mellifera L.) Queens in Field Colonies]]>Al-QarniAbdulaziz S.SmithBrian H.CobeySusan W.122003617Apis mellifera queens were reared to evaluate the performance of Naturally Mated (NM) and
instrumentally inseminated (II) queens, using Doolittle grafting method. A group of twelve
queen cells was introduced to five frames nucleus colonies and virgins allowed to mate
naturally. A second group of 14 queen cells was confined to cages and instrumentally
inseminated once with 8 μl of semen and placed back to their assigned nucleus colonies. At
oviposition, nucleus colonies for both groups were transferred into a standard Langstroth
hive filled with empty combs and all colonies were allowed to build up naturally into full-size colonies. A perusal of the data presented a slightly higher survival rate in NM queens
but binary logistic regression test revealed no significant differences between the survival
rates of both NM and II queens that ended up with 5 NM (41%) and 3 II (21.4%) queens after
23-months. A detail probe of ANOVA also indicated no significant difference in brood
production which were recorded 1274.4 and 1304.3cm2 2-months after colony establishment,
1585.2 and 1534.6 cm2 during April 1997 and 1674.9 and 1541.5cm2 during spring 1998 for
NM and II queens respectively. Likewise, honey production for NM remained statistically
at par with that of II queens and was recorded 251.7 and 241.1 lbs. during fall season 1996
and 314.2 and 297.5 lbs. during fall 1997 for NM and II queens respectively.]]>Cobey, S.,1983123108111Doolittle, G.M.,1889Espelie, K.E., V.M. Butz and A.
