Abstract


The sapodilla (Manilkara zapota van Royen), also known as naseberry, nispero, zapote, zapotillo, chicozapote, native to Mexico and Central America is currently grown in southern Florida. Pests and diseases are not usually considered a major problem on sapodilla; however, the larva of the small moth Banisia myrsusalis has been reported as an occasional pest that causes extensive damage to sapodilla blooms in Florida. Damage to buds, flower drop, and damage to 70% of fruits have been observed (Peña, unpublished data). A preliminary survey of sapodilla groves was conducted from May to July 2002, since very little was known about this moth. The survey indicated the presence of lepidopterous pests feeding on the young leaves, flowers, or young fruits. Three Lepidoptera species were frequently encountered: Banisia myrsusalis (Lepidoptera: Thyrididae), Dichrorampha sapodilla (Lepdioptera: Tortricidae), and a Zamagiria sp. (Lepidoptera: Pyralidae). A test was conducted in 2006 to determine the efficacy of Fury, Novaluron, Venom, Danitol, Thiamethoxan, and Alverde for control of the sapodilla moths.
