title: Role of the Corpus Allatum in the Control of Adult Diapause in the Blow Fly, Protophormia terraenovae.
abstract: Adults of the blow fly, Protophormia terraenovae developed their ovaries promptly after emergence under long-day conditions at 25 degrees C, although they entered diapause under short-day conditions at 20 degrees C. Application of a juvenile hormone analog (JHA), implantation of the corpus allatum (CA) from reproductive adults, or transection of the nervus corporis allati induced ovarian development under diapause-inducing conditions. Removal of the CA suppressed ovarian development under diapause-averting conditions, and JHA application induced ovarian development in allatectomized adults. Therefore adult diapause in P. terraenovae is caused by a reduction of juvenile hormone secretion from the CA, and the endocrine activity of the CA is inhibited through a nervous pathway by the brain in diapause adults.
