Inoculation was effected by inserting fragments of diseases tissue or a water suspension of the nematode into holes made in the tree at the sites mentioned above. Nematodes also penetrated intact tissue of leaf axils, petioles and roots. External symptoms appeared 40-70 days after inoculation and trees were dead in six to eight weeks after symptoms first appeared. The coconut does not become naturally infested but green nuts were successfully infested artificially both on trees and in the laboratory. The epicarp of infested nuts became brown, hard and shrivelled. The mesocarp became reddish brown and containedliving nematodes. The nematodes did not pass from infested to healthy nuts through the fruit stalk. R. cocophilus is found intercellularly and intracellularly in the ground parenchyma of infested tissue. Some cells disintegrate forming cavities in which nematodes are abundant. Many of the cells in the infested tissue lose their contents. The nematodes tend to migrate to areas with living cells. Adults and eggs are in greater numbers in the crown region of trees where lesions terminate in elongate streaks and dots of orange colored tissue.
