Abstract

In surveys of pineapple [Ananas comosus (L.) Merr.] fields at Kawanda Research Station and in those of the Masaka Cooperative Union at Masaka, Uganda, 12 genera of plant parasitic nematodes were found. Helicotylenchus Steiner was the most frequently encountered; it was found in 88.6 and 90.0 percent of the 70 and ten soil samples from Kawanda and Masaka respectively. It was also the most numerous at both sites. Pratylenchus brachyurus (Godfrey) Goodey and Meloidogyne Goeldi were the predominant endoparasitic nematodes encountered at both sites. Also common and numerous at Kawanda were Rotylenchulus reniformis Lindford & Oliveira and species of Scutellonema Andrassy and Tylenchus Bastian. Nematode population densities were correlated with rainfall and past agroecosystems.
