Life History Of Tsetsefly.
Male and female adults mate. Only one egg is retained in the body of the female. The egg later hatches into larva. The larva feeds on the fluid from the milk gland. It stays about 8 days and moults thrice. The female tsetsefly needs three blood meals to complete the development of each larval stage.
After the third moulting, the larva is born in a shady place where the soil is not too dry or loose.
The larva penetrates into the soil and burrows. The integument of the larva quickly hardens to form a dark brown puparium. Inside the puparium, the larva moults to become a puparium. The pupa stays inside the puparium for about 21 days or more depending on the soil temperature and moisture. The pupa moults several times to become a young adult. The young adult climbs be to the surface, dries up it’s wings and moves to a place like forest.
