Identification of mealybugs of the genus Planococcus (Homoptera: Pseudococcidae) occurring on cacao throughout the world.
A key to the species of Planococcus that occur on cocoa is presented. P. celtis and P. lamabokensis are transferred to Planococcoides. Planococcus pacificus is shown to occur commonly on cocoa in the Neotropical Region as well as in the Australo-Oriental and Polynesian Regions, suggesting that many records of P. citri from the Neotropics refer to this species. Characters for separating these two species are given.
