%X the content of the digestive tract of 4 authoctonous species of fishes that presented characteristics of larvivorous fishes was analyzed. it was found that 28 % of the caught specimens of aequidens pulcher presented in their gastrointestinal content residues of larvae and pupae of mosquitoes combined with other food, and that 26 5 has only larvae and pupae. in aequidens coeruleopunctatus, 63 % of their content was larvae and pupae with other food, whereas 10 % had only larvae and pupae. 56 % of the poecilia caucana specimens had larvae and pupae with other food, and 34 % only larvae and pupae. poecilia reticulata contained larvae and pupae with other food in 62 % and 33 % only had larvae and pupae. these results show an effective bioregulator activity in these fishes identified as larvivorous under natural conditions.
