Diversity and Pollination Efficiency of Non-Apis Bees in Horticultural Crops at TNAU, Coimbatore, India

Abstract

Non-Apis bees play a crucial role in the pollination of horticultural crops, significantly enhancing biodiversity and agricultural productivity. This study, conducted at Tamil Nadu Agricultural University (TNAU), Coimbatore, aimed to assess the diversity and pollination efficiency of non-Apis bees across various horticultural crops. Observations were recorded through visual scanning and sweep net collection methods. A total of eight species were documented, including carpenter bees (Xylocopa fenestrata, Xylocopa pubescens), dammer bees (Tetragonula iridipennis), blue-banded bees (Amegilla zonata, Amegilla spp.), sweat bees (Halictus spp.), and alkali bees (Hoplonomia ellioti). These species exhibited distinct foraging behaviors that contributed to pollination success. Findings highlight the importance of conserving native pollinators to ensure sustainable crop yields. Strategies such as habitat preservation and reduced pesticide use can support non-Apis bee populations. The study underscores the need for integrating these pollinators into agricultural practices to enhance productivity and ecological balance.
