Abstract

The functional responses of three species of predatory phytoseiid mites, Neoseiulus calorai, (Corpuz and Rimando), Neoseiulus longispinosus (Evans) and Proprioseiopsis lenis (Corpuz and Rimando), to eggs, larvae, protonymphs, deutonymphs and adult females of Tetranychus urticae Koch, were determined. The predation tests were conducted on rose leaf discs inside Munger cells over a 24h period at 27±1°C. Prey densities ranged from 1 to 60 per leaf disc for each prey stage. All three species were effective predators of eggs T. urticae but N. calorai and P. lenis were effective also on larvae. Based on R2 values, both type I and Type II curves provide good fit on the functional response data.
