Biological Control of Mosquitoes

Biological control of mosquitoes involves the use of naturally occurring organisms that are pathogenic to mosquitoes. These organisms can be introduced as predators, or they can be used to disrupt the life cycle of mosquitoes.

A number of naturally occurring bacteria are toxic to mosquito larvae. These bacteria interfere with the digestive systems of mosquito larvae, thereby killing them within days. These bacteria can be introduced directly into mosquito breeding habitats. Other biocontrol agents include predatory fish. Fish species are stocked into mosquito breeding habitats to feed on mosquito larvae. Some species of lizards also consume adult mosquitoes.

There are also several species of nematodes and fungi that have been used as biological control agents. Some of these nematodes and fungi are predators of mosquito larvae, while others are parasites. Insect control products that contain these biological control agents are approved by the Environmental Protection Agency (EPA).

Biological control of mosquitoes can also involve the use of contact poisons. These contact poisons are designed to kill mosquito larvae. They can be placed in potted plants and other containers. These poisons can also be used to prevent mosquito breeding in stagnant water.

Adulticides are only used when nuisance threshold values are reached. These adulticides are released in airplanes or helicopters and drift through the area above the mosquitoes. They are intended to stay airborne as long as possible.

When choosing an adulticide, it is important to choose one that is effective and will not harm the native species of mosquitoes. The effectiveness of adulticides will depend on the type of mosquitoes present and the weather conditions. It is important to consult with a professional before choosing an adulticide.
