Abstract: The presence of the predators can alter the prey niche in the community. We evaluated the influence of the predator, Anisops sardea on mosquito Culex pipiens molestus population by predation, and non-consumptive effect by life-cycle prolongation in predator presence and residual kairomones. The predation depends on prey density, individual A. sardea predated 16.0-19.7 and 24.7-29.3 3rd larvae/ day at the densities 50 and 100 larvae / liter respectively, with clearance rate 0.19 and 1.1 for those densities. The predatory impact along four days within 8 hours daytime ranged between 0.98-1.20. The non-contact presence of the predator folded the larval stadium from 11.9 in contract to 23.7 days while it increased to 16.0 days at residual kiromone, the pupal stadium in control 5.8 days, then increased to 7.8 days in the two treatments. Thus, release of notonectid A. sardea will effectively control C. pipiens molestus by predation and besides decrease number of generations through immature stages extension. A. Sardea can be actively used as essential factor in integrated vector control.
