Conteúdo: 	Resistance of citrus fruit to attack by the Caribbean fruit fly, Anastrepha suspensa (Loew), was attributed to allelopathic essential oils in the flavedo region of the peel. Hatchability of eggs laid between peel oil glands was significantly greater than that of eggs laid into glands. Mortality occurred principally in the 1st larval instar, and most larvae died before reaching the albedo. Grapefruit were more susceptible to larval development than oranges, and lemons were virtually immune to successful attack by this fly. Fruit that were allowed to remain on the tree until overripe were somewhat more susceptible than early-season fruit. Fruit resistance was correlated with flavedo thickness, a high concentration of linalool in relation to limonene in the peel oil, and the absolute amount of oil per unit area of peel. Volatile components of the peel oil rather than gigh boiling fractions appear to account for oil toxicity. Possible applications of these findings are discussed.
