Abstract. The rst records of Leptoglossus occidentalis for Finland are reported. Information on the
distribution of the species in Europe, in particular in its northern part, is summarized.
Key words: Baltic states, distribution, Europe, Hemiptera, invasive species, Scandinavia.
Resumen. Se presentan las primeras citas de Leptoglossus occidentalis para Finlandia. Información
acerca de la distribución de la especie en Europa, particularmente en su parte norte, es resumida.
Palabras clave: Distribución, Escandinavia, especie invasora, Europa, Hemiptera, países bálticos.
Since its rst appearance in Italy in 1999, the highly dispersible Nearctic coreid
Leptoglossus occidentalis Heidemann, 1910 has colonized nearly all of Europe (van der
Heyden 2019; van der Heyden and Zettel 2019).
In Northern Europe, L. occidentalis has been reported from Denmark (Buhl and
Stephensen 2009), Norway (Mjøs et al. 2010) and Sweden (Lindelöw and Bergsten 2012) in
Scandinavia as well as, very recently, from Lithuania in the Baltics (Karalius and Karaliūtė
2019) so far.
Now, the presence of the species in Finland can be reported: On 22-XI-2018 and 23-XI-
2018, Marja Hallikainen photographed at least one specimen of L. occidentalis in the area
of Turku in Southwest Finland. Nearly one year later, on 29-X-2019, Virve Mäkelä found
another specimen in Kotka in South Karelia. A photograph of the specimen was taken by
Petri Metsälä. Data on these ndings were uploaded to the online database Laji. (2019).
Prior to these ndings, a newspaper article about a specimen of L. occidentalis which
had been accidentally introduced to Finland and was found alive under the engine hood
of a car, very likely imported from Germany, was published in the Finnish newspaper
Aamulehti (Manninen 2017).
As L. occidentalis has not been reported for Finland in scientic publications yet, the
records reported in this note are the rst ones for the country.
As L. occidentalis is present in Finland, Lithuania and Russia, ndings of the species
in the Baltic states Estonia and Latvia as well as in Belarus can be expected in the near
future.

Article
The article presents new data on the distribution and acclimatization of an alien species of the American coniferous bug ( Leptoglossus occidentalis Heidemann, 1910) from the European part of Russia. This bug was discovered in the autumn of 2019 on the territory of the city of Voronezh in the Arboretum of the Voronezh State University of Forestry and Technologies. Currently, L. occidentalis spreads on the territory of Russia only in an urban environment, where it finds optimal environmental conditions (suitable temperature, humidity and shelter for winter locations). Surveys of a number of park and forest park zones, squares and separately growing coniferous trees conducted in 2019-2020 in Voronezh did not reveal the presence of this species. At the moment, in the conditions of the Voronezh region, the center of the spread of this bug is located only in the Arboretum of the Voronezh State University of Forestry and Technologies. In 2020, an increase in the number of the identified group of L. occidentalis was recorded. Further spread of the bug is predicted on the territory of Voronezh. At the moment, no danger to conifers in the European part of Russia from L. occidentalis has been identified and is not yet expected, but constant monitoring of the detected group is required.

Mediterranean stone pine nut is appreciated for its high economic and nutritional value. Starting in 2012, Pinus pinea nut production declined throughout the Mediterranean area. The dry cone syndrome associated with this decline and the introduction of Leptoglossus occidentalis occurred simultaneously. This study aims to evaluate potential reasons behind the decline in pine nut production in Lebanon, considering climatic factors and the invasion of L. occidentalis. Correlation analysis was used to examine a potential relationship between cone yield and the percentage of damaged seeds per cone. Climatic variables were also tested. Two time periods were considered for analysis: before and after 2012. Cone production and the percentage of damaged seeds were negatively correlated (r = 􀀀0.42). From 2012 to 2017, cone production declined by 50% and the percentage of damaged seeds increased on average from 3% in 2012 up to 60% in 2017. Correlations were detected between cone production and the temperature of the hottest three months of the year of harvesting, and between cone production and average temperatures during the year of cone initiation. A conjunction of factors that include L. occidentalis and climatic factors might have affected the pine nut production in Lebanon.
