Diversidade de Anastrepha schiner, 1868 (Diptera: tephritidae) no Parque Nacional da Serra da Bodoquena-MS, Brasil

Abstract

The fruit flies (Tephritidae) comprise approximately 5,000 species, distributed in six subfamilies and approximately 500 genera, of which six are of economic importance for the fruit growing of Brazil and the world. In Brazil the genus Anastrepha is present in the pomicultura being the genus that causes greater loss to the fruit trees and some greenery. Research on the diversity of Tephritidae has been intensified in several regions of Brazil and the world, providing essential information for the selection of strategies for population monitoring and control, as well as management of beneficial insect populations in natural ecosystems and agroecosystems. In this way, this work aimed to perform a bibliographical review on the species of Anastrepha occurring in the state of Mato Grosso does Sul, its cataloged hosts. In addition, the geographic distribution in Brazil of the species occurring here was reviewed (Chapter 1). Chapter 2 presents the diversity of Anastrepha species sampled within the Serra da Bodoquena National Park. The collections were carried out from December 2016 to January 2018 at three sites, using 16 McPhail traps baited with food attractant (corn hydrolyzed protein), totaling 48 traps. The captured specimens were identified in the Laboratory of Taxonomy and Systematics of Insects (LabTaxon), Federal University of Grande Dourados-UFGD, Dourados-MS. Sixteen species were obtained: Anastrepha barbiellinii; Anastrepha bezzii; Anastrepha pr. borgmeieri; Anastrepha dissimilis; Anastrepha distincta; Anastrepha elegans; Anastrepha ethalea; Anastrepha fraterculus; Anastrepha mixta; Anastrepha montei; Anastrepha obliqua; Anastrepha punctata; Anastrepha serpentina; Anastrepha sororcula; Anastrepha striata and Anastrepha turpiniae. Anastrepha baribiellinii, Anastrepha fraterculus and Anastrepha sororcula were the most abundant and predominant species during the experimental period. A. baribiellinii had the peak population in the month of September. A. fraterculus and A. sororcula were considered indicative throughout the experimental period. Anastrepha pr. borgmeieri, Anastrepha ethalea and Anastrepha mixta are reported for the first time in Mato Grosso do Sul. This research contributed to the knowledge of the population patterns of the 16 species of Anastrepha in an important Conservation Unit of Central Brazil and adds three new records of fruit flies to Mato Grosso do Sul.
