Abstract


Many literature citations state that Coleóptera of the family Dytiscidae are predators of larvae of Culicidae. In an area of primative forest, small receptacles of water were introduced in order to study ecology of Dytiscidae. A new species of the genus Copelatus was discovered and found to be a predator of mosquito larvae. Field observations of behavior colonization of receptacles and aspects of the controle of mosquito population were made. In the laboratory were studied resistance to dessication, dispersion, aquatic respiration, relationship with other predators and its influence upon development of Culicidae larvae. Copelatus appears to be an efficient agent of biological control of larva of Culicidae in small reservatories of water.
