Carrot psyllid Bactericera trigonica belongs to the family Triozidae, superfamily Psylloidea, order Hemiptera. Together with onion psyllid (B. tremblayi) and potato psyllid (B. nigricornis), it is a member of the complex Bactericera nigricornis Foerster with morphologically and bioecologically very similar species. It was originally described by Hodkinson (1981) as Trioza trigonica based on the analysis of adults collected from the carrots in Portugal, Italy, Cyprus, Turkey, Egypt and Iran. Later it has been transferred to the genus Bactericera together with the two other species from this complex. Adults and larvae B. trigonica, feed on carrot leaf and other Apiaceae. If they appears in large number, they can lead to chlorosis and leaf yellowing, which causes a yield reduction. Besides direct damage, its vector role of bacteria “Candidatus Liberibacter solanacearum” has been determined, which leads to root proliferation and weakening of plants from Apiaceae family due to chlorosis. Ca. Liberibacter solanacearum has been known in North Africa and New Zealand for a long time on plants from Solanacae family, potato in the first place, while in Europe it has been determined on carrot and cellery for the first time, with B. trigonica as its vector. The presence, biology and harmfulness of B. trigonica in the region of Serbia were studyed in the period from 2014 to 2017. It was found in 2014 for the first time and since then, its presence has been determined in all researched localities, during the whole vegetative period of carrot. Besides carrot, B. trigonica has been registered on celery, parsley and wild carrot as well. It has a several generations per year, overwintering as adults.
