The current study aimed to study the use of larvivorous fish against larvae of Anopheles gambiae malaria vector in laboratory conditions in Dogbo district in south-western Benin, West Africa. Larvae of Anopheles gambiae s.l mosquitoes were collected from breeding sites using the dipping method in June 2020 during the rainy season in Dogbo district. Alive Hemichromis fasciatus fishes were bought immediately once catched by fishers of Ganvié location in So-Ava district and carried by car from Ganvié location to the Laboratory. Laboratory evaluation for larvivorous efficacy was conducted. The results showed that larvivorous fishes ate more larvae of Anopheles gambiae s.l. when they were unfed than when they were fed. The results obtained after the introduction of unfed larvivorous fishes in glass jars showed high larva-eating capacity of these fishes.
