Insect survival after exposure to 0 °C for 7 days was examined in laboratory bioassays for control of adults of six major stored-product beetle species, Oryzaephilus surinamensis (L.), the sawtoothed grain beetle, Cryptolestes ferrugineus, (Stephens), the rusty grain beetle, Dermestes maculatus DeGeer, the hide beetle, Sitophilus oryzae (L.), the rice weevil, Tribolium castaneum (Herbst), the red flour beetle, and T. confusum Jacquelin DuVal, the confused flour beetle In this test there were four different acclimation treatments, insects that had been subjected to a pre-acclimation period to 0 °C, a post-acclimation period, both a pre and post-acclimation period, and adults that were not acclimated. Insect survival for all species except S. oryzae was not affected by the exposure to 0 °C, regardless of the acclimation scenario. In contrast, exposure to 0 °C drastically reduced survival of S. oryzae. Moreover, adults that were exposed to the post-acclimation only and un-acclimated adults had lower survival rates than those that had either exposure to pre-acclimation, or to both pre- and post-acclimation. Results of this experiment show that acclimation played a limited role in adult survival of five of the six tested species, and that exposure of adults to 0 °C for 7 d had no effect in survival of these species as well.

降温降温:温度逐渐变化后,存储的昆虫的差异反应。

在实验室生物测定法中,暴露于0°C 7天后的昆虫存活率用于控制六种主要储藏甲虫,稻米甲虫,锯齿状甲虫,铁锈菌(Stephens),生锈的成虫的成虫谷物甲虫,Dermestes maculatus DeGeer,生皮甲虫,米叶Sitophilus oryzae,稻象鼻虫,Tribolium castaneum(Herbst),红色面粉甲虫和T. confusum Jacquelin DuVal,混淆的面粉甲虫不同的适应性处理,适应前的温度为0°C,适应后的时间(适应前和适应后的时间)以及未适应的成虫。不论适应环境如何,除了米曲霉以外,所有其他物种的昆虫存活率都不受暴露于0°C的影响。相反,暴露于0°C大大降低了米链霉菌的存活。此外,仅接受适应后和未适应的成年人的成活率要低于适应前或适应后的成活率。该实验的结果表明,适应对六个受测物种中五个中的五个在成年存活中的作用有限,并且成年暴露于0°C达7 d对这些物种的存活也没有影响。
