N2 - We investigated the influence of the physiological state of young female Ceratitis capitata (Diptera: Tephritidae) on resource foraging behavior and mating propensity in field cage studies. Three kinds of diets were supplied prior to release on host plants: (1) 2% sucrose, (2) 20% sucrose, and (3) protein hydrolysate. Laboratory-cultured C. capitata females of different ages, ranging between 3-9 days old, were released in field cages containing two potted citrus tree seedlings, each consisting of either proteinacous or carbohydrate sources. Flies 3-7 days old, exposed to 2% sucrose, showed no preference for either source, while other groups, at the same age, displayed a significant influence of diet. Conversely, the behavior of flies within the age 8-9 days old was governed only by their reproductive needs, all three groups being significantly attracted to protein. In additional field-cage studies, mating propensity of similar groups was observed. Copulation was significantly higher among immature flies fed on proteinacous diet than those exposed to carbohydrate sources prior to their release.
