“…However they did calculate the parasitism at a rate of 61%. More recently, in Mexico, Ávila‐Rodriguez et al (2015) calculated a rate of parasitism for C. lucifluella in pecan orchards of 0%–23.3% depending on the location and sampling date. They identified eight different genera, out of which Baryscapus and Quadrastichus (Hymenoptera: Chalcidoidea: Eulophidae) were the most abundant.…”

“…The leafminer is described as having a high mobility and dispersal capacity, which can be seen by its widespread presence in the newly occupied territories (Bernardo et al, 2015; Takács et al, 2020). The study of Poggetti et al (2019) in Italy shows that altitude is a factor limiting the moth's distribution, most signs of pest damage being found on walnut trees at low altitudes up to 400 m, occasionally at 400 m and absent at altitudes higher than 600 m. Outside Europe there was a report in Mexico in 2012 (Ávila‐Rodriguez et al, 2015) when the species was found in pecan nut orchards causing moderate damage.…”

“…Coptodisca lucifluella is presently considered a minor pest of common walnut ( Juglans regia ) in Europe and pecan ( Carya illinoinensis ) in North and South America (Ávila‐Rodriguez et al, 2015; Bernardo et al, 2015; Davis, 1998; Heyerdahl & Dutcher, 1990; Payne et al, 1972; Takács et al, 2020). The damage on host plants consists of mines on the leaf surface and mines with perforations, caused by larvae which feed on the mesophyll of leaves, leaving behind the two epidermises.…”

Following its first report in Romania in August 2022, more data regarding the walnut shield bearer Coptodisca lucifluella was collected. The leafminer moth is an invasive species of North American origin that entered Europe in 2010 (in Italy), and then spread to Hungary, Ukraine, Bulgaria and Romania. It is not an economically important pest alone but in association with other stresses affecting walnut trees, over time, it could contribute to their premature decline. In Romania, C. lucifluella was identified in 24 localities in eight counties and in Bucharest. The main host is the common walnut, Juglans regia (L.), while secondary hosts include the black walnut Juglans nigra (L.), Caucasian walnut Pterocarya fraxinifolia (Lam.) Spach and the pecan nut tree Carya illinoinensis (Wangenh & K. Koch). All walnut trees inspected in 2022 were affected by the leafminer to a greater or lesser extent. The proportion of attacked leaves per tree, evaluated in Northern Bucharest and Moara Domnească in the south of the country respectively, was 40% and 41% in August and increased to 69 and 93%, in October. Inside the mines, our team discovered a significant number of parasitoid larvae and pupae. These were kept in the laboratory until the emergence of adults which were photographed, but so far remain unidentified. The rate of parasitism was 17.4% in N. Bucharest and 31.8% in Moara Domnească.

" The invasive species Coptodisca lucifluella, also called the walnut shield bearer is recorded for the first time in Romania in this report. It is a leaf miner of North American origin, having been discovered for the first time in Europe (Italy) in 2010. Since then it has been confirmed in other three European countries, Hungary (2017), Ukraine (2019) and Bulgaria (2020), and now in Romania. In its native habitats, the species is known to be specialized on woody plants from the family Juglandaceae, genus Carya, in particular the pecan nut tree, Carya illinoinensis (Wangenh.) K. Koch. In the newly occupied territories in Europe, the moth was reported mainly on Juglans spp., especially J. regia (L.) (with very few instances on Juglans nigra (L.), Carya spp. and Pterocarya spp.). In August 2022, leaves of common walnut (J. regia) with mines of C. lucifluella were collected in Southern Romania (Bucharest, Ilfov and Giurgiu Counties) and Western Romania (Arad County). The walnuts were in cities, rural areas, alongside roads and walnuts spontaneously grown in vineyards, at altitudes from 60 to 200 m a.s.l."
