Male sexual history influences female fertility and re-mating incidence in the mosquito vector Aedes aegypti (Diptera: Culicidae).

摘要: Abstract Aedes aegypti is the primary vector of several arboviruses that impact human health including dengue, Zika, and yellow fever viruses. The potential Ae. females to transmit viruses enhanced by mating-induced behavioral physiological changes increase female host-seeking behaviors, blood-feeding frequency longevity. are due receipt male seminal fluid proteins (SFPs) during copulation. SFPs also inhibit re-mating—re-mating incidence significantly reduced in initial hours after mating nearly absent 24 h. Males, however, not limited number they can inseminate able mate with multiple succession. As successive depletes SFPs, we examined parameters fertility re-mating recently mated males. Males two strains (Colombian Thai) were five consecutive times fecundity, resulting larvae hatch percentage each sequence was assessed. In both strains, found males three succession without impacting their mates. However, significant declines larvae, observed a third mating. Male size influenced fecundity as mates small showed further reductions compared big consecutively. Seven days assays, rate fifth increased strain: 33%; Thai 48%) first (0% strains). Re-mating small, strain where 82% re-mated 0% females. Finally, show regardless size, experimental similarly fertile control when for sixth time 48 h showing recover 2 d.
