| juvenile hormone |
A chemical produced by the corpora allata, one of the three major insect development hormones, and responsible for determining the type of moult which will occur when one is directed by ecdysone. At high JH blood titre, additional larval or nymphal moults occur; low titre or complete absence of JH causes the pupal or imaginal transformation to occur.
