Survival of Liriomyza huidobrensis outdoors

In 1995, Liriomyza huidobrensis (EPPO A2 quarantine pest) was found on outdoor vegetable crops in northern Germany (Mecklenburg-Vorpommern). The pest was found in 3 ha of field lettuce (probably introduced with the plants) and then spread to broccoli and celery. Lettuce and celery showed severe leaf damage due to high populations of leafminers. Studies were carried out to evaluate the ability of L. huidobrensis to survive outdoors. It was observed that none of the leafminer stages was able to survive winter 1995/96, in this region. Although, this winter was colder than usual, L. huidobrensis would not generally be expected to survive the winter conditions in this part of Germany. In spring 1996, L. huidobrensis was not found again on in the previously infested field.
