Abstract. Anastrepha alveatoides Blanchard is a Diptera species native to South America, belonging to the Tephritidae family. Works published about A. alveatoides provide only records of presence but not biological or ecological information. The only association with its host plant was made in Brazil, where it was found infesting the fruit of Ximenia americana, an American Olacacea species widespread from Mexico to Argentina. The presence of A. alveatoides in La Rioja province (Argentian) remained doubtful because it was recorded as A. alveata, and then proposed as A. alveatoides only based on the distribution and not by direct observation of the specimen.Some Brazilian hymenopteran parasitoids attacking A. alveatoides were recorded, but Argentinian species are still unknown.The present study corroborated 1) the presence of A. alveatoides in La Rioja province, 2) the association between A. alveatoides and X. americana, and 3) the effects of urban areas on A. alveatoides population, and 4) the association of A. alveatoides with the eucoilid parasitoid Ganaspis pelleranoi. Results support the existence of a possible co-evolution between these species, which encourages further studies on this interesting three-trophic interaction.
