Modelos de sobrevivência de abelhas africanizadas submetidas a dietas com soja e milho transgênicos.

The feeding of bees is an important factor for their survival, and currently, the use of transgenics is common among producers, since the use of these has reduced production costs, however, there is a great debate as to whether transgenics can harm pollinators. that are in farming regions. Thus, the objective was to evaluate the longevity of Apis mellifera bees using different compositions of transgenic and conventional soy and corn diets, foods that can be substitutes for pollen as a protein source for the hive. For that, the theory of Survival Analysis was used, where the data were constituted by interval censorship, because the time of death is not exactly known. The survival function was estimated using the Weibull regression model with the presence of two covariables: whether the diet is transgenic or not, and the protein content. The adequacy of the model was verified by the graphs of the linearizations using a script developed for the Survival package of the R software, in addition to carrying out the likelihood ratio test at 1% probability, concluding that the presence of the two covariables in the model is significant. In this way, the survival curves of the bees and the estimated risk were constructed, concluding that the GM foods did not have a negative effect on the survival of the bees. [ABSTRACT FROM AUTHOR]
