Effect of queen ethanol extract of Apis mellifera ligustica on behavior of workers of A. Cerana cerana

Queen ethanol extract (qee) of Apis mellifera ligustica was added on the upper bar of frame in colonies of A. cerana cerana preparing for swarming every day in spring. One week later, its obvious effect was observed, such as that queen larvae were abandoned, queen cell cups were destroyed or natural queen superseding was postponed till autumn when qee treated colonies had a 2 month long mother daughter combination. Before over wintering, not only did two queens coexist and lay eggs together, but also daughter queen stopped egg laying very late. Controls, however, built queen cells and swarmed on schedule in spring, and new queen stopped her egg laying early before winter's coming. When qee was soon dropped into queen lost colonies, worker's ovary development was inhibited. And when qee was dropped into queen less colonies where laying workers have existed, the egg laying behavior was relieved and the larva removing behavior was enhanced effectively.
