| Research Abstract |
Thrips are classified as one of the hemimetabolous species that develop directly from larva to adult, but there are quiescent and non-feeding stages called propupa and pupa between larval and adult stages. Thus, the manner of thrips' metamorphosis is quite different from other hemimetabolous or holometabolous species. The mechanism how thrips' metamorphosis is regulated by hormones has not yet been investigated. In this study, we isolated cDNAs encoding two transcription factors involved in juvenile hormone signaling in two thrips species. From the results of this study, we speculated how thrips' metamorphosis has evolved.
