In this paper 402 publications are listed in the Bibliography of Plant Nematodes of the American Tropics, and 57 other publications which, in some respect, refer to the subject, making a total of 459. These publications cover the following countries in the American Tropics, in which actual research on plant nematodes has been or is being pursued: Hawaii, Brazil, Peru, Puerto Rico and certain islands of the Caribbean, Bolivia, Columbia, Ecuador, Venezuela, Panama, Guatemala, Costa Rica, El Salvador, Honduras, and Mexico. In spite of the fact that a relatively large number of countries have conducted research on plant nematodes, only a restricted number of crops are covered, such as pineapple, banana, sugarcane, coffee, coconut palm, cotton, kenaf, potato, and certain vegetables.
