中蜂雄蜂封盖气孔结构及功能分析

Studies on the Structure and Function of the Pore in the Drone Cell Capping of Apis cerana cerana

以中华蜜蜂和意大利蜜蜂为实验材料,利用扫描电镜观察中蜂雄蜂封盖气孔形成过程和不同封盖结构,利用全自动数字式物透气量仪测定不同封盖透气性。结果表明：中蜂雄蜂封盖第7天,已形成气孔结构,直径0.4-0.5 mm;中蜂雄蜂封盖透气性显著低于中蜂工蜂、意蜂工蜂和雄蜂、封盖,并且中蜂雄蜂封盖质地结构紧密。人工封盖中蜂雄蜂气孔实验表明：中蜂雄蜂封盖气孔对雄蜂发育有一定影响。

Apis mellifera and Apis cerana cerana were used in this study. A scanning electron microscopy（ sem） was employed to observe the forming process of pores on the cell caps of drones and different structures of cell caps,and a digital permeability instrument was used to detect the air permeability of different cell caps.The results showed that on the seventh day of cell capping in drones,the pore structure with a diameter around0.4-0.5 mm had already formed.Furthermore,the permeability of drone cell caps of Apis cerana cerana was significantly lower than that of worker cell caps of Apis cerana cerana,and that of worker and drone cell caps of Apis mellifera.What＇s more,the drone cell caps had a compact structure.The experiment of artificial cell capping of the drones of Apis cerana cerana showed that the pore of drone cell caps had a certain influence on the development of drones of Apis cerana cerana.
