Pratylenchus goodeyi is considered native to Africa. It is widely distributed on banana in the Canary Islands and East Africa.
Ecological ranges of Radopholus similis and Pratylenchus goodeyi differ in sub-Saharan Africa. R. similis appears to be a recent introduction to Africa and is restricted to lower altitudes. In the cooking and dessert banana regions around Lake Victoria in East Africa (Kenya, Uganda, Tanzania), Pratylenchus goodeyi is the predominant migratory endoparasite of bananas at altitudes above 1000 m. That area produces about 25% of the world's bananas and plantains, mainly for domestic use.
Banana.
Males common.
Similar damage to Radopholus similis in banana. Lesions, cavities, root destruction.
Most serious root pest of cooking banana in Tanzania; occurred on 94% of farms sampled and caused toppling or yield loss on 85% of farms.
Similar management strategies are proposed as for R similis. However, in many cases those practices are not economically feasible as production is generally on small subsistence farms with no economic base.
