Hassell和Huffaker 1证明了面粉蛾Anagasta kuehniella（Zeller）种群数量的一些密度依赖性调节。新孵化的幼虫2之间的战斗有助于调节该物种的数量，但不是唯一的控制机制：史密斯3表明，从第一龄末开始的拥挤导致成虫出现延迟和体重减轻。由于较小的蛾产卵较少，这两种效应都将有助于后代的密度依赖性数量调节。我在这里描述一个机制，可以带来这些影响。因此，我们认为，A. kuehniella，当它们相遇时，从它们的下颚腺分泌物的滴存款在基质上;和其他末龄幼虫对这种分泌物的反应不仅导致A. kuehniella在有限系统中（如史密斯3所研究的），而且在该系统内个体分散的控制中。
Hassell and Huffaker1 demonstrated some density-dependent regulation of numbers in populations of the flour moth, Anagasta kuehniella (Zeller). Fighting between newly hatched larvae2 contributes to the regulation of numbers in this species but is not the only controlling mechanism: Smith3 showed that crowding from the end of the first instar onwards led to delayed emergence of adults and a reduction in body weight. Since smaller moths lay few eggs4, both these effects would contribute to the density-dependent regulation of numbers in succeeding generations. I describe here a mechanism which could bring about these effects. I suggest that last-instar larvae of A. kuehniella, when they meet, deposit on the substratum drops of secretion from their mandibular glands; and that the response of other last-instar larvae to this secretion results not only in the regulation of the total numbers of A. kuehniella in a finite system (as studied by Smith3), but also in the control of the dispersion of individuals within that system.
