雌性成虫和它们的后代--甘肃叶螨和麻黄叶螨--共同生活在同一片叶子上。为了弄清雌性成虫的存在是否会影响后代的表现(母体效应)，我们检测了与雌性成虫生活在一起或没有雌性成虫生活的幼虫的表现指数(成熟后的繁殖力)。在这两个物种中，雌性成虫的存在都降低了幼虫的表现指数。甘蔗黄粉虫的作用比麻黄粉虱更明显。另一方面，甘蔗黄粉虫雌成虫早于麻黄粉虱雌成虫从受侵染的叶片上散布。本文还讨论了母体效应与甘蔗黄粉虫和麻黄粉虱传播能力之间的关系。
Female adults and their offspring of tetranychid mites, Tetranychus kanzawai and T. urticae, live together on the same leaf. To clarify whether the presence of female adults affects the performance of offspring (maternal effect), we examined the performance index (fecundity after maturation) of juveniles that had lived with female adults, or without them. In either species, the presence of female adults reduced the performance index of juveniles. The effect of T. kanzawai was more conspicuous than that of T. urticae. On the other hand, female adults of T. kanzawai dispersed from an infested leaf earlier than those of T. urticae. The correlation between the maternal effect and dispersal capacity of T. kanzawai and T. urticae was discussed.
