Temperature, larval diet, and density effects on development rate and survival of Aedes aegypti (Diptera: Culicidae).

Many environmental factors, biotic and abiotic interact to influence organismal development. Given the importance of Aedes aegypti as a vector of human pathogens including dengue and yellow fever, understanding the impact of environmental factors such as temperature, resource availability, and intra...
