Abstract

We report a case of genetic linkage between the two major loci underlying different wing traits in the two-spot ladybird beetle, Adalia bipunctata (L.) (Coleoptera: Coccinellidae): melanism and winglessness. The loci are estimated to be 38.8 cM apart on one of the nine autosomes. This linkage is likely to facilitate the unravelling of the genetics of these traits. These traits are of interest in the context of the evolution of intraspecific morphological diversity, and for the application of ladybird beetles in biological control programs.

摘要

我们报道了一种遗传连锁情况，在二斑瓢虫（Adalia bipunctata (L.)，鞘翅目：瓢虫科）中，控制不同翅型性状的两个主要基因座之间存在遗传连锁：黑化和无翅。据估计，这两个基因座在九条常染色体之一上相距38.8厘摩。这种连锁可能有助于阐明这些性状的遗传学。在种内形态多样性的进化背景下，以及在瓢虫用于生物防治计划的应用方面，这些性状都备受关注。
