Abstract:
Sri Lanka is rich with highly diverse medicinal plants. Among them, Calotropis gigantea is a native plant having Ayurvedic value. It is however invasive in countries like Australia and the USA. Information on flower visitors associated with the Calotropis plant and their temporal variation becomes important for experimental purposes and to conserve them in their native range, and to eradicate the plant when invasive in an introduced range. The present study investigated flower visitors associated with C. gigantea in 11 sites of three districts in the Southern Province of Sri Lanka, i.e., Matara (03), Hambantota (04) and Galle (04).
