Guava ( Psidium guajava L.) presented prominence among the tropical fruit.  Guava exports are still unimpressive, because of the quarantine pests, among them the fruit flies.  The present research had as objective to evaluate the population fluctuation of fruit flies Anastrepha spp. and the fruits infestation caused in guava accesses cultivated in organic system, and study the possible correlations between this pest and meteorological factors.  To estimate population fluctuation, 20 yellow sticky traps were used.  The reviews were initiated in April 2013, for 378 days.  The traps were kept in the field for the entire duration of the experiment, and they were reviewed every 14 days in most cases, during replacement of traps for new ones.  With the data, simple correlations were calculated between the fruit flies of the genus Anastrepha spp., the temperature, and precipitation.  Nine fruits per accession, at the stage of maturation, were taken to the laboratory and evaluated for fruit fly infestation by the longitudinal cutting of fruit. The averages were compared by the Scott-Knott test at 5% probability.  The genus Anastrepha was found in greater quantity, and there is no correlation between the meteorological factors and population fluctuation of Anastrepha .  Also was found some individuals of the species Ceratitis capitata .  Most of the fruits of the evaluated accesses presented high infestations by fruit flies.  Accesses IAC – 4 – Cica noteworthy for not presenting any infested fruit, without differing from accesses Taquaritinga Comum, both red.  The accesses Torrao de Ouro, Supreme BA, L2P4, and Supreme, also showed low numbers of fruit attacked.
