Eco-friendly and Targeted through Next-generation Approaches to Insect Pest Management

Abstract

Insect pests pose significant challenges to agricultural productivity, human health, and ecosystem stability worldwide. Traditional pest management approaches, heavily reliant on broad-spectrum chemical insecticides, have led to the development of insecticide resistance, unintended effects on non-target organisms, and environmental contamination. In response to these challenges, next-generation approaches to insect pest management are emerging, focusing on eco-friendly and targeted strategies. This review article explores the latest advancements in sustainable pest management, including the use of biopesticides, semiochemicals, biotechnology-based approaches, and integrated pest management (IPM) strategies. Biopesticides, derived from natural sources such as plants, microorganisms, and insects, offer effective and environmentally benign alternatives to synthetic insecticides. Semiochemicals, including pheromones and allelochemicals, can be exploited for pest monitoring, mating disruption, and attract-and-kill strategies. Biotechnology-based approaches, such as RNA interference (RNAi), CRISPR/Cas9 gene editing, and transgenic crops, provide novel tools for targeting specific pest species and reducing reliance on chemical insecticides. IPM strategies, which combine multiple pest management tactics based on ecological principles, offer a holistic and sustainable approach to pest control. The adoption of these next-generation approaches faces challenges, including regulatory hurdles, public acceptance, and the need for further research and development. However, by embracing eco-friendly and targeted pest management strategies, we can reduce the environmental impact of insect pest control, promote biodiversity conservation, and ensure sustainable food production for a growing global population. Future research should focus on optimizing and integrating these approaches, understanding their long-term ecological impacts, and developing effective knowledge transfer mechanisms to promote their widespread adoption.
