中文摘要：

以中华蜜蜂（Apis cerana cerana）为实验材料,对蜂群中蜂王产的受精卵（QFG）、蜂王产的未受精卵（QUG）和工蜂产的未受精卵（WUG）3者之间的自然孵化率进行了比较研究。结果表明：在有王群内,QFG、QUG和WUG自然孵化率分别为97.33%±2.42%、97.63%±3.04%和97.41%±2.06%,3种卵孵化率差异不显著（P〉0.05）;在无王群内,QFG、QUG和WUG自然孵化率分别为54.22%±6.52%、55.33%±6.47%和54.67%±7.04%,3种卵孵化率差异也不显著（P〉0.05）;然而3种卵的孵化率在有王群内明显高于无王群内,两者之间差异极显著（P〈0.01）。

英文摘要：

The nataral hatching rates of the fertilized- eggs laid by queens（QFG） , the unfertilized- eggs laid by queens（QUG） and the unfertilized- eggs laid by workers（WUG） in the colonies of honeybee, Apis cerana cerana were campared. The results showed that： in the queen - right colonies, the hatching rates of QFG, QUGand WUGwere97.33% ±2.42%,97.63% ±3.04% and 97.41% ±2.06%, respectively, but 54.22% ± 6.52% ,55.33% ± 6.47% and 54.67% ± 7.04% , respectively in the queenless colonies, there was no significant difference（ P 〉 0.05）among the hatching rates of eggs in queen -right colonies or queenless colonies. However, there was remarkable difference（ P 〈 0.01 ） between the queen - right colonies and queenless colonies in the hatching rates of QFG, QUG and WUG,they were higher in the queen - right colonies than those in the queenless ones.
