Anastrepha ludens (Loew) developmental time and egg clutch size were determined in grapefruit (Citrus paradisi Macf.), orange (Citrus sinensis Osbeck), mango (Mangifera indica L.), and peach (Prunus persica L.), and the suitability of citrus was determined for A. ludens development to adulthood in the laboratory. Developmental time for immature stages of A. ludens varied with host fruit species. Egg incubation required 3.8, 4.3, 4.6, and 3.8 d, and larvae developed in 27.4, 29.7, 22.3, and 10.3 d in grapefruit, orange, mango, and peach, respectively. Pupae developed in 17.1, 13.7, 14.2, and 13.0 d in the fruit mentioned above, respectively. Larger egg clutches were oviposited in peach than in the other tested fruit. Suitability of citrus for development of A. ludens immatures varied with fruit species and varieties. 'Marsh' and 'Ruby Red' grapefruit were more suitable for A. ludens immatures development than 'Valencia' orange. Peach susceptibility to A. ludens increased as the ripening process advanced. The egg clutch size and development of immature A. ludens are thought to be related to pulp compactness, albedo thickness in citrus, and resistance of rind to penetration.
