Toxicidade do pólen de mimosa verrucosa benth., a abelhas operárias africanizadas.

Abstract

The present paperwork aimed to study the toxic effect of the M/mofa vem/cosa Benth anthers macerate., popularly known as Jurema-Branca, about worker bees of Ap/s me///lona. popularly known as africanized bees. The study was made in the Enthomoly Laboratory of the Science and Agroalimentary Technology Center - CCTA, Federal University of Campina Grande - UFCG, Pombal Campus. lo the execution of the work, it was collected flowers of verrucosa Benth., that were put to dry for a period of 48 hours, separating the anthers of the other structures of the flower and macerating them. Then, using the "Candí' diet, it was added three concentrations: 0,25%; 0.50% e 1,0% of the pollens macerate. Young bees of 24 hours of life were used being distributed in 12 boxes of wood containing 20 bees each, totalizing 240 bees. For each concentration and for the witness it was used three repetitions, the boxes were conditioned in B.O.D. greenhouse, under ideal conditions of survival to the bees, to know: temperature of 28 to 32'C and humidity of 70%. After 24 hours it was made the first counting.of dead worker bees, removing the boxes that had dead bees for the period of 21 days. The. resulta were analyzed through the software Prisma 3.0, which also served to the confection of the graphics. By the results it was obtained that the Jurema-Branca may cause the death of the worker bees, because the average longevity considering all the concentrations was of only 6 days, by the step that in the witness the lifetime was of 14,5 days, in average.
