“…Apiculture in Brazil is based on the well adapted and productive Africanized honeybee (Silva and Freitas, 2004). The world leaders in honey production are China, USA, Argentina and Mexico (Bölke and Palmeira, 2006).…”

Genetic parameters for five traits in Africanized honeybees using Bayesian inference

et al. 2013

Heritability and genetic correlations for honey (HP) and propolis production (PP), hygienic behavior (HB), syrup-collection rate (SCR) and percentage of mites on adult bees (PMAB) of a population of Africanized honeybees were estimated. Data from 110 queen bees over three generations were evaluated. Single and multi-trait models were analyzed by Bayesian Inference using MTGSAM. The localization of the hive was significant for SCR and HB and highly significant for PP. Season-year was highly significant only for SCR. The number of frames with bees was significant for HP and PP, including SCR. The heritability estimates were 0.16 for HP, 0.23 for SCR, 0.52 for HB, 0.66 for PP, and 0.13 for PMAB. The genetic correlations were positive among productive traits (PP, HP and SCR) and negative between productive traits and HB, except between PP and HB. Genetic correlations between PMAB and other traits, in general, were negative, except with PP. The study permitted to identify honeybees for improved propolis and honey production. Hygienic behavior may be improved as a consequence of selecting for improved propolis production. The rate of syrup consumption and propolis production may be included in a selection index to enhance honeybee traits.

“…Offspring abundance is associated with the type of resources (Mattila et al, 2001), and reductions in the brood rearing areas occur under conditions of limited food supply (Costa et al, 2007;Vidal et al, 2008;Genersch et al, 2010). The egg laying behaviour of the queen, in turn, depends on several factors, including the availability of areas in the brood frame and the balance between food resources and adult bees in the hives (Silva & Freitas, 2004).…”

“…Population growth is greater in hives with greater availability of energy resources (McNally & Schneider, 1992;Silva & Freitas, 2004). Vidal et al (2008) reported that the queen lays more eggs in periods with greater availability of food, pollen, and nectar (Costa et al, 2007), particularly of nectar.…”

The objective of this work was to evaluate the variations in the stored food resources and in the number of immature bees in Apis mellifera hives used for apple (Malus domestica) pollination. The study was conducted in the municipality of Vacaria, in the state of Rio Grande do Sul, Brazil, with 40 hives, over two consecutive harvests. The evaluations were done in the hive brood frames before, during, and 45 days after a pollination period, by interpreting photographic field records. Before being transported to the orchards, the bees foraged primarily in areas with native forest or canola (Brassica napus) crop, in 2014/2015, and with native forest or eucalyptus (Eucalyptus sp.) reforestation, in 2015/2016. In both harvests, the percentage of food resources (honey and pollen) stored in the hives reduced significantly between the pre- and post-pollination periods, but there was no significant difference between the pollination and post-pollination periods. The greatest reduction in the storage of these resources was observed in the hives from the canola crop, which had a large supply of floral resources compared with the apple orchards. The hives most susceptible to population variations within the apple orchards are those from the canola crop, whereas those from areas with a lower food supply (forest and eucalyptus) show population gains in the apple orchards.
