“…Its fast spread obviously demonstrates a great invasive potential. The high spreading capacity is also supported by recent findings of WCSB in North Africa, Tunisia (Jamâa et al 2013) and East Asia, Japan (Ishikawa and Kikuhara 2009), north-eastern China (Zhu 2010), and Korea (Ahn et al 2013). Several independent introduction events of WCSB population are suspected in Europe.…”

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.

“…It was then observed to colonize the whole European continent in less than 15 years (Dusoulier et al 2007;Fent and Kment 2011;Gapon 2012;Malumphy et al 2008). Moreover, recent observations in Eastern Asia (Ahn et al 2013;Ishikawa and Kikuhara 2009;Zhu 2010), northern Africa (Ben Jamaa et al 2013;Gapon 2015), Asia Minor (Van der Heyden 2018) and South America (Faúndez and Rocca 2017) confirmed that L. occidentalis has become a highly successful worldwide invader.…”

The rapid spread of Leptoglossus occidentalis in Europe: a bridgehead invasion

et al. 2018

Retracing the routes of invasions and determining the origins of invading species is often critical in understanding biological invasions. The Western conifer seed bug, Leptoglossus occidentalis, an insect native of western North America, was first accidentally introduced to eastern North America and then to Europe. The colonization of the entire European continent occurred in ca. 10-15 years, probably promoted by independent introductions in different parts of Europe. A multi-marker approach (mtDNA and microsatellites) combined with approximate Bayesian computation analyses was used to track the origin of European populations and to determine whether this rapid invasion was caused by multiple introductions. Our results show that at least two independent introductions of L. occidentalis have occurred in Europe. Moreover, the analyses showed a stronger genetic similarity of European invasive populations with the eastern North American populations than with those of the native range, suggesting that invasive North American population acted as a bridgehead for European invasion. The results also revealed that natural dispersal as well as human-mediated transportations as hitchhikers probably enhanced the rapid spread of this invasive pest across Europe. This study illustrates the complexity of a rapid invasion and confirms that bridgehead and multiple introductions have serious implications for the success of invasion.

“…Vast geographic range expansion has occurred through commercial movement of plants. For example, the coniferfeeding Leptoglossus occidentalis Heidemann, formerly restricted to western North America, spread eastward as far as Ontario and Connecticut and then, following accidental introductions, has spread through most of Europe, most recently being reported from Turkey (Hizal 2012 ) and parts of Asia, most recently Korea (Ahn et al 2013 ). The Neotropical Leptoglossus zonatus (Dallas), long known as a highly polyphagous crop pest in Central and South America and Mexico, has also expanded its range recently, moving across the southern United States from Texas to Florida, becoming a problem in satsuma oranges and other citrus (Xiao and Fadamiro 2010 ).…”

The family Coreidae is distributed worldwide, but these phytophagous bugs are most abundant in the tropics and subtropics. In the Neotropical region, all of the subfamilies and 16 tribes are represented. In tropical ecosystems, these bugs feed on herbs and shrubs in open areas of forests as well as at the forest edge. Some species are spectacularly colored, and unusual expansions of antennae, humeral angles, femora, or tibiae occur in many groups. Some of them move lazily even when disturbed and hardly fl y to escape; others are extremely nimble, fast fl ying away when disturbed. They are frequently encountered in crops, representing important pests in several commodities. No one common name is universally accepted for the family, and none of the frequently used names (e.g., squash bug, leatherbug, leaf-footed bug, Randwanzen) are collectively appropriate for all members of the family.
