Fruit flies (Diptera: Tephritidae) and their parasitoids associated with acerola, mango, and guava in the municipality of Brasil Novo, Pará

Abstract

ABSTRACT Fruit flies are phytophagous insects that are important because of the damages caused to fruits, mainly by larvae that feed on the pulp. Surveys of the diversity of these tefritids are still scarce in Brazil, especially in the Amazon region, the objective of this study was to establish the tritrophic relationship existing between species of Anastrepha, their parasitoids, and the fruits acerola (Malpighia emarginata DC.), mango (Mangifera indica L.), and guava (Psidium guajava L.) in the municipality of Brasil Novo, Pará. Freshly fallen fruits were collected weekly from January to December 2018, in three farms. Throughout the survey, 4,324 puparium were collected in guavas, 2,682 in mangoes, and 644 in acerolas. The species Anastrepha obliqua (Macquart, 1835) were identified in mango (90.3%), acerola (7.7%) and guava (2.1%), and Anastrepha striata Schiner, 1868 were identified in guava (98.8%) and acerola (1.2%). Five species of parasitoids were identified in association with A. obliqua and six species of parasitoids were identified in association with A. striata. The specie Doryctobracon areolatus (Szépligeti, 1911) was the most frequent among the species of parasitoids recorded.
