Permanent loss of male fecundity following sperm depletion in Aedes aegypti (L.).
Autor(es): Hausermann W; Nijhout H F
Resumo: The insemination capacity of Aedes aegypti males is essentially determined by the time the males reach sexual maturity. Although meiosis and spermiohistogenesis may still be observed in 5 to 10-day-old males, the sperm production in the adult is insufficient to replace the sperm lost in successful copulations. The average male can provide 4-5 females with sufficient sperm for their whole lifetime and simultaneously make them refractory to further insemination. Smaller amounts of sperm ran be transmitted to 2-4 additional females. For A. aegypti the question about permanence of induced sterility should become irrelevant if the sterilization takes place in sexually mature males.
