Modern genetics arose more than a century ago, thanks to the experiments of a docile animal, the fruit fly. Its short life cycle, small size and low maintenance cost in the laboratory make it an exceptional model for scientific research. But other insects are not so kind to humans and cause all kinds of pests and diseases. Insecticides are not the ideal solution and fortunately new methods are emerging such as biological and genetic control of populations… An international team with the participation of the Institute of Evolutionary Biology (CSIC/UPF) has developed the DIPA-CRISPR method, which Uses this gene editing technique to modify the genome of insects. We spoke with the researcher Maria Dolores PialachsStudy co-author.
