Screening of Chickpea for Resistance to Pod Borer Helicoverpa armigera (Hubner) at Rahuri, Maharashtra, India

摘要

Gram pod borer, Helicoverpa armigerp (Hubner) is a keypest and with its regular occurrence in the state ofMaharashtra from early vegetative to podding stagecausing 60-80% losses (Puri et al. 1998) in chickpea. It iseconomically significant. In North India, Sehgal and Ujagir (1990) reported 90% pod damage by Helicoverpa. Management strategies for gram pod borer relied heavilyon chemical insecticides. However, concerning chemicalinsecticides, the farmers' reluctance to use it, the nonavailability, high cost, development of resistance and environmental pollution (Armes et al. 1996), haveopened up avenues for the identification and adoption ofchickpea genotypes resistant/tolerant to Helicoverpa.The genotype is the best/preferred component ofintegrated pest management.
