Toxicologia do pólen da flor de salsa (Ipomoea Asarifolia) sobre a longevidade de abelhas (anis mellífera L.) africanizadas em condições controladas.

Abstract

The present work had for objective to study the toxicity of lpomoea asarifolia R. et Schult for bees Apis mellifera in controlled conditions. The bioensaios were accomplished at the Laboratory of Entomology of the Federal University of Campina Grande, Campus of Dovecote. He/she used poién of lpomoea asarifolia. The polén was weighed in 8 different fractions (0,25%, 0,50%,0,75%,1,0% and 2,5%,5,0%,7,5%,10%) and added to the "candi". you would operate Them recently emerged were selected by the size and coloration, distributed together of 20 insects by wood box measuring 1 1 cm of length for 1 1 of width and 7 cm of height, in three repetitions and the control, perfazendo 27 boxes and 540 labor bees, they were conditioned in B. O. D with adjusted temperature to 32nd C and humídity of 70%. THE group control just received the candi and water. The insecto of the treatment received the cândi with the polén of lpomoea asarifolia. The result of the statistical analysis was obtained in the comparison among the concentrations of the treatment and of the group it controls in the experiment of ingestion polén. For analyses of the data the no-parametric test Log Rank Test was used, in the comparison of the survival curves. It was observed that the survival of the bees was reduced with the use of the diet containing the extracts of polén of 1. asarlfolía.
