薩南諸島の主としてサトウキビ畑の植物寄生性線虫

抄録

Plant-parasitic nematodes in soil were surveyed covering 97 sugar-cane fields and other 36 cropones in the Satsunan Islands, including Tanegashima, Yakushima, Kikaigashima, Tokunoshima, Okino'erabujima and Yoronto, where annual mean temperature was 20°C or so.
The genera found and their distribution were shown in table 1, and the species discussed were listed in the text with short morphological notes, if necessary.
Of the 17 genera investigated, the following S genera of Helicotylenchus, Pratylenchus, Tylenchorhynchus, Meloidogyne and Rotylenchulus appeared frequently. Some main species of these genera were tabulated in table 4 with their distribution in this region. The genus Tylenchorhynchus is striking for its wide distribution and Tylenchorhynchus sp. 2 is considered as a species in warmer regions.
