Predation efficiency
Webreduce the foraging efficiency of predators (Savino and Stein 1982, Anderson 1984). These findings are of sig-nificance because both the presence of refuges and re-duced predator efficiency have theoretically been shown to have a stabilizing effect on predator-prey in-teractions (eg., Murdoch and Oaten 1975). WebPredation Efficiency of E. furcellata The experiment was conducted at the laboratory condition to investigate the predatory efficiency of all the stages of the predatory bug E. furcellata on three stages (eggs, grubs and pupae) of brinjal pest, H. vigintioctopunctata.
