Why
Mating induces physiological changes in mosquitoes, including gut growth and immune suppression, which are linked to reproductive physiology and potentially affect arbovirus vector competence.
The Frontline Impact
How this affects you
The findings demonstrate that mating-dependent physiological trade-offs persist in natural mosquito populations. This reproductive physiology may be an underappreciated factor influencing the transmission of arboviruses like Zika.
