As a test of the hypothesis that adult temperature stress is an important component of natural selection maintaining the α-gpdh polymorphism, we have looked for differential survival among genotypes subjected to (i) heat shock and (ii) cold shock. Factorial ANOVAR, taking account of genotype, sex and temperature-stress indicated that genotype did not contribute to the variance of survival proportion per vial. We have not therefore found evidence to support our hypothesis. Incidental to the above was a significant sex-temperature interaction. Thus, adult females showed higher survival than males under heat stress, while under cold stress, there was no indication of a survival difference between the sexes.
作为一个假设的检验，即成年时期的温度压力是维持α-gpdh 多态性的自然选择的一个重要组成部分，我们已经寻找了在（i）热激和（ii）冷激下，不同基因型之间的生存差异。考虑到基因型、性别和温度应激的析因方差分析表明，基因型并没有导致每个小瓶的存活率比例的差异。因此，我们没有发现证据支持我们的假设。与上述情况相关的是一个显著的性别-温度相互作用。因此，在热应激下，成年雌性的存活率高于雄性，而在冷应激下，两性之间没有显示出存活率差异的迹象。
