Resumo:
This study aimed to evaluate the toxic effect of the purple flowers of
Jatropha Africanized bees under laboratory conditions. The experiment was
conducted at the entomology laboratory of the Universidade Federal de Campina
Grande. Campus Pombas - PB, using dried flowers of purple nut-macerated, weighed
in three dHerent fra(iions (0.25%, 0.50% and 1 .0 a%) and added to an artificial diet
known as ''Cândi". 'The fractions were placed in small plastic caps with a small screen
wire covering to prevent the insect drowns when the diet is liquid. The newly
emerged bees were placed in groups of 20 individuais in wooden boxes measuring
11 cm lona x ll enches wide and 7 inches deep, with three repetitions at a
temperature of 32 ' C and 70% RH in greenhouses BOD To perform the analysis
using the nonparametric log rank test for comparison of survival curves. 'The bees in
the control group survived to 25 days, reaching a statistical average of 19 days. The
experimental group treated with 0-25% had average mortality at 13 days, fed at
0.50% showed average mortality of 09 days and who ate diets to 1 .0% of macerateC
flower reached an average mortality of 08 days. The results of the anatysis of data
showed statistically significant differences between treatment and control groups.
v\nth these results we conclude that the mash obtained from the flowers of Jafropha
gossypiiÉo/ia L. is toxic to Africanized honeybees Ax)is me//fãera.
