[Juvenile hormone activity in healthy and parasitized adult Anacridium aegyptium (Insecta, Orthoptera) during and after experimental termination of diapause].
The content of juvenile hormone in the haemolymph of Anacridium, normal and infected by Metacemyia (Diptera Tachinidae), has been evaluated by the Galleria bioassay. In all the diapausing locusts, the level of juvenile hormone is very low. It is slightly increased in the males and the parasited animals. In all the locusts,, activated by electrostimulations of the pars intercerebralis, the level of juvenile hormone is high. It is the highest in the infected females with an inhibited vitellogenesis. The allata system cannot therefore be implicated in parasitic castration.
