Abstract

This work aimed to evaluate the toxic effect of pollen grains Cohesive / Diria param / da / fs Tu / popularly known as. catingueira. at mortality of .4pis me // faena workers, known as Africanized bees. The work was carried out at the Entomology Laboratory of the Science and Agri-food Technology - CCTA, Federal University of Campina Grande - UFCG, Campus Pombal. For the execution of the work, flowers from the Cohesive / p / n / a pyramfda # s Tu / leaving them to dry for a period of. .48 hours, separating the anthers from the other structures of the flower and macerating them. Using the a diet known as "Candí", was added in three concentrations: 0.25%; 0.50% and 1.00%. It was used young bees, with 24 hours of life, which in which were divided into 12 wooden boxes together, in each box were 20 bees were placed, reaching a total of 240 worker bees. They were distributed in three repetitions. more the witness, being conditioned in a B.O.D. greenhouse, leaving the bees in ideal controlled conditions, with the temperature from 28 to 32'C, humidity of 70% and photoperiod, after 24 hours. the first collection of information related to the mortality of. workers with pollen toxicity. ' data collection lasted for 21 days. The results were obtained using the GraphPad Prism 3.0 software, which performed the statistics and the creation of graphs.
