Lycorma delicatula(Hemiptera: Auchenorrhyncha: Fulgoridae: Aphaeninae) finally, but suddenly arrived in Korea

Abstract

A history of name changes in two fulgorid species –Lycorma delicatula and Limois emelianovi– is reviewed. Lycorma delicatula was once mistakenly reported to occur in Korea. Now, it has suddenly become common in western Korea, creating the suspicion that it has recently arrived from China and settled in Korea. A brief morphological and biological description of L. delicatula is provided, and its original Korean name, “ggot‐mae‐mi”, is revalidated. Limois emelianovi, sometimes considered a synonym of emeljanovi, is the correct name for this species, as emeljanovi is simply another transliteration of the personal name Emelianov, Emeljanov or Emel’yanov. The name emelianovi stands correct based on the International Code of Zoological Nomenclature code 32.5.1, because there is no internal evidence of an inadvertent error, and an incorrect transliteration is not considered an inadvertent error. The cytochrome oxidase I (COI) barcoding regions of both species were sequenced and compared for future reference.

Development and characterization of 15 microsatellite loci fromLycorma delicatula(Hemiptera: Fulgoridae)

“…In an earlier study, Korean and Chinese populations of L. delicatula could not be discriminated using the COI barcode region, in which their sequences were identical (Han et al 2008). Moreover, we found no difference between sequences of two internal transcript spacers (ITS1, ITS2) in our preliminary tests (unpublished data).…”

“…A better understanding of its population genetic structures is also important for effective control. Conventional molecular markers such as the mitochondrial COI barcode do not seem relevant to resolving the L. delicatula populations rapidly dispersing in Korea (Han et al 2008). Hence, to provide a tool for studying such factors as source of invasion, dispersal, and population genetics, we here report 15 polymorphic microsatellite loci.…”

“…Lycorma delicatula has recently been introduced into Korea, where it has become a serious pest of grapes (Han et al 2008;Lee et al 2011). This species arrived suddenly in the country, where it now seriously damages grapevines and brings more economic losses each year (Han et al 2008;Shin et al 2010).…”

“…Although the authenticity of previous Korean records of this species has been controversial, it now appears that the historical confusion derived from Doi's misidentification of another fulgorid, Limois emelianovi (Doi 1932a, b;Han et al 2008). Continuing outbreaks of L. delicatula over the past several years also corroborate the argument that L. delicatula has not been present in Korea until the 2000s (Han et al 2008). It obviously corresponds to the invasion history of other exotic insects such as the pine needle gall midge, Thecodiplosis japonensis, and the yellow locust midge, Obolodiplosis robiniae, both of which increased explosively immediately after their introductions into Korea (Jung et al 1997;Woo et al 2003).…”
