A study on larvivoricity of platy (Xiphophorus maculatus) was carried out for 24 h.  The experiment was carried out in aquarium tanks consisting of individual male platy (T1), individual female platy (T2), 2 male platy (T3), male and female platy (T4) and 2 female platy (T5). Each tank containing 24 h pre-starved fish were offered 600 numbers of mosquito larvae and the consumption rate/tank was recorded at 24 h. On an average, the tank holding 2 female fish (T5) consumed 579.3 number of mosquito larvae registering the highest consumption rate followed by T4 containing male and female fish consumed 427.3 no. of mosquito larvae, T2 containing individual female fish consumed 271.7 no. of mosquito larvae, T3 containing 2 male fish consumed 251 no. of mosquito larvae and T1 containing individual male fish with 124.7 no. of mosquito larvae. The mosquito larvae consumption rate was T5>T4>T2>T3>T1. The water quality parameters recorded during the study were well within the tolerable range for platy fish. The statistical analysis performed by One way ANOVA showed no significant difference between the group T2 and T3, but there was a significant difference among the groups T1, T4 and T5. The present study indicated that the platy may be used as potential larvivorous fish to control mosquito larvae. Further, the larvivoricity rate of female platy is higher than male.

Key words: Mosquito larvae, Platy, Larvivorous, Xiphophorus maculatus.
