Insect pollination: An incredible natural service for food sustainability in agroecosystems-A review

Insect pollination plays a pivotal role in the reproductive success of many flowering plants, essential for maintaining biodiversity and ensuring food security in agroecosystems. While plants rely on various pollinators, insects are the primary contributors to this natural service, transferring pollen as they forage for nectar and pollen rewards. This mutualistic interaction between plants and pollinators is crucial for the sustainability of both natural and agricultural ecosystems. However, the increasing threat to pollinators from habitat loss, pesticide use, and climate change jeopardizes this vital ecosystem service. The decline in pollinator populations is particularly concerning for global food security, as many crops depend on insect-mediated pollination. This review examines the mechanisms of insect pollination, the factors contributing to pollinator decline, and strategies to enhance pollinator populations. Emphasis is placed on the importance of conserving native pollinators, optimizing agricultural practices, and mitigating environmental stressors to sustain pollination services for future generations.
