The aim of this project was to determine if supplementing human blood with methionine would affect life history traits of Aedes aegypti mosquitoes. We fed mosquitoes either human blood, or human blood supplemented with low or high methionine. We tracked the survival, number of eggs laid and the proportion of larvae that hatched following the blood-feeding treatments. The data demonstrated that supplementing with methionine had little effects on survival or fecundity of mosquitoes.
