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.
Epicometis hirta Poda. is a dangerous pest which can be observed on annual crops and also on fruit tree species. The adult is a beetle can be easily recognized due to existing pubescence found all over it's body. The pest causes damage by consuming the reproductive organs of flowers. Adults are phytophagous and feed on leaves and flowers of plants such as orchard trees, cereals or ornamental plans. The timeing chemical control against this species is very difficult considering that the moment of sprays application is during bloom,thus the pollinating entomofauna is affected. Therefore the need to develop alternative control methods is highlighted. Semiochemical products represent a method of perspective whereas involve only the target species. For this purpose the team of entomology discipline along with Institute of Chemistry "Raluca Ripan"colegues, tested the attractiveness of two new synthetic products which were placed in three types of traps (Type 1, Type 2, Type 3). Experiments were located in UASVM Cluj Napoca Orchard, fruit tree farm Steluţa and fruit tree farm Agroindustriala Cluj Napoca. The best results were obtained by Type 1 trap, in all three locations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
