温度是控制该害虫的合理、安全、环境友好的方法。对于新干燥的发芽大麦，结果表明，冷却到25摄氏度将足以防止T granarium种群达到经济重要性的水平。(c)2006年由Elsevier Ltd.出版
The lower temperature limit for breeding of the khapra beetle, Trogoderma granarium,, was determined at constant temperatures in the laboratory. The length of female adult life, oviposition, egg incubation period and duration of larval plus pupal development were observed at 25, 22.5, 20 and 17.2 degrees C, respectively, at 70% r.h. The results show that breeding is slow at 25 degrees, very slow at 22.5 degrees and populations decline at 20 degrees C and below. Thus cooling of produce to 20 degrees C and retention at or below this temperature is a sound, safe, environmental friendly method for control of this pest. For newly dried malted barley, the results indicate that cooling to 25 degrees C would be sufficient to prevent T granarium populations from reaching levels of economic importance.
