Why

Mating induces gut growth and suppresses immune responses in Aedes aegypti, a physiological trade-off that persists in natural populations and may influence arbovirus infection probability.

The Frontline Impact

How this affects you

Reproductive physiology in Aedes aegypti mosquitoes is identified as an underappreciated determinant of vector competence, potentially influencing the transmission of arboviruses like Zika virus.
