The paper “The impact of secondary pests on Bacillus thuringiensis (Bt) crops” produced within the project AMIGA, has been recently published on Plant Biotechnology Journal (2015). The paper has been produced by the following authors: Rui Catarino, Graziano Ceddia, Francisco J. Areal and Julian Park (AMIGA partner: University of Reading).

The study focuses on the development and impacts of secondary pests on Bt crops. The researchers find that the causes for secondary outbreaks in Bt crops are reduction in broad-spectrum insecticide applications, reduction of natural enemies and species replacement.  However, the authors conclude that regardless of the causes, if non-susceptible secondary pest populations exceed economic thresholds, farmers are likely to use insecticide spraying as their immediate solution.
