Mesocyclops is a genus of copepod crustaceans in the family Cyclopidae. Because the various species of Mesocyclops are known to prey on mosquito larvae, it is used as a nontoxic and inexpensive form of biological mosquito control.

Biological control[edit]

Individuals of Mesocyclops can be easily harvested, bred and released into freshwater containers where the Aedes aegypti mosquito larvae (the vector of Dengue fever) live.[2] A big advantage of the Mesocyclops is that it is possible to teach schoolchildren how to recognize and collect them so that communities are able to perform sustainable mosquito control without much professional or governmental assistance.

A field trial in Vietnam has shown that large-scale elimination of Aedes aegypti larvae is possible. Because Mesocyclops is a host for the parasitic round worm Guinea worm (Dracunculus medinensis, the causative agent of dracunculiasis), this method is potentially hazardous in the small number of countries where the Guinea worm still occurs. Furthermore, many cultures have traditions and customs that forbid the introduction of animals into freshwater storage vessels as dangerous taboos.[3][4][5]


The genus Mesocyclops contains 129 species:[6]
