Resumo:
The aggression of Africanized bees is considered by many as a strong ally
beekeepers to prevent theft of their production. This study aims to assess the
aggressiveness of the bees Apis mellifera L. Africanized in the backlands of Paraiba,
through tests of defensive behavior, for the production of queen bees calm and
productive. The survey was conducted in UFCG - POMBAL - PB County and the
municipalities of Pombal and Sousa in the backlands of Paraiba. Apiaries are
composed of 30 clusters, housed in standard Langstroth hives. Of these, 10 colonies
were randomly selected. The tests were carried out aggression in each hive chosen
in 3 replications, in times of 07:00 and 10:00 hours (H1), from 12:00 to 14:00 hours
(H2) and 15:00 to 17:00 hours (H3), and during winter (April 2012) and dry (August
2012). Aggression was measured by the method of Stort (1974) with some
adaptations ours, where the following observations were made: Time for the fury of
the bees; occur for the first time in a sting suede, number of stings left in suede
trapped in a container circular, Number of bees that attacked after 1 minute; Distance
bees chased the handler, and the time to calm the bees in the colony. Data were
analyzed by SAS statistical software version 9.0 and SigmaPlot for Windows version
12.0. After analysis of normality by the Shapiro-Wilk test, and homogeneity of
variance by Bartlett, the parameters evaluated by analysis of variance followed by
Tukey's test and their interrelationships through the Pearson correlation test. Data
analysis by the method of Ward are represented in a dendrogram. To the fury of
bees observed that during winter in times ranging from 7:00 to 10:00 hours and from
12:00 to 14:00 hours of the day with figures of, respectively, 4.03 and 3.46 s, being
statistically different from those observed in the period from 15:00 to 17:00 (2.56 s).
During the dry season, we observe the shorter infuriating between 12:00 to 14:00
hours and from 15:00 to 17:00 hours of the day (3.93 and 2.76 s), being the period of
greatest aggressiveness of bees. Compared bee behavior between the winter and
dry, we observed that the time infuriating bees did not differ statistically between the
hours of 15:00 to 17:00 hours. Among all analyzed hives observe that they have
characteristics in common, regardless of place of origin and can group them in order
to qualify them as aggressive or tame.
