The potato tuber moth, Phthorimaea operculella (Zeller) is one of the most destructive pest of potatoes. Also, we found this species attacking the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae). Ratio of para- sitism is 20-30% and cocoon of lepidopteran was parasitic ichneumonid species after 3 days. This species and the genus Diadegma are recorded for the first time from Korea. In this paper, description of the parasitoid and photographs of the diagnostic characteristics are provided. Keywords: Diadegma fenestrale, Ichneumonidae, parasitoid, Phthorimaea operculella, Korea INTRODUCTION moth, Phthorimaea operculella (Zeller) is one of the most destructive pest of potatoes (Rondon, 2010). The subfamily Campopleginae, was first described by Förster In this study, we found a newly recorded species, Diadeg- in 1869 based on the genus Campoplex. Members of this ma fenestrale (Holmgren, 1860) attacking the potato tuber subfamily include 2,133 species in 70 genera from around moth, Phthorimaea operculella (Zeller) in Korea. the world. Among them, 489 species are distributed in the The materials used in this study were collected from Jeju, Eastern Palaearctic region, and 23 species have been recorded Korea in 2009. The wasps were reared on Phthorimaea oper- in Korea (Yu et al., 2005). Yu et al. (2005) listed 23 species culella in plastic cages under conditions of 25±2�C, 16L : belonging to the subfamily Campopleginae from Korea, and 8D photoperiod, and 50-70% relative humidity. Lee and Choi (2007) and Choi and Lee (2008a, 2008b, 2010a, Specimens were picked from newly emerging females out 2010b), and Choi et al. (2011, 2012) added 14 species. In of a mass rearing cage and examined by stereo microscopy this study, we confirmed 38 Korean species in 15 genera. (Zeiss Stemi SV 11 Apo; Carl Zeiss, Göttingen, Germany).
