Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Nematology Summary: This work is dealing with biological control of mosquito larvae. We first started with testing the efficiency of The Louisiana red swamp crayfish, Procambarus clarkii (Gerard, 1852) accidently introduced from USA to Egypt and the cyclopoid copepod, Mesocyclops sp. isolated from Beni Swaif and Kaliobia governorates, Egypt both as predators of Culex quinquefasciatus mosquito larvae. Data for Procambarus clarkii have shown that 4th instar mosquito larvae were the most consumed stage compared to other mosquito instars. Due to the need for animal proteins required in the growth and development of eggs, gravid crayfish females consumed more mosquito larvae than males. Mosquito population densities had positive significant effect on predation rate, with higher mosquito densities, the animal feed on more mosquito larvae. When a mixed diet of fresh vegetables (lettuce) and mosquito larvae were introduced to the crayfish, it depended more on mosquito predation as a source of animal proteins than vegetal food. Data for the cyclopoid copepod have shown that, when 5, 10 and 50 mosquito larvae were used as preys of one female copepod, predation rate was found to be 4.7, 9.1and 11.7 after one day post prey/predator exposure respectively
