Africanized Bees

African honey bees, Apis mellifera scutellata (formerly adsonii) were imported to Brazil in 1956 to introduce a strain of bees with increased honey production which were more suited for the tropical climate.1,2 A year later, 26 African queen bees and their accompanying colonies accidentally escaped.1,2 The African queen bees soon began mating with established European bee races resulting in the hybrid Africanized honey bees.2 Like the pure African bees, the Africanized bees are more defensive with a greater tendency to sting than European bees.3 They respond quickly to the slightest disturbance of their nest and can send out many thousands of bees.

Different Levels

Different levels of infestation with the mite Varroa jacobsoni have been observed in the various Apis mellifera races. In general, bees of European races are more susceptible to the mite than African honey bees and their hybrids. In Brazil honey bee colonies are not treated against the mite, though apparently both climate and bee race influence the mite infestation. Six mixed colonies were made with Italian and Africanized honey bees. The percentage infestation by this parasite was found to be significantly lower in adult Africanized (1.69 ± 0.44) than Italian bees (2.79 ± 0.65). This ratio was similar to that found in Mexico, even though the Africanized bees tested there had not been in contact with varroa, compared to more than 20 years of the coexistence in Brazil. However, mean mite infestation in Brazil on both kinds of bees was only about a third of that found in Mexico.

AbstractIn a 5-year study at Beaverlodge, Alta. (lat. 55° N.), 1-kg packages of honey bees hived in mid-April (10–23 April) produced more honey than those hived in early May (5–13 May) in only 2 years. The major nectar flows ranged from 22 June to 22 August.The rate of brood rearing as determined by egg-laying of queens and the build-up as shown by adult bee populations at various periods after hiving increased progressively with delay in hiving dates which ranged from 4 April to 3 May, and were attributed to the more favorable climate of the later hivings. Adult bees in excess of 1 kg per package did not increase egg-laying of queens or the build-up of colonies.Restriction of daylength by 6 hours per day for 8–9 weeks had no effect on colony brood rearing or build-up. Restriction of daylength to 6.5 hours per day for 7 weeks caused a small initial reduction in egg-laying in the first brood cycle (1.5 weeks after hiving) but no differences were noted later, either in egg-laying at 4.5 weeks or adult populations at 9.5 weeks. When colonies were in complete darkness for 3 weeks, egg-laying was reduced 35 to 60%.

Effect Of Feeding

The disruption of nectar and pollen providers for honey bees is currently a problem in the availability of natural feed. During the dry season, alternative feed sources are given to bee colonies to increase honey production. The purpose of this study was to determine the effect of feeding of sugarcane juice (Saccharum officinarum) on the sugar content of Apis mellifera honey with a comparison of the original feed in the form of nectar and pollen. This research was conducted at Batu city beekeeping. The method in this study used 4 treatments and 6 replications using the ANOVA test which was processed using SPSS 16 Analysis of the results obtained were PS 881 Sugar Cane, BL Sugar Cane, PSJK Cane is the same, but different from the control. Sugar cane has an influence on increasing sugar levels in honey.  Keywords: Artificial feed, refractometer ABSTRAK Terganggunya penyedia nektar dan polen bagi lebah madu saat ini merupakan permasalahan dalam ketersediaan pakan alami.
