First Record of the Western Conifer Seed Bug, Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) in Korea

Abstract

Leptoglossus occidentalis Heidemann, 1910 was newly recorded in Korea as a invasive species at Gyeongsangnam-do, Korea in 2010 and 2011. Leptoglossus Guérin-Méneville, 1831 is also newly recorded Coreid genus in Korea. The diagnostic shape is expanded leaf-like hind tibiae. The origin of this species is North America and it has been rapidly propagated around the world as a pest. This bug recognized as a pest on almost of Pinaceae plants and they suck on developing cones, so the monitoring on the present invasion of this species in Korea is urgent. It was presumed that the invasion of Leptoglossus occidentalis into Korea was before 2010 with present study.
