Eco-friendly technology nowadays is an important event to maintain the pollutant free and safe environment. Such condition to certain extent may be provided by the predatory insects namely the reduviids .They act as bio-control agents on insect pests and play an effective role in eco-friendly technology. To prove reduviids as effective bio control agent on insect pest, the functional response experiment was carried out in the pest of Solanum melongena Linn (brinjal) the Pterophorus lienigianus (Z) in a brinjal agro ecosystem, using the reduviid predators Rhynocoris fuscipes (Fabricius) and Endocus inornatus (Stal).The number of prey was kept constant through out the experimental period.“Disc”equation of Holling (1959) Y = a(Tt - by) x was used to describe the functional response of both predators. Study on the functional response in R. fuscipes and E. inornatus suggested that both were capable of suppressing the pest population by killing more number of pests. Hence they could be mass cultured and effectively employed as bio control agent for suppressing the pest population of brinjal. Managing the pest by using natural predators will minimize the usage of pesticides, and make the environment free from toxic pollutant.
