Abstract
In the current context of globalization, biological invasion of alien species has an important impact on environment, economics or human health. Particularly, the spread of these species in urban green areas, is problematic due to several reasons. The aim of this research was to report the presence of invasive insects on woody plants in the main parks across Bucharest (namely Alexandru Ioan Cuza Park, Bucharest Botanical Garden, Cișmigiu Gardens, King Michael I Park, USAMV Campus, Youth Park). Field observations were done during the summer of 2019 (July) and the protocols recently developed by the experts from “Marin Drăcea” National Institute for Research and Development in Forestry were used. It was identified twelve invasive insects species: Aproceros leucopoda (Hymenoptera: Argidae), Cameraria ohridella (Lepidoptera: Gracillariidae), Corythucha arcuata (Hemiptera: Tingidae), Corythucha ciliata (Hemiptera: Tingidae), Cydalima perspectalis (Lepidoptera: Crambidae), Dasineura gledithchiae (Diptera: Cecidomyiidae), Eopineus strobus (Hemiptera: Adelgidae), Macrosaccus robiniella (Lepidoptera: Gracillariidae), Nematus tibialis (Hymenoptera: Tenthredinidae), Obolodiplosis robiniae (Diptera: Cecidomyiidae), Parectopa robiniella (Lepidoptera: Gracillariidae), Prociphilus fraxinifoli (Hemiptera: Aphididae).
Highlights
Invasive alien species represent organisms that were introduced by humans outside of their natural environment and which have multiplied and started to have negative effects on the new ecosystem (Williamson and Fitter, 1996; Juliano and Lounibis, 2005; EEA, 2013)
During July 2019, observations were made on the itinerary in the main parks in Bucharest: Alexandru Ioan Cuza Park, Botanical Garden, Cișmigiu Garden, King Michael I Park, USAMV Campus and Tineretului Park
Of all the invasive insect species on woody plants found in the current study, none are new to Romania, all have been reported before in the country through other studies (Olenici and Duduman, 2016; Olenici et al, 2018; Nețoiu et al, 2018; Tomescu et al, 2018)
Summary
Invasive alien species represent organisms that were introduced by humans (deliberately or accidentally) outside of their natural environment and which have multiplied and started to have negative effects on the new ecosystem (Williamson and Fitter, 1996; Juliano and Lounibis, 2005; EEA, 2013). The phenomenon by which these species are introduced, established, spread and have a negative effect on the native species is defined as biological invasion (Williamson and Fitter, 1996; Davis et al, 2000; Lounibos, 2002, Juliano and Lounibis, 2005; Simberloff et al, 2013).
