title: Nutritional factors and antimicrobials on development of infective larvae of subperiodic Brugia malayi (Nematoda: Filarioidea) in Anopheles quadrimaculatus and Aedes aegypti (Diptera: Culicidae).
abstract: The effects of nutritional factors and antimicrobials on the development of infective larvae of subperiodic Brugia malayi in susceptible Anopheles quadrimaculatus Say and Aedes aegypti (L.) were investigated. Larvae of both species of mosquitoes were reared on brewers yeast or a 1:1 brewers yeast-liver powder mixture. After emergence, one-half of the adults from each rearing condition were maintained on a 10% sucrose solution and the other half on a 10% sucrose solution containing 0.1% p-aminobenzoic acid (PABA). Females of both species of mosquitoes that fed on B. malayi-infected jirds showed a significant increase in the ineffective rate and intensity of infectiveness when the mosquito larvae were reared on the brewers yeast-liver powder diet. The addition of 0.1% PABA to the adult diet increased numbers of infective larvae of B. malayi that developed in Ae. aegypti but not in An. quadrimaculatus. The intensity of infectiveness of B. malayi was significantly greater when An. quadrimaculatus females were provided with a second blood meal from an uninfected jird and when females of both species were maintained on different concentrations of an antimicrobial solution.
