Abundance and diversity of pollinator in and around Sri Sai University Campus, Palampur, India
Abstract : The distribution of insect pollinators in Brassica rapa, Rosa rubiginosa, and Ageratina adenophora was conducted from February to May 2025 Sri Sai University campus, Palampur (India). The observations were made during day time to note down the activity of insect pollinators. Five insect species were recorded, belonging to four families under three major orders: Hymenoptera, Diptera, and Lepidoptera. The peak activity of these insect pollinators was predominantly observed during morning hours. Among the recorded species, the order Diptera exhibited the highest abundance, with the Syrphis species, a type of hoverfly, being the most prominent pollinator. Other notable species recorded included Pieris brassicae (cabbage butterfly) from the order Lepidoptera and three insect species from the order Hymenoptera, namely Apis dorsata (honey bee), Polistis species (yellow wasp), and Vasalis species (giant wasp). Among these, hoverflies were found to be the most abundant, followed by cabbage butterflies, honey bees, yellow wasps, and giant wasps in decreasing order of their abundance. The study also highlighted that Brassica rapa attracted more insect pollinators compared to Rosa rubiginosa and Ageratina adenophora, indicating a preference of the pollinators for this plant species. This research provides valuable insights into the diversity and relative abundance of insect pollinators and their foraging patterns, which is crucial for understanding pollinator dynamics and promoting sustainable agricultural practices.
