Agricultural systems are a complex balance of biological, agronomic and economic factors with agricultural producers closely managing crop-pest interactions. Climate change will fundamentally alter the underlying agro-ecosystems through elevated temperatures and CO2 levels, leading to changes in pest activity and population levels. Higher temperatures will increase rates of development and the number of pests surviving the winter temperatures. Geographic distributions of crops, pests, and predators are expected to shift, with pests extending to higher latitudes. Climate-induced changes in pest activity are likely to affect agricultural production in several ways. Increased pest populations will stress crop plants and increase the risk of crop loss, reducing yield and/or quality of harvest. Worldwide food plants are damaged by more than 10,000 species of insects. The yield loss by insects reaches as high as 60-70%. In India agriculture is currently suffering an annual loss of about Rs. 8, 63, 884 million due to insect pests. Therefore the present study makes a modest attempt to explore the existing occurrence of insect pests and diversity of their associated insects in agriculture field at Managaseri Village, Virudhunagar district. During the study period Odonata, Orthoptera, Lepidoptera, Coleoptera, Diptera and Homoptera insects were identified and the results are discussed.
