| Research Abstract |
Diapause controlling mechanisms by neurosecretory cells in the pars intercerebralis and pars lateralis were examined in the blow fly Protophormia terraenovae. FMRFamide, of which immunoreactivity was observed in the pars latelaris and the corpus allatum, showed week inhibitory effects on juvenile hormone production by the corpus allatum. Ecdysteroid titers and yolk protein gene expression were low under diapause conditions compared with nondiapause conditions. Removal experiments suggest the pars intercerebralis is important to control yolk protein expression but not ecdysteroid titers under nondiapause conditions
