Abstract

Comparative predatory efficiency of Rhynocoris marginatus (Fabricius) was assessed on two cotton pests namely, Helicoverpa armigera (Hubner) and Spodoptera litura (Fabricius). Gradual increase in prey consumption was recorded by the progression of the developmental stages of the predator. Adult females consumed more than males and consumption decreased with the later prey instars. Among the two prey species, S. litura was more preferred.
