“…The attack manifested itself differently for the planthopper and similarly for the two stink bugs. In case of M. pruinosa, the leaves and shoots were indirectly affected, by the presence of white filaments, according previous mention (Vlad & Grozea, 2016)). In case of stink bugs, both the quantitative and qualitative depreciation of the fruits occurred (Figure 6).…”

“…in the west (Timișoara, Timiș county) (Gogan & Grozea, 2010) expending in other areas (Chireceanu & Gutue, 2011). It is difficult to fight this species, because the nymph stage has some filaments that ensure protection at the same time, but also due to the progressive adaptability to new spaces and plants (Vlad & Grozea, 2016) being adapted to both woody and herbaceous plants (Blidariu et al, 2013), from agricultural areas but also from green areas (Muntean & Grozea, 2021). However, classic methods through chemical and biological control trough using the Neodryinus tiphlocibae parasitoid wasp (Alma et al, 2005) have been brought to attention until now, although the effect is not very clear.…”

After more years since the first notification, the following species of pests Metcalfa pruinosa, Nezara viridula and Halyomorpha halys are still present in agroecosystems in Romania. The high polyphagism, the easy adaptability to new areas and host plant species as well as the lack of a well-defined strategy to fight are characteristics that have contributed to maintaining an active population that still produces damage. Through the present paper, we have proposed to bring attention to their evolution since their first signalling on various plant species from various agroecosystems. We also focused on the current analysis of the numerical level of the active and inactive stages and the damages produced in agricultural and horticultural crops in the west of the country, in period 2020-2022. As a result of the evolution study, it was found that all 3 targeted species are still present on a large number of plant species from agro-horticultural crops composition (both in open or closed spaces). The active (nymphs and adults) and inactive (eggs) stages were observed on the analysed plants and their level was high especially in the species of M. pruinosa and H. halys, while the species of N. viridula species, registered a slight decrease. Thus, the damages produced were commensurate with the numerical level. Continuous monitoring of these highly agile polyphagous pests is necessary to prevent the gradual increase in populations in public places (parks) and the extension to plants in agroecosystems.

“…Metcalfa pruinosa Say it is a species with a high capacity to spread and adapt to the conditions of the new habitats as well as the installation on new host plants. In Romania, after only one year since its reporting in Constanţa County (in 2009) it was also found in the Timişoara area, and then also in the neighboring counties, Arad, Bihor, Hunedoara (Vlad and Grozea, 2016). In 2014 these authors, monitoring the spread of the species in 13 counties in the western part and in the central area of Transylvania, have already reported it in 8 counties, but they did not report it in Sălaj, Cluj, Alba, Mureş and Sibiu counties.…”

Studies Regarding the Attack of Some Invasive Species on Trees and Shrubs from Landscape Arrangements in Cluj-Napoca Municipality

Species of ornamental trees and shrubs are frequently attacked by invasive species recently introduced in Romania. Of these, the species Metcalfa pruinosa Say. (Hemiptera: Flatidae), native to the United States, is widespread. It is a polyphagous species. The attack is manifested in the leaves causing damage to the aesthetic value of the attacked plants. During the 2020-2021, the species of trees and shrubs attacked by Metcalfa pruinosa Say were identified and the frequency and intensity of the attack was determined. The studies were carried out in the spaces see and on the street alignments in Cluj-Napoca. Observations were made on all plant species to determine the frequency of the attacked leaves. The species we reported on 47 species that systematically belong to 23 families. Metcalfa pruinosa Say. was reported on most plants, and the most attacked plants were: Ligustrum vulgare L., Fraxinus excelsior L., Robinia pseudoacacia L., Aesculus hippocastanum L., Acer platanoides L., Buxus sempervirens L., Thuja accidentalis L.

“…All observed plants to be attacked belonged to angiosperms, with the exception of blue spruce (Picea pungens). Vlad and Grozea (2016) observed that conifers are rarely attacked, probably because they have needles or scalelike leaves with thick, rough and waxy epidermis. In Romania the flatid only attacked Pinus strobus, Taxus baccata and Thuja orientalis.…”

Metcalfa pruinosa (Say, 1830) was recorded for the first time in Poland, in the city of Warsaw. This Nearctic species of the Flatidae family was introduced into Europe in the late 1970s and has expanded its range ever since. We provide data on the first record as well as briefly characterize the insect in terms of its diagnostic features, biology and potential harm to agriculture and the environment.
