Mating frequency of under desert conditions of Saudi Arabia.

Queen mating frequency is an important reproductive trait of the western honeybee . Yet, it demands more attention when investigated under extreme or confined ecosystems. Queen mating frequency of the Yemeni Honeybee was estimated under Saudi Arabia desert conditions, Riyadh (24°71'36″N, 46°67'53″E). Mating of queens took place after 8-13 days from emergence. Duration of mating flight ranged between 26 and 39 min. Subsequently, six microsatellite loci were used to genotype queen's progeny (n = 30 workers/queen). The average number of drone alleles using workers genotypes ranged between 5.83 ± 0.31 and 6.33 ± 1.09. However, effective paternal allele number was extremely low and ranged between 3.35 ± 0.34 and 3.60 ± 0.40. This relatively low mating frequency of the Yemeni honeybee, , might have striking effect on the overall colony survival. Providentially, this relatively low mating frequency does not impact colonial heterozygosity, shown in this study (0.66 ± 0.07-70 ± 0.04), adversely. These results may affect hive survivability and entails distinctive management practices under such conditions.
