All of them were susceptible. Lower root-lesion indices and fewer number of nematodes per gram of roots occurred on Singapore, Solomon Islands-2, Solomon Islands-3, Hirehalli, Thirthahalli oval, local varieties of Areca catechu, and Saigon variety of A. calapparia, than on other varieties tested. The varieties Mangaia, Mahuva-B. and Cruckmagalore of A. catechu and A. macrocalyx variety New Ireland exhibited higher infection rates and root-lesion indices. Maximum root-lesion indices and moderate nematode infection occurred on A. catechu variety Assam and A. triandra variety Indonesia-I. A. calapparia. A. langlpsiana. A. macrocalyx, A. nor-manbyii and A. triandra are reported as new hosts for R. similis.enArticle
