A survey was conducted to identify and quantify the frequency and population density of plant parasitic nematodes genera associated with tomato in Ethiopia, during 2018 cropping season. A total of one hundred nineteen composite soil and root samples were randomly collected from tomato growing areas of Oromia, SNNP, Tigray and Amhara regions. A total of eight plant parasitic genera were detected in the surveyed regions, viz Meloidogyne, Helicotylenchus, Pratylenchus, Criconema, Rotylenchulus, Scutellonema, Paralongidorus and Hoplolaimus. Meloidogyne was the most abundant and frequent genus with 283 nematodes/10g root and 45% frequency occurrence respectively. Helicotylenchus was second most frequent genus with (36%) frequency of occurrence. But in terms of abundance Pratylenchus was the second most abundant genus with mean population density of 73 nematodes/10g root followed by Helicotylenchus (62 nematodes/100ml soil). Of all the genera detected the least frequency of occurrence of (2%) and (3%) were observed with genera Criconema and Paralongidorus respectively. Additionally, Criconema and Paralongidorus were observed with lowest equal mean population density of 20 nematodes/100ml. The aim of the study was to know the distribution of plant parasitic nematodes across the four regions. Among the surveyed four regions Oromia was positive for all of the eight detected plant parasitic nematode genera while SNNP for five genera and Amhara and Tigray were positive for four and two nematode genera respectively. Criconema and Rotylenchulus were only detected in Oromia region. Moreover, the agro-ecological difference present in the sampling sites might be the underlying causes for the variation of nematode prevalence, abundance and diversity across the four regions. The study encourages more research work on establishing economic importance and designing management strategies on reported nematode pests.
