Study On Three New Techniques Of Breeding In Apis Mellifera

The technology of breeding honeybee briefly includes the technique of breeding two-queen colony, adding comb with full-hive or half-hive, fixing and transporting colony quickly. We improved the entrance, body, frame and linker of standard bee-hive, and study the effect of breeding two-queen colony and adding comb with full-hive or half-hive on the spring reproduction with overwinter colonies in Apis mellifera ligustica. After spring reproduction the colonies were modulated to the same level of population, then the effect of breeding two-queen colony on the yield performance of colonies were studied; The effect of the technology of fixing and transporting beehive speedy on the efficiency of transporting were also studied. The results showed that the effect of bee's spring reproduction has increased 11.9% significantly, the output of honey and royal jelly increase 23.8% and 28.8% respectively and the transporting efficiency has raised 178%-275%.We imitated the character of biology in Apis mellifera ligustica and designed a equipment of royal jelly production of larvae-free transferring. Then we studied the factor of the rate of oviposition, the time and period of royal jelly collection and the effect of royal jelly production with improved artifical queen cell. Moreover, we compared the efficiency of arvae-free transfering and larva-grafting on producing royal jelly. The results tell us that the rate of oviposition in queen cell with a little of royal jelly or honey is 97.2% after 24h and the amount of royal jelly in every cell is 1.072g after 6.5d of oviposition, the quality of royal jelly with 5 days is better and the total yield is higher 4% than 6 days royal jelly for 4%, the improved queen cell E is better fit for larvae-free transferring to produce royal jelly. Compared with larva-grafting in producing royal jelly, the yield and the efficiency of larvae-free transferring in producing royal jelly have raised 32.6% and 150% -280% respectively.The queen-cell accepted rate and quality of queens reared by the methods of larva single-transferring (ST), larva double-transferring (DT) and larvae-free transferring were determined in spring and autumn respectively in Apis mellifera ligustica. The experiment results show that the queen-cell accepted rate by arvae-free transferring is very significantly less than ST and DT, while the quality of queens is better than that of ST and DT. The quality of queens reared by ST and DT in spring is higher than that in autumn. No significant difference between the quality of queens with larvae-free transferring in spring and autumn.
