How Do Mosquitoes Die in Cold Weather?
WouterDespite their appearance, mosquitoes are not all doomed to die in cold weather. They can survive for months if they are left alone, and some species have developed an adaptation to colder climates. However, the best way to prevent them from biting you is to take measures that will keep the female mosquitoes from laying their eggs.
There are two main types of mosquitoes: male and female. The male adult mosquito emerges first. He feeds on plant nectar. His short life span makes him less likely to bite. He lingers near a breeding site, waiting to mate. In order to live, the female adult mosquito must lay a large number of eggs.
The thoracic aorta is the primary organ driving the circulation of hemolymph in mosquitoes. It is encased in a COPI (coatomer protein 1) envelope. The COPI system is designed to break down the proteins in the blood, then release the digestive enzymes into the gut.
In colder weather, the female mosquito begins to slow down. The brain of the mosquito aids in vision and tasting. It also helps mosquitoes move around and detect scents. It also contains a feeding mechanism that keeps the body from freezing.
The most dangerous mosquito species, Anopheles, is believed to breed saliva, which kills millions of people each year. The saliva contains the pathogenic parasite that causes malaria. It takes about 10-12 days for the parasite to complete its life cycle.
Several mosquito species will hibernate during the winter months. This is similar to the way that mammals hibernate. They rely on the glycerol in their bodies to help them survive in sub-zero temperatures.
