Outline of Final Research Achievements

Genetic and endocrine control of insect hypermetamorphosis was examined for Epicauta gorhami. Larvae showed a long-day photoperiodic response at 25ºC when the food condition is regulated; larvae directly pupated under long-day conditions whereas they enter pseudopupal diapause under short-day conditions. RNA-seq analysis of the larvae that were distined to pupate or enter diapause indicated that gene expression profiles of some genes known as keys for metamorphosis in model insects are different between them.
