Populations of the tree-hole mosquitoes Aedes geniculatus and A. triseriatus were cultured at different food levels larval densities to determine fitness consequences variation in these factors for each species. A composite index four correlates calculated population. Response-surface regression analysis indices indicated that two species have fundamentally responses density: The interaction quadratic effects had a strong influence on but little impact geniculatus. In both species, was most sensitive male female pupal weight, less sex ratio development time, least pupation success. response-surface model explained over 90% triseriatus, only two-thirds We suggest is more homeostatic polymorphic traits, predict life-history characters will higher heritabilities than triseriatus.
