黑地毯甲虫Attagenus megatoma（F.）（皮蝇科）分离没有营养培养基，在每月的时间间隔从16-33周龄。在饥饿期间，大多数的隔离幼虫有1饥饿诱导的幼虫蜕皮的前5周内。虽然鲜重损失接近45%，在某些年龄段，饥饿的幼虫化蛹与喂养（对照）幼虫隔离期后，长达20周。在饥饿期间幼虫蜕皮的发生一般不影响化蛹的速率，尽管蜕皮增加了体重减轻，并导致雄性和雌性的蛹都大大减小。两种可能的解释同步化蛹在饥饿和喂养的幼虫，这皮蝇进行了讨论：事件触发化蛹可能是编程的幼虫年龄小于16周的信息素机制可能参与。
Larvae of the black carpet beetle Attagenus megatoma (F.) (Dermestidae) were isolated without nutrient medium at monthly intervals from 16-33 wk of age. During the starvation period, most of the isolated larvae had 1 starvation-induced larval molt within the 1st 5 wk. Although fresh weight lossess approached 45% in some age classes, the starved larvae pupated synchronously with fed (control) larvae after isolation periods as long as 20 wk. The occurrence of a larval molt during starvation generally did not effect the rate of pupation, although molting increased the weight loss and resulted in substantially smaller pupae for both males and females. Two possible explanations for the synchronized pupation in starved and fed larvae of this dermestid are discussed: events that trigger pupation may be programmed in larvae younger than 16 wk of age and a pheromonal mechanism may be involved.
