Functional response and density dependent feeding interaction of Apertochrysa astur against different densities of eggs, nymph, pupa and adults of Paralerodes bondari peracchi BNW were evaluated at HRS, Ambajipeta. All the instars exhibited highest consumption percentages at lower prey densities across all bondars nesting whitefly (BNW) stages, while no response was observed to adult of BNW. Among the three instars, third instar was found to be effective in feeding on all the developmental stages. In the entire study period the linear coefficient of functional response equation for all the predator stages of BNW was negative and significantly different from 0 (p < 0.01), indicated a type II functional response. Overall, functional response of A. astur to different densities of eggs, nymph and pupae, and adults of BNW followed type II functional response with third instar of A. astur being the most effective predatory stage.
