Pest control with genetically modified insects

To control pests without pesticides, genetically modified organisms of the same species could be used. The latter carry a gene that is passed on with above-average frequency via sexual reproduction. This gene possesses traits that directly weaken the pest, or prevent pathogens from being transmitted. But how can the environmental impact of such gene-drive elements be recorded and assessed? Experts from Agroscope have authored a concept study on this topic.
