Biotech tools vital for pest control: Experts

The National Academy of Agricultural Sciences (NAAS), Ludhiana chapter, in association with the Indian Society for the Advancement of Insect Science (INSAIS), Ludhiana, organised a special lecture on “Applications of Modern Tools of Biotechnology for Pest Management and Food Security.” Dr HC Sharma, former Vice-Chancellor of YS Parmar University of Horticulture and Forestry, Solan, was the guest speaker.

In his lecture, Dr Sharma emphasised the transformative potential of biotechnology in boosting food production through effective pest management. He noted significant advances in genetic engineering, particularly the incorporation of Bacillus thuringiensis (Bt) toxin genes into crops such as cotton, maize and potato, which are now widely cultivated for insect resistance. Dr Sharma stressed the importance of developing biotech solutions that are affordable, environmentally safe and effective across diverse agro-ecosystems.

He advocated integrating exotic genes with traditional host plant resistance and enhancing natural enemies of pests through genetic engineering. He also called for strict biosafety regulations and wider farmer access to biotechnological innovations to ensure sustainable and equitable pest management strategies that protect both crops and ecosystems.

The lecture was followed by a vibrant discussion between faculty and students, focusing on the application of biotechnological tools, regulatory challenges and future prospects for sustainable, effective pest management across diverse agro-ecosystems.

Dr Ajmer Singh Dhatt, convener of the NAAS Ludhiana Chapter and director of research, PAU, emphasised the transformative impact of recombinant DNA technology on crop improvement, particularly in enhancing resistance to pests, diseases and drought. He underscored the importance of developing biotechnological solutions that are commercially viable, environmentally sustainable and adaptable across diverse ecosystems, while ensuring safety for non-target organisms.

Highlighting the critical role of modern biotechnological tools in advancing pest management and ensuring food security, Dr Dhatt advocated for the adoption of innovative approaches such as genetic engineering, RNA interference and molecular diagnostics, which offer precise, effective and eco-friendly alternatives to conventional agricultural practices.
