Abstract:Transgenic cotton plants (Bacillus thuringiensis Berliner (Bt)) has significant influenced the integrated pest management around the world. In Colombia, Anthonomus grandis Boheman and Spodoptera complex are currently considered the main pests in cotton crops. Therefore, this study evaluated the effect of Bt (Cry1Ac and Cry2Ab) and non-Bt cotton on the population fluctuation during two years in Tolima region. A Pearson correlation matrix was carried out between the pest variables and yield, while climatic varia… Show more
