Abstract:

To explore the role and economic value of honeybee pollination in oilseed rape production, the annual value of the rape production attributable to honeybee pollination and the pollination requirements of bee colonies were evaluated based on honeybee pollination dependency model. The results indicated that the total value of honeybee pollination service to oilseed rape production in China in 2018 was 10.419 billion Yuan, accounting for 15.75% of the annual domestic oilseed rape production value (almost 66.141 billion Yuan). In Sichuan, Hubei and Hunan, the value of honeybee pollination service to rape production was all over 1 billion Yuan. It is estimated that over 16.3765 million bee colonies are needed each year to pollinate oilseed rape in China, more than the present 9.0884 million bee colonies. Hunan and Sichuan have the largest demand for honeybee pollination in rape production, accounting for more than 1/3 of the total domestic bee colonies. Therefore, bee pollination is an important input in rape production, the public awareness of the economic value of bee pollination should be gradually raised, and bee pollination technology in rape production should be vigorously promoted.

Key words: honeybee pollination, oilseed rape, value of pollination service, pollination demand, evaluation
