Impacts of Pesticide Residues on Pollinator Diversity and Ecosystem Services

Pollinators play a crucial role in maintaining biodiversity, supporting ecosystem stability, and enhancing agricultural productivity. An increasing use of pesticides in modern agriculture has raised serious concerns regarding their negative impacts on pollinator populations. Pesticide residues present in crops, soil, water, and surrounding vegetation can expose pollinators to toxic substances that affect their survival, reproduction, and behavior. Declines in pollinator diversity have been reported in many regions worldwide, threatening essential ecosystem services such as crop pollination and natural plant reproduction. This review examines the sources and persistence of pesticide residues, their effects on different pollinator groups, and the broader consequences for ecosystem services and food security. It also highlights sustainable agricultural practices and integrated pest management approaches that can help reduce pesticide-related risks while maintaining effective crop protection. Protecting pollinators is essential for sustaining agricultural productivity, conserving biodiversity, and ensuring long-term ecological balance.
