Seth CO-PI & Professor of Zoology University of Delhi, Delhi-110 007 Investigations on the Present Pigeonpea Pest Complex and Their Management, with Emphasis on Radiation Technology as An Integral Component in IPM

3. Objectives 1. Studies on changed pest scenario and their Natural Enemies in traditional and non traditional pigeonpea growing areas 2. Ecological studies on emerging pests of pigeon pea 3. To study the use of nuclear (radiation) technology against M. vitrata and Callosobruchus spp 4. To study the Mapping of resistance to conventional and new chemistry against pigeon pea insect pests. 5. Studies on pigeon pea sterility mosaic disease and its management
