Abstract

Honey bees are important pollinator of agricultural and horticultural crops. Moringa, MoringaoleiferaLam. commonly known as drumstick is a vegetable native to India. Due to medicinal and nutritional properties it is also called as‘miracle tree’.It is highly cross pollinated and entomophilous, bees were major pollinators. Flowers can be a source of nectar and pollen for the pollinators. The objective was to describe the pollinator community in moringafields, to determine the trap colour that is most appropriate for characterizing their abundance and diversity. Bowl trap is a common method of sampling bees.Totally, bowl traps of three different coloursviz., fluorescent yellow, blue and white were used to capture the insect pollinators. Bowl trap catches were recorded for 10 days during peak flowering at 08.00 to 18.00 h. When all trap type captures were combined, we collected 601 individuals and at least 21 species. From the 21 insect species collected, fourteen were belonged to Hymenoptera and seven belongstoDiptera.The most abundant species collected was Condylostylus sp. (Diptera: Dolichopodidae) followed by Halictus sp. (Hymenoptera: Halictidae) and Sarcophaga sp. (Diptera: Sarcophagidae). Most pollinators were captured in fluorescent yellow bowls (353 individuals, 21 species), blue bowls (137 individuals, 18 species) and white bowls (111 individuals, 16 species). In fluorescent yellow trap, Apisceranaindica was collected more followed by Polistes sp., Amegillazonata and Xylocopasp. Our data suggest a diverse community of pollinators composed of mostly native flies and solitary bees visit moringa fields and forage on their flowers.
