Biocontrol efficacy of Gerris (A) spinolae, Laccotrephes griseus and Gambusia affinis on larval mosquitoes.
Predation experiments using Gerris (A) spinolae, Laccotrephes griseus and Gambusia affinis were conducted against IV stage culicine larvae with varying prey densities. Ranking of individual predatory efficiency showed the sequence: large Gambusia > medium Gambusia > small Gambusia > female Laccotrephes > male Laccotrephes > Gerris. Predation under coexistence reveals the significance of predatory efficiency of different predator combinations with reference to prey density and exposure period.
