“…Several independent introduction events of WCSB population are suspected in Europe. The first one was observed in northern Italy in 1999 and the second one in the English Channel in 2007 (Lis et al 2008). Recently, two major invasion events have been detected in the Iberian Peninsula (Gallego et al 2013).…”

Leptoglossus occidentalis, a species native to North America, has been expanding through European conifer forests. The fast spread across the European continent demonstrates its great invasive potential and poses a threat to conifer seed orchards. To better understand its potential distribution and population growth in infested regions, the temperature-dependent development in laboratory as well as life history, phenology, and winter survival were investigated in southern Slovakia during 2009-2011. The lower temperature thresholds to complete embryonic and postembryonic development estimated with the linear model were 13.38 and 14.37°C, respectively. The number of degree-days required for completion of development from egg to adult estimated by the linear model was 533°C. Overwintered adults or late nymphal instars became active in mid-March, oviposition was not observed before mid-April, and nymphs passing through five stages reached adulthood after mid-July. Individual females laid on average 31 eggs (max 78). The second generation started in August but did not complete its development till winter, although part of the 5th instar nymphs did survive until spring. Using temperature data of 41 localities across Europe and cumulative degree-days for complete life cycle, a prediction of the potential number of generations per year was made. In conditions of southern Slovakia L. occidentalis was univoltine, but up to four generations per year were estimated depending on the locality in Europe.Keywords Western conifer seed bug Á Life history Á Phenology Á Degree-days Á Mlyňany Arboretum Key message• Leptoglossus occidentalis is a pestiferous invasive insect feeding on conifer seeds which currently spreads over Europe, where detailed information on its biology is limited. • The thermal requirements for the development and life history of L. occidentalis were examined in Slovakia, and the number of potential generations was estimated across Europe. • The outcomes of this study provide important data for evaluating management options of this species.

“…These three species are widespread and abundant in southern Europe. Originally North American, L. occidentalis is of particular interest, as it has demonstrated enormous ecological adaptability by establishing on available habitats across the entire European continent within a decade [42][43][44] after its original detection in Italy in 1999 [45,46]. In most countries, rapid spread and increasing population density were observed shortly after detection.…”

“…Among the sucking insects, Aradus cinnamomeus (Panzer, 1806) (Hemiptera: Aradidae) has local importance in some regions of the Northeast zone, while the invasive L. occidentalis is widespread in suitable habitats across the region-including southern Poland [43], Ukraine, and Russia [186]-and has been locally expanding its range over the recent years [187]. This species actively flies from one pine to another to feed and breed, and during these activities, it can act as a vector for fungi.…”

Pine Pitch Canker and Insects: Regional Risks, Environmental Regulation, and Practical Management Options

Pine pitch canker (PPC), caused by the pathogenic fungus Fusarium circinatum (Nirenberg and O' Donnell), is a serious threat to pine forests globally. The recent introduction of the pathogen 2 of 34 to Southern Europe and its spread in Mediterranean region is alarming considering the immense ecological and economic importance of pines in the region. Pines in forests and nurseries can be infected, resulting in severe growth losses and mortality. The pathogen is known to spread in plants for planting and in seeds, and results from recent studies have indicated that F. circinatum may also spread through phoretic associations with certain insects. With this review, we aim to expand the current understanding of the risk of insect-mediated spread of PPC in different parts of Europe. Through the joint action of a multinational researcher team, we collate the existing information about the insect species spectrum in different biogeographic conditions and scrutinize the potential of these insects to transmit F. circinatum spores in forests and nurseries. We also discuss the impact of environmental factors and forest management in this context. We present evidence for the existence of a high diversity of insects with potential to weaken pines and disseminate PPC in Europe, including several common beetle species. In many parts of Europe, temperatures are projected to rise, which may promote the activity of several insect species, supporting multivoltinism and thus, further amplifying the risk of insect-mediated dissemination of PPC. Integrated pest management (IPM) solutions that comply with forest management practices need to be developed to reduce this risk. We recommend careful monitoring of insect populations as the basis for successful IPM. Improved understanding of environmental control of the interaction between insects, the pathogen, and host trees is needed in order to support development of bio-rational strategies to safeguard European pine trees and forests against F. circinatum in future.

Alien True Bugs of Europe (Insecta: Hemiptera: Heteroptera)

This paper reviews the alien (non-native, non-indigenous, exotic) true bug (Heteroptera) species in Europe. Forty-two established alien Heteroptera are recognized, of which 12 species are alien to Europe (originating outside Europe: eight from North America, three from the Eastern Palaearctic, one from New Zealand), 24 species are alien within Europe (translocated within Europe), and six cryptogenic species are of unknown origin. Since 1990 an approximate arrival rate of 7 species per decade has been observed. A recent trend of increased introductions from North America to Europe is suggested. The most important pathway of alien Heteroptera is translocation as contaminants (49 %), usually with ornamental plants, followed by unintentional introduction through natural dispersal (unaided) across political borders within Europe (28 %), and translocation as stowaways within a transport vector (21 %). The taxonomic composition of the alien Heteroptera of Europe is dominated by Miridae (17 species, 40 %), Tingidae (8 species, 19 %), and Anthocoridae (5 species, 12 %), all of which are overrepresented compared to the native European Heteroptera fauna. More than half of the species are phytophagous (24 species, 57 %) and the advantage of trophic specialization in invasion success is discussed. Most species are currently known to occur in the Czech Republic (19 species) and Germany (17 species), followed by Western European countries (Belgium 15 sp., France and United Kingdom 14 sp. each, and Netherlands 13 sp.), resulting in an apparent (north)west–(south)east gradient probably reflecting horticultural tradition in Europe. No unambiguousevidence exists so far for negative ecological or economical impacts, but more research is needed to investigate possible effects. Introductions of alien Heteroptera to and within Europe will increase, and deserve further consideration.
