Integrated Pest Management for the Gram pod borer in Chickpea

Chickpea (Cicer arietinum L.) is a major pulse crop of semi-arid and subtropical regions, valued for its role in nutritional security, soil fertility improvement, and farm income. However, its productivity is severely constrained by the gram pod borer, Helicoverpa armigera (H?bner), a highly polyphagous and destructive insect pest with a wide host range and global distribution. The pest remains active throughout the year and causes serious damage to chickpea during the rabi season (November?March) by feeding on leaves, flowers, and developing pods, resulting in yield losses of 20?50% under moderate to severe infestations. Owing to its high reproductive potential, migratory behavior, and ability to develop resistance, sole dependence on chemical insecticides has become ineffective and environmentally unsustainable. Integrated Pest Management (IPM) offers a holistic and ecofriendly approach by combining cultural, mechanical, biological, host plant resistance, and need-based chemical control strategies. Important IPM components include summer deep ploughing, timely sowing, crop rotation, intercropping, installation of bird perches, use of light and pheromone traps, conservation and augmentation of natural enemies, application of biopesticides such as HaNPV, Bacillus thuringiensis, botanicals, and selective insecticides. Adoption of resistant and tolerant chickpea varieties further enhances pest suppression. The integration of these management practices helps in reducing pest population below economic threshold levels, minimizing pesticide load, conserving beneficial organisms, and ensuring sustainable chickpea production.
