The western conifer seed bug, Leptoglossus occidentalis Heidemann, and the southern pine seed bug, L. corculus (Say), feed on the developing seeds of conifers causing great losses to seed crops (Koerber 1963; Connelly and Schowalter 1991; Schowalter 1996). When high populations threaten the yieldof genetically superior, high quality seed in seed orchards, chemical controls may be used (DeBarr et al. 1982). However, because even minor uses of chemical pesticides are increasingly restricted, particularly in British Columbia where seed orchards commonly interface with urban areas, damaging populations of L. occidentalis may not be controlled at all.

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).

Data on the first registration of conifer seed bug Leptoglossus occidentalis in Armenia are presented. Penetration of the species from Georgia due to self-dependent expansion or unintentional delivery is presumed.

The Nearctic coreid Leptoglossus occidentalis Heidemann 1910 (Hemiptera: Coreidae) known as the Western Conifer Seed Bug, is recorded for the first time in Greece. This highly dispersible species is well established in Europe and was collected by the authors in various areas of continental Greece (Central Evia, Attica and North Peloponnisos), suggesting a wide distribution in this country.

Abstract Leptoglossus occidentalis (Heidemann) is an invasive species introduced in Europe, Asia, and most recently South America. In the present study, we report the overreaction situation caused by this bug in Chile, as it has been confused with kissing bugs (Reduviidae: Triatominae), Chagas’ disease vectors. During 2018 and first months of 2019, we received 74 alleged cases of kissing bugs to confirm identification. From these, a total of 63 were identified as L. occidentalis, representing a 85% of the total denounces. Additionally, the first bite case in a human is described. The situation caused by L. occidentalis in Chile is discussed, and an illustrated table is provided to correctly identify this species and tell it apart from Triatomines. It is concluded that L. occidentalis is well established in Chile, and it is necessary to educate the population on recognition of the bug and to avoid overreaction as the species can inflict painful bites, but not transmit any disease.

Compliance with agronomic regulations in farms that ensure high quality seeds (conducting grade and species weeds on seed crops, compliance with harvesting, part-time, seed storage, etc.) must be constantly monitored in order to improve production on the way to the cultivation of high-quality seed material.
