The biology of Thrips tabaci Lind was studied during the winter 1999-2000 and 2000-2001 in winter leek crops at Kruishoutem and Sint-Katelijne-Waver. The numbers of larvae decreased from November while the numbers of adults increased. Only overwintering adults were found during January, February and March on the leek plants. From the beginning of April, larvae were again observed in the winter leek crops. Weather permitting, the adults of these "spring generation" immigrate into the leek seedbeds or early leek crops.
