ABSTRACT
The main aquatic insects bioregulators of mosquito larvae living in different reservoirs at the "Pantanos de Villa", Lima, Perú, were collected and determined. Mosquito larvae and pupae of the Culex quinquefasciatus Say and Aedes scapularis Rondani species were found in water reservoirs where aquatic insects are not observed. In those where there were these effective bioregulators of mosquito larvae such as Ischnura ramburii (Selys), Ceratura capreola (Hagen), Erithrodoplax cleopatra Ris, Aeschna elsia Calvert, Tropisternus dorsalis Brullé, Thermonectes circunscripta Latr, Belostoma asiaticum (Mayr), and Buenoa absidata Truxal, no mosquito larvae were found. The species of the aquatic insects collected in the reservoirs as well as the physical and chemical variables of the water are shown.
