AB  - BACKGROUND: In a context of increasing resistance of both vectors toward main 
      classes of insecticides used in public health and parasites toward anti-malarial 
      drugs, development of new and complementary molecules or control approaches is 
      fundamental to achieve the objective of controlling or even eliminating malaria. 
      Concerning vector control, the sterile insect technique and other genetic control 
      approaches are among promising complementary tools in an integrated management 
      strategy for malaria control. These approaches rely not only on a good 
      understanding of vector biology (especially during larval stages), but also on 
      the availability of adequate supplies and protocols for efficient mosquito 
      rearing. The aim of this study was to assess the factors impacting the life 
      history of Anopheles coluzzii mosquitoes at the larval stage, in the context of 
      genetic and sterile insect approaches to control malaria vectors. METHODS: The 
      effect of different larval diets and larval rearing densities on the development 
      of An. coluzzii were evaluated in the laboratory. Emergence rate (ER), 
      pre-imaginal developmental time (DT) and adult wing length (WL) were measured 
      under different food regimes. Four diets were tested among which three were 
      provided by the Insect Pest Control Laboratory (IPCL) of the FAO/IAEA Joint 
      division. RESULTS: Data showed significant differences in the quality of the 
      different diets and suggested a negative density dependence in all three life 
      history parameters measured under tested rearing conditions. ER and WL increased 
      with food availability, but decreased with increasing larval density. Conversely 
      DT was shortened with increasing food availability but increased with larval 
      density. These data demonstrates intraspecific larval competition modulated by 
      food amount and space availability. Of the four diets tested, the one made of a 
      mix of tuna meal, bovine liver powder, brewer's yeast, squid liver powder and 
      vitamin mix (diet 2) yielded the best results as it produced a good balance 
      between ER, DT and WL. Food availability for optimal development (highest 
      survival at shortest time) was in the range of 180-400 microg/larvae/day for the 
      three diets provided by the IPCL. CONCLUSION: There is an interaction between 
      diet type, diet concentration and larval density. Best results in terms of 
      optimal larvae development parameters happen when moderately high values of those 
      three variables are observed.
