Análise faunística e flutuação populacional de moscas-das-frutas (Diptera: Tephritidae) em cultivos de aceroleira, mangueira e goiabeira em três propriedades no município de Brasil Novo, Pará

Abstract

Fruit flies are phytophagous insects that stand out in fruit growing due to impacts on fruits, mainly by the larvae that consume the pulp. The survey of the diversity of these tephritids is still scarce in the country, especially in the Amazon region, so the objective of this work was to survey the biodiversity of fruit flies in the municipality of Brasil Novo, Pará. For studies of faunistic analysis and fluctuation population, tephritid samples were collected weekly with the aid of 18 McPhail traps. In the traps 5,849 individuals were obtained, with 12 species identified of Anastrepha nine morphotypes. In the fruit samples, 7,650 tephritid pupae were obtained, A. obliqua in guava fruits (2.07%), hose (90.26%) and acerola (7.66%) and A. striata on fruits of guava (98.8%) and acerola (1.19%). The following species of parasitoids associated were found in hose and acerola fruits associated with A. obliqua: Aganaspis pelleranoi, Doryctobracon areolatus, Odontosema albinerve, Opius bellus and Utetes anastrephae, and the species associated with A. Striata in guava fruits were A. pelleranoi, D. areolatus, O. albinerve, O.bellus, U. anastrephae and Pachycrepoideus vindemia.
