浙农大1号意蜂和本地意蜂发育时龄的研究

Study on development time (in hours)of Italian Bee

本文对浙农大１号意蜂（Ｅ_ａ）和本地意蜂（Ｅ_ｂ）的工蜂、蜂王、雄蜂的发育时龄（从卵到成虫羽化）进行了研究。其结果是：Ｅ_ａ和Ｅ_ｂ的平均发育时龄，工蜂分别为５０４．７和５０６．８小时，蜂王分别为３８７．５和３９５．５小时，雄蜂分别为５８１．５和５８５．６小时。Ｅ_ａ和Ｅ_ｂ三型蜂的发育时龄均存有差异，Ｅ_ａ的工蜂、蜂王、雄蜂发育时龄分别比Ｅ_ｂ缩短２．１、８．０和４．１小时。此外，还发现受精卵的胚胎发育比未受精卵快。

The development time (from egg laid to emergence) of worker, queen, drone of Zhenongda-l (Ea) and China local Italian Bee(Eb) were saudied. The result is as follows: The average total development time of Ea and Eb worker are 504. 7 and 506. 8 h; queen are 387. 5 and 395.5h;drone are 581. 5 and 585. 6 h respectively. The result showed that there are some differences in development time of three castes betreen Ea and Eb. The development time of worker, queen and drone of Ea is respectively 2. 1, 8. 0 and 4.1h shorter than that of Eb. In addition, the embryonic developmenttime of fertilized egg is found to be shorter than that of unfertilized egg.
