在一系列的实验中，Lasiserricorne（F.）在30°C下进行。和60%。已经确定，食物短缺阻碍发育，减少未成熟阶段的存活，还降低了所产生的成年体的重量。没有检测到幼虫之间的竞争效应超过和以上所造成的食物短缺。幼虫只在完全没有其他食物的情况下才吃卵和蛹，而且它们似乎不吃彼此。未成熟阶段的表现与产卵时母本的年龄无关。不同个体达到下一阶段所需的时间之间的变化是正偏态的。成年女性体重超过男性，这种体重差异首先发生在第三（倒数第二）幼虫龄期。两性的发育期无显著差异。
In a long series of experiments with Lasioderma serricorne (F.) carried out at 30°C. and 60 per cent. R.H. it was established that shortage of food prolongs development and reduces survival of the immature stages and also reduces the weight of the resulting adults. Competitive effects between larvae over and above those caused by food shortage alone were not detected. Larvae ate eggs and pupae only in the complete absence of any other food, and they did not appear to eat one another. There was no trend in the performance of the immature stages attributable to the age of the female parent at the time of oviposition. Variation between the times taken by different individuals to attain a subsequent stage was positively skewed. Adult females weigh more than males, this difference in weight first occurring during the third (penultimate) larval instar. There were no significant differences in the developmental periods of the sexes.
