Abstract

The effect of light, water temperature and pH on the predation efficiency of Gambusia affinis (Baird and Girard) on Culex pipiens L. (Diptera: Culicidae) mosquito larvae was studied under laboratory conditions. Significant predation rate was recorded in light than in darkness for both male and females, despite fish size. The temperature 30°C showed the most favorable degree for predation compared with 25 and 35°C. Also, the predatory efficiency of G. affinis on mosquito larvae was significant at pH 9 than on 7 and 12.  The present results should be taken in consideration in biological control of mosquito larvae.
