【摘要】 1997～ 1999年在皖中和皖西、皖南山区对意大利蜜蜂 (ApismelliferaLigusticaSpi.)和中华蜜蜂(ApisceranaceranaFeb .)种群数量动态进行系统观察研究 .结果表明 ,蜜蜂种群数量明显受气候和蜜粉源植物的影响 ,周年呈现“两高”(春、秋 )和两低 (夏、冬 )的变化模式曲线 ;意大利蜜蜂春繁及秋季更新速度明显快于中华蜜蜂 ,但越夏效果不及中华蜜蜂 .意大利蜜蜂的性比值为 (314.4± 2 89.9)∶1～ (32 9.4± 30 5 .8)∶1,中华蜜蜂为 (334.2± 2 35 .5 )∶1～ (413 .1± 377.2 )∶1,雄蜂呈季节性出现 .蜜蜂种群内年龄组配在不断变化 .更多还原

【Abstract】 Systematical observations and researches were conducted on the population size dynamics of Apis mellifera Ligustica Spi. and Apis cerana cerana Feb. in Wanzhong,Wanxi and Wannan mountainous area in Anhui Province in 1997～1999. The results showed that the bee population size was influenced by climate and flower fertility,which was higher in Spring and Autumn,and lower in Summer and Winter. The propagation and renewal of A. mellifera in Autumn were quicker than those of A.cerana cerana ,while the effect of overcoming Summer was inferior to that of Apis cerana cerana . The sex ratio of A. mellifera was (314\^4±289\^9)∶1～(329\^4±305\^8)∶1,and that of A. cerana cerana was (334\^2±235\^5)∶1～(413\^1±377 2)∶1. The birth of drones was seasonal,and the age structure of each bee population was variable.更多还原
