“…Its life history is well studied in North America (Koerber 1963;McPherson et al 1990; Bates and Borden 2005), and some data on phenology and biology have been presented from southern Europe (Bernardinelli et al 2006;Maltese et al 2009;Tamburini et al 2012;Mas et al 2013). While WCSB is univoltine in North America, several generations can be developed annually in Mexico (Koerber 1963;Mitchell 2000). Recently, one to three generations per year have been observed/predicted in Spain and Italy (Bernardinelli et al 2006;Maltese et al 2009;Tamburini et al 2012;Mas 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.

Pine nuts are non-wood forest products (NWFP) with a constantly growing market notwithstanding a series of phytosanitary issues and related trade problems. The aim of this paper is to review the literature on the relationship between phytosanitary problems and trade development. Production and trade of pine nuts in Mediterranean Europe have been negatively affected by the spreading of Diplodia sapinea (a fungus) associated with an adventive insect Leptoglossus occidentalis (fungal vector), with impacts on forest management, production and profitability and thus in value chain organization. Reduced availability of domestic production in markets with a growing demand has stimulated the import of pine nuts. China has become a leading exporter of pine nuts, but its export is affected by a symptom caused by the nuts of some pine species: 'pine nut syndrome' (PNS). Most of the studies mentioned in the literature review concern PNS occurrence associated with the nuts of Pinus armandii. We highlight the need for a comprehensive and interdisciplinary approach to the analysis of the pine nuts value chain organization, where research on food properties and clinical toxicology may be connected to breeding and forest management, forest pathology and entomology, and trade development.

“…Both adults and nymphs feed by inserting their stylets into cones and digesting the contents of developing seeds, and they can cause serious economic losses in high-value seed orchards (Strong et al 2001;Bates et al 2002;Bates and Borden 2005). In late summer and early fall, L. occidentalis adults seek sheltered locations in which to aggregate and overwinter, including tree cavities, animal nests, and manmade structures (Hussey 1953;Koerber 1963;Gall 1992;Blatt 1994). Aggregations appear to be mediated by a male-produced pheromone (Blatt and Borden 1996) and may contain a few to over 2000 individuals (Blatt 1994).…”

The western conifer seed bug, Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae), is a polyphagous pest of coniferous trees (Hedlin et al. 1981). Native to western North America, the seed bug has expanded its range to include eastern Canada and the United States (McPherson et al. 1990; Gall 1992; Marshall 1992; Ridge-O'Connor 2001; Bates 2002) and was recently introduced into Europe (Taylor et al. 2001). Both adults and nymphs feed by inserting their stylets into cones and digesting the contents of developing seeds, and they can cause serious economic losses in high-value seed orchards (Strong et al. 2001; Bates et al. 2002; Bates and Borden 2005).
