由于乞讨被认为是一种诚实的需求信号，因此，后代向父母乞讨食物的行为受到了广泛关注。虽然在双亲照料中，幼虫的取食频率往往因性别而异，但很少有研究从父母的性别角度来考察幼虫的乞讨行为。本研究以四斑食蚁兽幼虫为对象，探讨其饥饿程度与其选择雌雄亲本作为乞讨对象的关系。我发现N.没有提供的quadripunctatus幼虫增加了他们的乞讨的强度，和幼虫表现出更多的乞讨对他们的母亲，无论他们的饥饿状态。结果表明，当饥饿时，Nicrophorus幼虫会增加其乞讨的强度，并且它们可以识别父母的性别。
The behavior of offspring begging for food from their parents has received much attention because begging is regarded as an honest signal of young’s need. Although the feeding frequency of young insects is often different toward the sexes in biparental care, few studies have examined the begging behavior in light of the sex of the parents. I conducted an experiment to investigate the relation between the degree of hunger in Nicrophorus quadripunctatus larvae and their selection of male or female parents as the target of their begging. I found that the N. quadripunctatus larvae that were not provisioned increased the intensity of their begging, and that the larvae showed more begging toward their mother regardless of their hunger status. The results indicate that Nicrophorus larvae increase the intensity of their begging when they are hungry, and that they can recognize the sex of their parents.
