Sex-determining mechanisms appear to be very diverse in invertebrates. Haplodiploidy is a widespread mode of reproduction in insects: males are haploid and females are diploid. Several models have been proposed for the genetic mechanisms of sex determination in haplodiploid Hymenoptera. Although a one-locus multi-allele model is valid for several species, sex determination in other species cannot be explained by any of the existing models. Evidence for and predictions of two recently proposed models are discussed. Some genetic and molecular approaches are proposed to study sex determination in Hymenoptera.
性别决定机制在无脊椎动物中似乎非常多样。单倍二倍体是昆虫中一种广泛存在的繁殖方式：雄性为单倍体，雌性为二倍体。针对单倍二倍体膜翅目昆虫的性别决定遗传机制，已经提出了几种模型。尽管单基因座多等位基因模型对几个物种有效，但其他物种的性别决定无法用任何现有模型来解释。本文讨论了最近提出的两种模型的证据和预测。还提出了一些遗传和分子方法来研究膜翅目昆虫的性别决定。
