Research Abstract

In the tribe Xyleborini, all species are haplodiploid. The origin of this sex determination mechanism was occurred once in the lineage of Scolytinae. To understand the molecular mechanisms of haplo-diploidy in coleopteran insects, we cloned sex determination genes from several scolytine beetles and established larval RNAi method for these beetles.
