Mosquito Ecology and Disease Control

Mosquito ecology is an essential aspect of understanding the transmission of mosquito-borne diseases.

The female mosquito requires a blood meal for oviposition, but some species, like Culex molestus, can lay eggs without taking blood meal in certain situations. The gonotrophic cycle is crucial for mosquito propagation and disease transmission, and temperature and the availability of hosts can affect the cycle. Different mosquito species have varied feeding preferences, including host preference, feeding time, feeding area preference, and resting behavior, which are crucial factors for disease transmission and vector control.

Mosquitoes’ overwintering behavior varies among species and can be triggered by the length of daylight and low temperature. Aedes mosquitoes use egg stages to overwinter, Culex mosquitoes use adult stages, which can turn into hibernation status, and other species can use larvae stages to overwinter.
