Resumen:
Cacesa/o/rl/a param/da//s Tul. Legum family. Caesalpinioideae catingueira known as.
is present throughout the semiarid region of northeastern Brazil, and its imDortance ir'
the participation of band cover along with other vegetables. It is not considerei
potentially toxic to sets. even se. we chose to test the effect of the mash of drlec
flowers containing pollen of this plant next to an artificial diet type "Candi" offered tne
Africanized bees in controlled laboratory conditions according to of flowering time
ana the presence of bees on your flowers. In the concentrations used were 0.25%,
ú.50% and 1.0%. Newly emerged bees were placed in groups of 20 individuais of
wooaen boxes measuring ll cm long x llcm 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 used the nonparametric test 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 were treated with 0.25%
average monaiity for 08 days, fed the 0.50% experienced mortality averages 05 days
and those who ate diets to 1 .0% of macerated flower reached an average mortality of
05 days. The results of analysis of data showed statistical differences between
treatment and control groups. With these results we suggest that the macerate
obtained from the flowers of Caesalpinia bracteosa is toxic to Africanized noneyDees
Apis mellifera.
