Anti‐mosquito antibodies decrease the reproductive capacity of Aedes aegypti

Abstract
Aedes aegypti (L.) fed on rabbits immunized with mosquito antigen showed a reduction in fecundity in the first oviposition and decreased viability of the progeny. Feeding behaviour of mosquitoes was not affected and no significant mortality was observed due to the presence of anti-mosquito antibodies in the bloodmeal. Antibodies were detected in the oocytes of mosquitoes 48 h after the bloodmeal. The role of specific antibodies in influencing fecundity is discussed.
