摘要通过在第一次繁殖时去除成虫对，并允许它们再次繁殖，研究了埋葬虫Nicrophorus quadripunctatus亲代照料的生理成本和亲代照料对幼虫生长的必要性。当在第一离合器的阴影之后中断再现时，第二离合器的数量和质量不会随着稍后执行中断而减少。这些结果表明，父母照顾的生理成本相对较小。孵化后1天或更短时间的父母照料对子代幼虫的生长是必要的。孵化后一天以上的父母照顾既不影响后代幼虫的生存也不影响其生长。此外，后代幼虫与雄性或雌性亲本正常生长。然而，所有的父母女性和大多数男性留在他们的后代，直到幼虫完成喂养。N.将沿着讨论quadripunctatus的成本和效益。
Abstract The physiological cost of parental care and the necessity of parental care for larval growth were examined in the burying beetle, Nicrophorus quadripunctatus, by removing adult pairs during the first reproduction and allowing them to reproduce again. When the reproduction was interrupted after hatching of the first clutch, the number and mass of the second clutch did not decrease as the interruption was performed later. These results demonstrated that the physiological cost of parental care was relatively small. The parental care for one day or less after hatching was necessary for the growth of progeny larvae. Parental care later than one day after hatching influenced neither survival nor growth of progeny larvae. Moreover, progeny larvae grew normally with either a male or female parent. Nevertheless, all parental females and most males stayed with their progeny until the larvae finished feeding. The evolution of parental care in N. quadripunctatus will be discussed along with both its cost and benefit.
