Studies On Comparative Biology Of Chinese Bee And Italian Bee

Chinese bee is native honeybee variety, because of introduction of Italian bee into our country; its quantity and distribution range extreme to dwindle, contract to the mountain and forest region. For offering theoretical foundation in giving protection work of Chinese bee, this thesis has been studied on the competition in gathering, robbing and nuptial flight mating between Chinese bee and Italian bee. Studies have shown as follows:I.Chinese bee have two fly peak, critical flight intensity 3604 per hour; Italian bee have three fly peak, critical flight intensity 7669 per hour, intensity greater than Chinese bee and Italian bee collection range cover and greater than Chinese bee obviously totally. When existing in same region (in the honeybee flying radius), because of the competition to the food, in the course of gathering Italian bee adopt behavior of driving Chinese bee. There are a negative corresponding relationship between the output of honey(y) and flight intensity(x),theequation being found as y = 10-8x2 - 0.1299,y= 6×10-9x2 - 0.3529 separately.2. The competition fight peak of food resource between Chinese bee and Italian bee mainly takes place in latter stage of blooming, namely under the nectar and pollen source lacks external world. In apiary, Chinese bee and Italian bees to be raised in same region, robbing phenomenon take place. For individual Chinese bee is small, colony is weak, Chinese bee is in inferior position in struggle with Italian bee. After being robbed, Chinese bee groups tendency weak, escape, even the whole group is destroyed when being serious.3. In mating season, Chinese bee drone and Italian bee drone have the same mating tour time. Space distribution of drone is unequal; drone congregation area exists and drone congregation area of Chinese bee and Italy bee overlap.4. In early spring if mature period of drone is close to, and Chinese bee's raise district is same as Italian bee, often causing mating success rate of Chinese bee relatively lower.5. In sunny warm with gentle breeze afternoon, Chinese virgin queen, Italian virgin queen and the bait maked of her draw liquid have function of luring to the Italian bee drone; And Italian bee drone chase and attempt to mate with Chinese virgin queen, the behavior caused mating interferes to Chinese drone and Chinese virgin queen.
