UNIVERSITY OF AGRICULTURAL SCIENCES, RAICHUR AND UNIVERSITY OF DELHI B.V. Patil Principal Investigator & DOE UAS,Raichur , Karnataka & R. K. Seth CO-PI & Professor of Zoology University of Delhi, Delhi Investigations on the Present Pigeonpea Pest Complex and Their Management, with Emphasis on Radiation Technology as An Integral Component in IPM

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

Objective.3 To study the use of nuclear (radiation) technology 1. Radio-biological investigations related to F 1 sterility ( modified Sterile insect technique) in management of spotted pod borer, Maruca vitrata, 2. Efficacy of gamma irradiation, as post harvest phyto-sanitary treatment, against bruchids, Callosobrachus analis, C. maculatus, C. chinensis
