Presence of Aphelenchoides cocophilus in the Roots of Cocos nucifera, the Coconut Palm

Abstract

LITERATURE on red ring disease of coconuts, caused by the nematode, Aphelenchoides cocophilus 1,2, leaves the reader in doubt regarding the primary site of infection. Nowell3 referred to the disease in Grenada as ‘root disease’ and considered the roots to be the primary site of infection. Later4, he changed his opinion and regarded root infections as secondary to stem. Other workers5,6 suggested that the disease was transmitted by the palm weevil, Rhyncophorus palmarum (L.). One of us7 advanced the view that the disease frequently started in the base of the tree and suggested that infection might occur via the roots.
