The functional response of the predators mirid bug, C. lividipennis and wolf Spider, P. pseudoannulata were examined by a series of experiments at different densities of eggs and nymphal instars of the prey. To determine the influence of density and stage of prey on consumption, the eggs and nymphal instars were offered to the predators. The experiments were carried out at the constant temperature of 30oC and 70% R.H. in an incubator. Each density of the prey (eggs and nymphal instars) was replicated three times. The results were recorded at 24 hours intervals.
