Plants in large areas of poor growth were colonised by R. nativus , whereas in areas of better growth Pratylenchus neglectus occurred at lower population densities. The boundary between the areas was distinct. In the

Paratylenchus species ( P. microdorus , P. similis , P. nanus and P. ciccaronei ) were the most abundant and prevalent plant-parasitic nematodes found. Pratylenchus neglectus and P. thornei were widely distributed in 55
