Africanized bee

Multiple regression analysis using the stepwise method with the selected models for Africanized honeybee colonies with queens selected for honey and royal jelly production in the experiment I.

Mean values and standard mean values and standard deviation, five reviews related to each of the hives were submitted for each variable of defensive behavior in africanized honeybee workers (Apis mellifera L.) from Dourados-MS, Brazil.

From each study site, three European and three Africanized honeybee colonies were randomly selected for pollen load sampling.

To help avoid stings from the Africanized honeybee, Dr.

Colonies (n = 90) of the Africanized honeybee Apis mellifera, 40 colonies producing honey and 50 producing royal jelly, were subjected to monthly tests of infestation and invasion from February to December 2009.

Therefore, this study aimed to estimate queen weight at emergence and morphometric characteristics of the wing, abdomen and thorax of Africanized honeybee queens regarding storage techniques after emergence in queen banking or incubator.

The Table 5 shows the means and standard deviation of the number of grafted larvae in cup bar frame in the upper, middle, and lower (%), total weight of royal jelly produced by treatment (g), amount of royal jelly per cup (mg), F values with respective probabilities (P), coefficients of variation (CV%) of 20 Africanized honeybee colonies supplemented and not supplemented (controls).

"Surprisingly, we found that fewer Africanized honeybees learn to associate an odor with a reward.

After all, killer bees, or Africanized honeybees, are a result of a genetic experiment gone wrong.

Beekeepers got bad press after "Killer Bees," which were actually Africanized honeybees, were accidentally released into the wild by a Brazilian scientist in 1956.

Since the early 1980s, most of the winged visitors there have been Africanized honeybees. To probe their impact on coffee growing, Roubik monitored berry yields from blooms pollinated with and without the help of bees.

Martin was called in to exterminate the six-foot, 300-pound hive, which was home to 60,000 Africanized honeybees (AHBs), commonly known as "killer bees." Unlike their subdued cousin, the European honeybee, AHBs are viciously territorial: Take one step too close to a colony and the bees attack!

Feral European honeybees are also being displaced by aggressive Africanized honeybees, which can take over hives.

Africanized honeybees look like the European honeybees now commonly found in our gardens, and like their relatives, they make honey.

As the Africanized honeybees are sensitive to environmental changes (Amdam et al., 2005), climate variables are directly related to the productivity of the colony (Costa et al., 2007), since they are related to the energy expenditure to control foraging activity (Biesmeijer & de Vries, 2001; Gruter & Farina, 2007).
