Abstract
Two biotypes of Tylenchulus semipenetrans Cobb obtained in Italy from olive (Olea europaea L.) and Citrus sp. (Inserra and Vovlas, 1978) were classified as the «Citrus biotype» and the «Mediterranean biotype» respectively (Inserra et al., 1980) The « Mediterranean biotype» reproduces on Citrus spp., and 'Troyer' Citrange [CO sinensis Osb. x Poncirus trifoliata (L.) Raf.], but not on citrumelo (C. paradisi Macf. x P. trifoliata), P. trifoliata selections or olive (Lamberti et al., 1976). This note reports the reaction of several citrus and noncitrus rootstocks to a Sicilian populations of T. semipenetrans.
