Toxicidade do pólen de juremas (preta, branca e maliça) sobre operarias de abelhas africanizadas no semiárido paraibano.

Abstract

The present work aimed to evaluate in the toxic effect of pollen Juremas flowers (black, white and malic), belonging to fabaceae family provided the workers' Africanized Apis mellifera in controlled conditions, the pollen was weighed into separate fractions in the concentrations of (0.025%, 0.050% and 0.1%) and added to the water and''cândi'' operaias were distributed together 20 insects per wooden box, with three replicates, totaling 12 240 bees Caxas and these were placed in BOD in temperature adjusted to 32c and 70% humidity, the control group received only''Cândi'' and water. The experiment was conducted in the Agrifood Science and Technology Center, Campus Pombal-PB, belonging to the Federal University of Campina Grande and the experiment in DIC and for data analysis used the parametric test Log Rank Test, the comparison of Survival curves. There was a reduction in the survival of life of bees that were submitted to treatments containing the pollen Mimosa hostilis, Mimosa verrucosa and Pithecolobium dumosum. The control bees remained alive until the 25 days to an average statistical 19 days of survival and those that were treated with pollen concentrations 0.025%, 0.050% and 0.1% had mortality 12,12e 10 days treated with jurema Black, 15,13e 11 treated with white jurema and 15, 14:12 treated with malic jurema. Thus there is a toxic pollen from these plants on bees Apis melífera.O effect Present work aimed to evaluate in the toxic effect of pollen Juremas flowers (black, white and malic), belonging to fabaceae family provided the workers' Africanized bees Apis mellifera under controlled conditions, the pollen was weighed into separate fractions in concentrations (0.025%, 0.050% and 0.1%) and added to the water and''cândi'' operaias were distributed together 20 insects for cash wood, in three repetitions, totaling 12 240 bees Caxas and these were placed in BOD in set temperature to 32c and 70% humidity, the control group received only''Cândi'' and water. The experiment was conducted in the Agrifood Science and Technology Center, Campus Pombal- Pombal-PB, belonging to the Federal University of Campina Grande and the experiment in DIC and for data analysis used the parametric test Log Rank Test, the comparison of Survival curves. There was a reduction in the survival of life of bees that were submitted to treatments containing the pollen Mimosa hostilis, Mimosa verrucosa and Pithecolobium dumosum. The control bees remained alive until the 25 days to an average statistical 19 days of survival and those that were treated with pollen concentrations 0.025%, 0.050% and 0.1% had mortality 12,12e 10 days treated with jurema Black, 15,13e 11 treated with white jurema and 15, 14:12 treated with malic jurema. Thus there is a toxic effect of pollen of these plants on the Apis mellifera bees.
