Abstract

Damages of medicinal crops by thrips and identification of thrips species were investigated by periodic surveys on major medicinal crops, Platycodon grandiflorum, Schizandra chinensis, Codonopsis lanceolata, Lycium chinense, Bupleurum falcatum, Ledebouriella seseloides, Angelica gigas, Glycyrrhiza uralensis, Liriope platyphylla, Atractyloides sp., once or twice a month in Suwon, Eumseong, Jecheon, Pyeongchang, Chyungyang from May to October in 2012. Thrips and their damages were found at all of the medicinal crops investigated, mostly occurring at early growing stages of each medicinal crop and causing apical meristem region withered, thereby inhibiting the growth of plants. For species identification of thrips collected from each medicinal crops, DNA from each individual was extracted and ITS2 and COI regions were amplified by PCR. As a result, Frankliniella intonsa, Thrips tabaci, and Megalurothrips distalis have been identified as dominant species on medicinal crops in open field, whereas Frankliniella occidentalis was restricted to Lycium chinense in which protected cultivation. This study suggests that the occurrence of thrips species on medicinal crops seems to be affected by host specificity and environmental factors such as cultivation types.
