Abstract
Pollination by insects is critical for seed production in onion (Allium cepa L.), a cross-pollinated crop that relies heavily on biotic pollinators. This study was conducted during the 2023–24 cropping season in the Rangpur region of Bangladesh to evaluate the diversity of foraging insects in onion fields and their impact on seed yield and quality. A randomized full block design was used to examine six different pollination techniques, including dill intercropping, open pollination, honeybee-assisted pollination, insect exclusion and hand pollination. A diverse array of pollinators was recorded, with honeybees (Apis mellifera, Apis cerana), solitary bees (Megachile spp.), hoverflies (Eristalis spp.), and butterflies (Danaus spp.) being the most frequent visitors. Pollinator activity peaked between 9:00 AM and 12:00 PM, with solitary bees and honeybees exhibiting the highest visitation rates. Seed yield was significantly enhanced in treatments with honeybee colonies (823.3 kg/ha), open pollination with dill (781.6 kg/ha) and hand-assisted pollination (753.0 kg/ha), compared to the lowest yield in insect-excluded plots (355.0 kg/ha). Seed quality parameters-including 1000-seed weight, germination rate, and reduced deformity-also improved significantly in insect-accessible treatments. These findings highlight the indispensable role of foraging insects in onion seed production and underscore the need for pollinator-friendly practices, such as managed bee colonies and flowering intercrops, to optimize yield and seed quality.
Key Words: Foraging insects, Diversity, Onion seed yield and Rangpur.
