Estudo do macerado de flores de jurema preta sobre operárias de abelhas africanizadas em ambiente controlado.

Abstract

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.
