Abstract


In landscaping, one of the frequently used plants is Buxus sempervirens L. The aesthetic value of these plants are often affected by the pests species that attack the leaves. The main species that attacks the Buxus spp. plants are: Monarthropalpus buxi Geoff., Psylla buxi L. and Cydalima perspectalis Walker. The attack of these species cause the drying of the plants.The Box Tree Moth, Cydalima perspectalis Walker., is a new species, on the European continent, being first recorded în 2006. In Romania, this species was reported in 2010, near Bucharest, from where it has been spread throughout the country. In Cluj has been reported in 2015. For establishing  some control strategies, for this, it is necessary to know the bioecology of this species, depending on the specific environmental conditions of each area where the attack is present. In 2016 we have started the investigations to study the biological cycle, in Cluj area. The investigations were conducted in the laboratory and on the campus of UASVM Cluj-Napoca. In the investigated area, the species develops two full generations, and the third generation is partial. The adults of hibernating generation fly in the first decade of June until the first decade of July. Summer generation adults fly from the first decade of August, creating the second generation and the adults who establish the third generation (partial generation) fly in the second half of September. The incubation is between 5-6 days. Larval stage is between 29-38 days, pupal stage last from 10 to 14 days.
