英语. The occurrence of Meloidogyne in several areas of Macedonia was surveyed. Seventy-three isolates from nine locations (fields and glasshouses) were identified and their behaviour on two susceptible and two Mi resistant tomato cultivars compared. M. incognita (47.9%) and M. javanica (35.6%) are the predominant species, followed by M. arenaria (13.71%) and, sporadically, M. hapla (2.7%) was found. Mixtures of species were present at nearly all locations. Virulent isolates were found in M. incognita (11%) and M. javanica (46%) as well as in M. arenaria (50%). M. hapla isolates were compatible with all tomato genotypes tested. The impact of the occurrence of virulence for Mi carrying tomato genotypes is discussed

Sono stati identificati 73 isolati derivanti da nove localita' (in campo e in serra) ed e' stato confrontato il loro comportamento su due varieta' suscettibili e su due varieta' Mi resistenti di pomodoro. M. incognita (47,9%) e M. javanica (35,6%) sono le specie predominanti, seguite da M. arenaria (13,71%); sporadicamente e' stata rinvenuta M. hapla (2,7%). Mescolanze di specie erano presenti in quasi tutte le localita'. Sono stati trovati isolati virulenti in M. incognita (11%) e M. javanica (46%), come in M. arenaria (50%). Gli isolati di M. hapla erano compatibili con tutti i genotipi di pomodoro saggiati. Viene discusso l'impatto della presenza di virulenza per genotipi di pomodoro dotati del gene Mi]
