Foraging behaviour of Apis cerana on sweet orange (Citrus sinensis var. Red Junar) and its impact on fruit production

摘要

The sweet oranges (Cirus sinensis var. Red Junar) have been widely planted under the middle hill region of Nepal. They bloom during March-April and produce plenty of nectar and pollen. Flowers are usually self-compatible but benefit to a great deal from cross-pollination by honeybees. Honeybees collect lots of honey from citrus flowers.
