Vitellogenesis
From Wikipedia, the free encyclopedia
Vitellogenesis (also known as yolk deposition) is the process of nutrients being deposited in oocytes, a female germ cell involved in reproduction. It starts when the fat body stimulates the release of juvenile hormones and produces vitellogenin protein. With insects, vitellogenesis can be stimulated by injection of Juvenile hormone into immature female cockroaches and mature male cockroaches.
In mosquitoes infected with Plasmodium, vitellogenesis may be manipulated by the parasites to reduce fecundity (Hurd, 2003).
