Role of Native Pollinators Versus Introduced Honeybee Species in Enhancing Crop Yield

Abstract This study investigates the comparative role of native pollinators and introduced honeybee species (Apis mellifera) in enhancing crop yield across diversified farming systems. Conducted in mixed-crop agricultural regions, the research utilized a field-based comparative approach, observing pollinator visitation, pollen deposition, and resulting crop yields across farms dominated by native pollinators, Apis mellifera, and a combination of both. Key parameters such as fruit set percentage, seed count, and yield per plant were measured for tomato crops. Results indicated that native pollinators, including carpenter bees, stingless bees, and bumblebees, exhibited significantly higher per-visit pollen deposition and were more active under variable weather conditions compared to Apis mellifera. Mixed-pollinator farms achieved the highest yield metrics, suggesting that pollinator diversity enhances pollination efficiency and yield stability. Additionally, native-only farms demonstrated better resilience in cloudy weather, with lower declines in pollinator activity and crop output. These findings highlight the ecological and agronomic benefits of integrating native pollinator conservation into agricultural practices. Overreliance on managed honeybees alone may reduce ecosystem resilience and long-term productivity. Promoting a diverse pollinator community offers a more sustainable path toward food security and ecological stability.
Keywords Native pollinators, Apis mellifera, crop yield, pollination efficiency, pollen deposition, biodiversity, sustainable agriculture, weather resilience, tomato pollination, ecosystem services.
