Definition

noun

A method of controlling the mosquito population, especially those that are carriers of disease, by chemical, biological, or other means


Supplement

Mosquitoes are insects of the family Culicidae. The females of several mosquito species are ectoparasites, feeding on blood of their host (e.g. humans, birds, amphibians, reptiles, etc.). Some of them are vectors of disease. Some of the diseases they transmit are malaria, dengue fever, yellow fever, Zika virus, filariasis, Chikungunya, etc. Because many of these diseases they transmit are deadly, they are controlled in different ways. One of the ways to control their population is by source reduction wherein their breeding places are eliminated.

Another way is by introducing biological controls. Biological control is a method of controlling a group of organisms (e.g. pests) with another set of organisms (e.g. natural predators of the former). It makes use of parasitism, predation, or herbivory. Biological control agents of mosquitoes include fish (e.g. mosquitofish, tilapia, carps, killifish, and minnows), copepods, dragonfly (nymphs and adults), geckoes and lizards, and the soil bacterium, Bacillus thuringiensis, especially the Bt israelensis. Many of these biological control agents target mosquito larvae. Another biological control agent is fungi, e.g. Metarhizium anisopliae and Beauveria bassiana.
