First detection of the cosmopolitan invader Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) in Argentina

Abstract

Leptoglossus occidentalis Heidemann is a conifer seed bug, native to North America. This species is considered invasive and has reached several countries in the Northern Hemisphere and most recently Chile in South America. This work reports the first detection of this species in Argentina, with specimens from the Rio Negro province, in 2017. ecological traits and its potential rapid spread were also discussed.

Responses of native egg parasitoids to the invasive seed bug Leptoglossus occidentalis

“…Within just a decade, it was found from Norway to Sicily and from Portugal to South of Russia (Fent & Kment, 2011;Gapon, 2012). Moreover, WCSB has become a highly successful worldwide invader with observations in Asia (China; Zhu (2010), Japan; Ishikawa and Kikuhara (2009) and South Korea; Ahn et al (2013)) but also in North Africa (Morocco; Gapon (2015), Tunisia;Ben Jamaa et al (2013)) and South America (Chile; Faúndez and Rocca (2017), Argentina; Kun and Masciocchi (2019) and Uruguay (Faúndez & Silvera, 2019)). Recent observations suggest that WCSB has spread to South Africa and Brazil (van der Heyden & Faúndez, 2020).…”

First records of the invasive species Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae) on different coniferous species including the cedars of Lebanon

“…In 1992, it was reported in Pennsylvania after a period of silence and its range started to extend around the world (van der Heyden 2019a). (van der Heyden 2017(van der Heyden , 2018b(van der Heyden , 2018c(van der Heyden , 2019a(van der Heyden , 2019b(van der Heyden , 2019dKun and Masciocchi 2019). It was found near Lebanon in 2016 in eastern Turkey (Özgen et al 2017) and has been recently reported in the northern part of the Golan Heights (van der Heyden 2018a) and in the western Galilee (van der Heyden 2019c).…”

Native egg parasitoids on Leptoglossus occidentalis Heidemann (Hemiptera: Coreidae) in Spain: Potential biological control agents?

“…more than 40 conifer species) (Fent & Kment, 2011) and anthropogenic activities (Kim et al., 2020). The latest records show that the WCSB continues to move across Central and South America, Africa (Faúndez et al., 2017; Faúndez & Silvera, 2019; Kun & Masciocchi, 2019; Van der Heyden & Faúndez, 2020), Europe (Lesieur et al., 2019) and Asia (Kim et al., 2020). The phenology of the WCSB depends on environmental conditions (Barta, 2016; Tamburini et al., 2012) and is characterized by overwintering in large aggregations in sheltered locations (Blatt, 1994).…”
