摘要

Chickpea cultivation faces a significant threat from Helicoverpa armigera, leading to substantial yield losses globally. Traditional pesticide applications are problematic due to environmental and health concerns. Recent approaches focus on sustainable pest management by boosting plant immunity. This review explores various strategies to enhance chickpea resilience against H. armigera, including morphological barriers, induced physiological responses, defense-related enzymes, and molecular signaling pathways such as jasmonic acid-mediated responses. The role of plant secondary metabolites- phenolics, flavonoids, protease inhibitors, and alkaloids—in conferring antibiosis and antixenosis is discussed. Emerging interventions such as biopesticides, biological control agents, marker-assisted breeding, RNA interference (RNAi), and CRISPR/Cas-based genome editing are highlighted as promising tools for durable resistance. Integrated pest management is crucial for sustainable chickpea cultivation. Overall, adopting holistic approaches is vital for fortifying chickpea immunity, minimizing chemical dependency and ensuring global food security.
