However, little is known about how this cooperative control is terminating larval dia- pause especially in the bamboo borer, Omphisa fuscidentalis. In both in vivo and in vitro OPEN ACCESS experiments, we here measured the expression levels of genes which were affected by Citation: Suang S, Manaboon M, Singtripop T, juvenile hormone analogue (JHA: S-methoprene) and 20-hydroxyecdysone (20E) in dia- Hiruma K, Kaneko Y, Tiansawat P, et al.
