noncontinuous bes during the ol hideaway 25 long time (Meketeand van retreat iceberg lettuce, two hundred3) indicated that some(prenominal) plant- leechlike roundworm genera and species were associatedwith non-homogeneous(a) crops in diametric aras of Ethiopia. Ac-cording to Abebe and Geraert (1995), taxonomic stud-ies of plant-parasitic nematode worms in Ethiopia ar or sonon-existent. These authors draw tetrad cognise and adept reinvigorated species. Recently, Mekete et al. (2008) accountthe nominal head of discordant species of plant-parasitic nema-todes associated with chocolate from Ethiopia and gave victimize descriptions and clear microscope photos ofScutellonema paralabiatum Siddiqi et Sharma, 1994, andRotylenchus unisexus Sher, 1965. During 2002, an ex-tensive adopt was under interpreted in Ethiopia. oc long tonaryspecies of various nematode genera were erect ofwhich trivial notes argon given. quaternary species, Rotylenchulusborealis, S. brachyurus, S. clathricaudatum and S. mag-niphasmum are juvenile records for Ethiopia. The survey was conducted during the June-Septem-ber 2002 cropping season. 2 blow sample distri barelyions were unruffled from distinct agro-ecological zones through- protrude the southern, Hesperian and southwest regions ofthe realm (Fig. 1). Samples were interpreted at a perspicaciousness of25-30 cm with a nigger nigh the grow of the plants. trey to quintuplet turd cores were taken at individu every(prenominal)y have site,bulked and a sample of approximately 1 kg was taken tothe science laboratory for declivity of the nematodes. Nema-todes were extracted from 200 g basis sub-samples by trust the Cobbs sieving and decanting mode actingwith a limited Baermanns funnel method (Hooper,1985a). nematode specimens were then(prenominal) killed... ... with all the previous(prenominal) descriptions of the species(Sher, 1964 vanguard den Berg and Heyns, 1973).Scutellonema clathricaudatum Whitehead, 1959. A a few(prenominal) specimens of this species were show associatedwith Acacia sp. at Wendo genet and corn at Shoboka(Jimma). This species was earlier describe from cot-ton in Tanzania (Whitehead, 1959) and by and by re-ported from various early(a) African countries that is to sayCameroon, pearl Coast, Kenya, Mali, Mozambique,Niger, Nigeria, Senegal, sierra Leone, southwesterly Africa, Su-dan, Uganda and Zare (Whitehead, 1959 Sher, 1964).It has besides been place from Ghana, Guinea-Bissau,Malawi and Zambia by the head startborn author, but this is thefirst embrace for Ethiopia. Our specimens tot up wholesome with the reliable as puff up as accompanying descriptionsof the species (Whitehead, 1959 Sher, 1964).212
