Host plants: Odoniella reuteri and O. rubra have been recorded from cocoa ( Leston, 1970; Entwistle, 1977). Odoniella apicalis and O. rubra are also known from Piper spp. (Piperaceae) , Odoniella camerunesis was recorded from Culcasia parviflora (Araceae) , and Odoniella similis is known from Smilax sp. (Smilaceae) ( Odhiambo, 1962; Hill, 1983).
