Description
PTTH was one of the earliest hormones discovered in
insects. PTTH regulates insect molting and metamorphosis
by promoting the biosynthesis and release of the molting
hormone ecdysone from the prothoracic glands.

Biological functions
The primary function of PTTH is to promote the biosynthesis
of the molting hormone ecdysone in the prothoracic
glands in response to environmental stimuli. This is
best demonstrated by its regulatory role in pupal diapause;
for example, in the cabbage army moth Mamestra
brassicae, the hemolymph PTTH titer is reduced during
the diapause period, but it is released into the hemolymph
to promote ecdysone biosynthesis when the environmental
condition allows for adult development.
