An interesting symposium was held at Koppert Biological Systems in Berkel and Rodenrijs on 'New techniques for better biocontrol: next-generation sequencing, genotyping and experimental evolution in insects and mites'. Guest speakers like Richard Stouthamer and Jack Werren came all the way from the U.S. It was a long day starting from 6 am at Radix building with a bus tour to Koppert, ending at 22:30 after a delicious dinner in an Italian restaurant.
