In Peru, the pineapple (Ananas comosus var. comosus) has 14 000 cultivated hectares, with an average yield of 22 t/ha. Commercial cultivars in order of importance are’Samba’,’Hawaiana’,’Pucalpina’,’Roja Trujillana’,’Cayena Lisa’ and ‘Golden’ (MD-2) which are cultivated in different regions of the country, but the largest areas are in the central jungle. The pineapple has several phy-tosanitary problems, but the most important is the “fruit spot” caused by Penicillium funiculosum and Fusarium moniliforme. There are three types of spots: “dry black spot”, “wet black spot” and “spot with galleries”, the latter being the most important and associated with the “pineapple fly” (Melanoloma viatrix). This paper presents a review of the biology of the “pineapple fly”, a description of the “spot with galleries” and the experiences developed for its control in the country.
