Relationship between Anophelism of Fish Ponds and Malaria Transmission at Lwiro-Katana, Eastern Zaire

Abstract

A study on anopheles larvae population in fish ponds was carried out in 1992 at Lwiro-Katana, South Kivu region, Zaire. The fish ponds serve as the habitat of immature stages of local the malaria vector species, Anopheles gambiae and Anopheles funestus. The larvae of these two spieces together comprise 98.33 percent of all the mosquitoes found in the ponds in contagious distribution and were abundant from February to May. A significant correlation was found between the relative density of malaria vector species in the fish ponds and the number of malaria patients registered at the health centers of Lwiro-Katana.
