ABSTRACT Citriculture is a growing industry in Pará state, Brazil, but information regarding fruit flies and their associated parasitoids in this region is lacking. To address this gap in knowledge, we collected oranges (Citrus sinensis), lime oranges (C. sinensis), common sweet limes (C. limettioides), citrons (C. medica) and mandarins (C. reticulata). We recorded field infestation by Anastrepha obliqua in C. sinensis under natural conditions for the first time in the study region, and a tritrophic relationship between C. sinensis, A. obliqua, and the parasitoids Opius bellus and Asobara anastrephae was identified.
RESUMO A citricultura está crescendo no Estado do Pará, Brasil, mas faltam informações sobre as pragas conhecidas como moscas-das-frutas e os parasitoides associados na região. Visando abordar esta lacuna no conhecimento, foram coletados frutos de laranja (Citrus sinensis), laranja var. lima (C. sinensis), lima-da-pérsia (C. limettioides), limão-cidra (C. medica) e tangerina (C. reticulata). Registramos, pela primeira vez, infestação em condições naturais de campo por Anastrepha obliqua em C. sinensis no Pará e identificamos uma tritrófica entre C. sinensis, A. obliqua e os parasitoides Opius bellus e Asobara anastrephae.
