PREY PREFERENCES OF COMMONLY ENCOUNTERED SPIDERS IN THE RICE AGRO-ECOSYSTEM

Abstract

The predatory potential and prey preferences of Lycosa pseudoannulata, Tetragnatha javana, Eucta javana, Thomisus cherapunjens, and Oxyopes javanus were studied. Among the spider species tested. L. pseudoannulata was the most efficient predator and it had the highest predatory potential with BPH or WBPH. L. pseudoannulata preferred planthoppers to Nephotettix virescens whereas T. cherapunjeus and O. javanus preferred N. virescens to planthoppers.

Keywords: Spiders, prey preferences, predatory potential, leaf-hopper, planthopper
