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.
