It is also called Tea root-knot nematode, Mature tea nematode or Indian root-knot nematode. It is a member of the root-knot nematodes, which was identified by C. A. Loos in 1953 in Sri Lanka.〔Loos, C. A. 1953. Meloidogyne brevicauda, n. sp. a cause of root-knot of mature tea in Ceylon. Proceedings of the Helminthological Society of Washington 20:83-91.〕 == Description == Female ''M. brevicauda'' has a narrow procorpus, a large metacorpus, a large glandular region that has one dorsal and two subventral esophageal gland lobes. Two large nucleated esophago-intestinal cells are at the dorsal base of the metacorpus junction with the intestine. The labial disc and lips are prominent and protrude from the regular body contour. The perineal pattern appears with high squared dorsal and ventral arches without prominent lateral lines.〔Eisenback, J. D.; Gnanapragasam, N. C.1992. Additional notes on the morphology of Meloidogyne brevicauda. Fundamental and Applied Nematology Vol. 15 No. 4 pp. 347-353〕 Male ''M. brevicauda ''has a slit-like stoma surrounded by six small, pore-like openings of the inner labial sensilla. The head annulations are absent. The lips are set off from the body annulations because the diameter of the lips is larger than that of the first body annule. The first body annule is also narrower than the remaining body annules. The shape of the head of males of ''M. brevicauda'' is very different from that of most root-knot males. The labial disc of most males of ''Meloidogyne'' is fused with the medial lips, but in ''M. brevicauda'',the labial disc is distantly separated from them by a deep groove. Other than that, most root-knot males have a large head annule that may be further divided by irregular or incomplete annulations. Males of ''M.brevicauda'' do not have a head region, the lips are immediately adjacent to the first body annule. The tail is marked by acrescent-shaped fold in the cuticle surrounding the posterior portion of the cloacal opening.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Meloidogyne brevicauda」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
