Diversity of fruit flies (diptera: tephritidae) in a private natural heritage reserve in the atlantic forest domain near the Brazil-Paraguay border ; Diversidade de moscas-das-frutas (diptera: tephritidae) em uma reserva particular do patrimônio natural do domínio mata atlântica próxima à fronteira Brasil-Paraguai

The scarcity of studies on the ecology of Tephritidae in Conservation Units (UCs) underscores the importance of knowing the diversity and population patterns of fruit fly species. Thus, the aimed was to carry out a survey of the species of fruit flies existing in the Private Natural Heritage Reserve (RPPN) FAFI, Itamarati II, Ponta Porã - MS, in order to provide knowledge of populations that can be used as a source data in the development of future management and monitoring plans. The samplings were carried out from December 2019 to December 2020. A set of 12 McPhail model traps were used and three types of food baits (BioAnastrepha®) based on (hydrolyzed corn protein) with 250 ml of food attractant, (Ceratrap®) at 5% vol., (guava juice) at 100% with monthly sampling. The traps were placed approximately 250m apart from each other, in trees, at 1.70m from the ground level, on the four main tracks, which depart from the buffer zone to the interior of the Conservation Units. In total, 12 traps were installed, being 3 traps per 4 tracks, the traps remained fixed in the points allocated in the 4 tracks for a period of one year. After one week, in the field, the traps were removed and the fruit flies were sorted, quantified ♂ and ♀, identified the species and stored in 90% ethanol. There were 17 species of Anastrepha, being A. obliqua, A. fraterculus, A. sororcula, and A. striata, the predominant species (most abundant and frequent) during the experimental period. A. obliqua had its peak in December. A. fraterculus and A. sororcula were indicative of the flora of the CU and occurred throughout the entire sampling period. This information contributes to the understanding of the entomofauna in the interior of the (RPPN) and helps in the management and conservation plan of this important Conservation Unit in the Brazilian Midwest. ; A escassez de estudos sobre ecologia de Tephritidae em Unidades de Conservação (UCs) ressalta a importância de conhecer a diversidade e padrões populacionais das espécies de ...
