presence of juvenile hormone secretion of juvenile hormone IDOMAL:0002296 IDOMAL:0002296 Juvenile hormones is released after eclosion and stimulates the devlopment of host-seeking behaviour. Little is known about the regulation of juvenile hormone secretion in mosquitoes. Decapitation immediately after emergence has the same effect on follicle development as allatectomy, which suggests that the brain is involved. The mechanism of release of JH after eclosion does not appear to operate in Aedes aegypti. There is evidence from Aedes aegypti of the ovaries affecting JH secretion. idomal_namespace
