云南水稻潜根线虫种类的初步研究

PRELIMINARY STUDY ON SPECIES OF HIRSCHMANNIELLA IN YUNNAN CHINA

研究鉴定出云南省水稻潜根线虫10种:贝氏潜根线虫(Hirschmanniellabelli)、刻尾潜根线虫(H.caudacrena)、分离潜根线虫(H.diversa)、纤细潜根线虫(H.gracilis)、伊玛姆潜根线虫(H.imamuri)、墨西哥潜根线虫(H.mexicana)、小结潜根线虫(H.microtyla)、尖细潜根线虫(H.mucronata)、水稻潜根线虫(H.oryzae)、刺尾潜根线虫(H.spinicaudata)。水稻潜根线虫、伊玛姆潜根线虫为优势种。田间组合总趋势为水稻潜根线虫和伊玛姆潜根线虫。

Rice root nematode (Hirschmanniella spp.), parasitizing the root of rice and other water plants, is a widespread and very harmful pest. In the study reported in the present paper, 10 species of this genus were identified in Yunnan Province: H. belli Sher, 1968; H. caudacrena Sher, 1968; H. diversa Sher, 1968, H. gracilis (de Man, 1880) Luc et Goody, 1964; H. imamuri Sher, 1968; H. mexicana (Chitwood, 1951) Sher, 1968; H. microtyla Sher, 1968; H. mucronata (Das, 1960) Luc et Goody, 1964; H. oryzae (van Breda de Haan, 1902) Luc et Goody, 1964; and H. spinicaudata (Schuurmans Stekhoven, 1944) Luc et Goody, 1963. H. oryzae and H. imamuri are the dominant species, and they represent the trend of species combination in paddy fields.
