Diversidade de moscas-das- frutas (Diptera: Tephritidae) na região de fronteira Brasil - Paraguai

Abstract

Fruit flies belong to the Tephritidae family, which is one of the largest in the Diptera order. They constitute one of the main groups of phytophagous insects, with economic importance. Studies on this group are still neglected, and little is known about their habits. Hence, this work aimed to carry out an inventory of fruit fly species (Diptera: Tephritidae) that occur in a forest reserve in the municipality of Ponta Porã - MS, Brazil (Chapter 1). Collections were carried out from October 2013 to November 2015 using 6 McPhail traps baited with food attractant (hydrolyzed corn protein). The specimens captured were identified at the Laboratory of Taxonomy and Systematics of Insects (LabTaxon), Federal University of Grande Dourados - UFGD, Dourados - MS. Ten species of Anastrepha were obtained: A. punctata, A. daciformis, A. sororcula, A. montei, A. dissimilis, A. fraterculus, A. striata, A. gradis, A. obliqua, and A. pseudoparallela. However, A. montei was the predominant species, with a peak population of capture in April. A. dissimilis, A. grandis, A. striata were considered indicators throughout the experimental period. This research contributed to the knowledge of population patterns of 10 Anastrepha species in an important Conservation Unit in Brazil, where they show records of fruit fly species occurring in Mato Grosso do Sul.
