Resumo: The distribution and abundance of Ceratitis capitata in peach, guava, feijoa, hot pepper and citrus orchards was analysed in this study, as well as the efficacy of different nematodes isolates to control the medfly last instar larvae and pupae. C. capitata was present in all the field crops throughout the sampling period, although the highest number of adults was trapped during summer and autumn. The highest mean number of captured adults was observed in feijoa orchard, followed by hot pepper and citrus crops. Although in the peach orchard the mean number of trapped adults was low, the percentage of fruit infestation was similar (over 60 %) to that of feijoa, citrus and hot pepper fruits; for guava, only 24.9% of the fruits were infested by C. capitata. Regardless of the crop, all traps containing the male-attractant pheromone showed to be the most effective to estimate the distribution and abundance of the medfly. Regarding the efficacy of different isolates of nematodes those from the Heterorhabditis genera were more effective keeling both the larvae and pupae of C. capitata; however, only the isolate Az36 (H. bacteriophora) caused a larval mortality significantly higher than the control.
