Resumo:
A (Mimosa hostilis Benth) known as myrtle. is present throughout the semi-arid
region of northeastern Brazil, and its importance in the share of land cover
along with other vegetables. It is not considered potentially toxic to pets,
anyway, we decided to test the effect of the macerated dried flowers containing
pollen of this plant along with an artificial diet type "Candi" offered the
Africanized bees in the laboratory under controlled conditions according to the
time of flowering and the presence of bees on your flowers. In the
concentrations used were 0.25%, 0.50% and 1 .0%. The newly emerged bees
were placed in groups of 20 subjects for wooden boxes measuring 1 1 cm lona x
l lcm wide and 7 inches deep, with three repetitions at a temperature of 32 ' C
and 70% RH in an environmental chamber To perform the analysis using the
nonparametric log rank test for comparison of survival curves. The bees in the
control group survived until the 25 days, reaching a statistical average of 19
days. The experimental group treated with 0.25% had average mortality at 12
days, 0.50% had fed on average 12-day mortality and those who ate diets to
1 .0% of macerated flower reached an average mortality of 10 days. The results
of the analysis of data showed statistically significant di#erences between
treatment and control groups. With these results we suggest that the macerate
obtained from flowers (Mimosa hostilis Benth) is toxic to Africanized honeybees
Apis mellifera.
