First record of the onion psyllid Bactericera tremblayi (Wagner, 1961) in France (Insecta: Hemiptera: Sternorrhyncha: Psylloidea), new symptoms on leek crops and reassessment of the B. nigricornis-group distribution
EPPO Bulletin 42 (3), 585-590
Abstract: The triozid Bactericera tremblayi, or onion psyllid, is recorded for the first time from France, and is associated for the first time with important damage on leek crops in several regions of the country. We compare the morphology of this species with the two other species of the B. nigricornis-group, in order to avoid misidentifications, and illustrate the different stages of B. tremblayi. The published distribution of the three species is summarised and updated based on collection data, and the presence of B. tremblayi and B. trigonica in Jordan and Spain (Canary Islands) respectively, is also recorded for the first time.
