Neurotropic effect of juvenile hormone III in larvae of the cockroach, Periplaneta americana.
Juvenile hormone III and juvenile hormone analogs (methoprene, farnesyl methyl ether) cause a short-term depression of spike activity in last instar larvae of the cockroach Periplaneta americana, specifically in the prothoracic gland nerves, both in vivo and in vitro. The decreased nervous activity in the prothoracic gland nerves leads to decreased ecdysteroid secretion by the prothoracic gland.
