Solution(By Examveda Team)

Insect vector of African sleeping sickness (caused by Trypanosoma gambiense) is Tse-tse flies.
African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.
The tsetse fly, Glossina sp. is the main vector for trypanosomes, the parasites that cause trypanosomiasis. This disease affects both humans and livestock.
