Abstract

Spiders play an important role as generalist predators of many insect groups in agricultural ecosystems. In the present study five different spider species like Argiope pulchella, Hippasa agelenoides, Plexippus peteresi, Oxiopus biraminicus and Paradosa pseudoannulata are collected from agriculture ecosystems in the study area of Western Ghats  along with common pests like Deudorix Isocrates (Anar butterfly), Ferrisia virgata (Mealy bug) and Virachola Isocrates (Friut borer) in the same fields. Spiders were maintained in plastic tubs and fed by the insect pests, the killed pests and consumed by spider was counted at the end of 24 hours. The predatory activity of A. pulcella was very high (3.98±0.23), followed by H. agelenoides (3.49±0.46), O. biraminicus (2.07±0.38), P. peteresi (2.06±0.34) and very low in P. Pseudoannulata (1.73±0.23). More number of pests were controlled during the multople species (54%) than single pest species (47%) and web builders (58%) controlled more pests than the hunters (42%).
