The proximate mechanism appears to be variation in juvenile hormone (JH) in the stage immediately prior to emergence of the adult form, although the variation in JH may be determined by events ...

The study found that suppressing gut NPF and blocking NPF receptors in the brain that control juvenile hormones both extend ...
