Spatial Insect Biodiversity and Community Analysis in Selected Rice Fields of North Bihar

Abstract

The rice is a major food crop of India. The rice cultivation has maintained its priority status in the agriculture sector of the country. The intensive management practices adopted by the practitioners have been resulted in genetic erosion, thus affecting the species composition of the rice field ecosystems. There are obvious differences in species composition and community structure of insects in upland and lowland fields affecting also crop production per year. This paper presents a work carried out on the biological diversity of rice field ecosystems of India and proposes the need for conservation strategies to ensure the sustainability of these rice field
ecosystems in the long run in future.
