Effect of "stryphnodendron spp. tanino on apis mellifera l. (africanized bees)" longevity

The barbatimão (Stryphnodendron spp.) tanino had a well know toxicity effect on honeybee (Apis mellifera), having a cause of monetary lack, intoxication, and mortality. This work had the goal to study the mortality of honeybee fed by candi type paste with different concentrations of tanino. It was utilized a completely casualized experimental design with three levels of tanino (1.25; 2.50; 3.75 percent), and a control group without tanino (0.00 percent), applied toward a candi type paste, for 12 days of experimental period. Semiparametric and parametric models of survival analysis were utilized to study the mortality, where the tanino concentration was the independent variable and time to death the dependent variable. Non-parametric and parametric methods were utilized to compare the similarity between treatments. All levels of tanino influenced mortality. The levels of 1.25 percent and 2.50 percent were not statistically different, for both non parametric and parametric models. The Weibull model was considered the best model. It could be possible to conclude that rising levels of tanino in feeding honeybee grew mortality considerably, reducing its time life
