Entomofauna de besouros e formigas associados à plantio de uva em São João do Piauí - PI

Abstract

The grapevine (Vitis vinifera L.) is a crop of great economic importance in Brazil, especially in the Northeast region. Although viticulture is developing in the municipality of São João do Piauí – PI, information about the entomofauna associated with this crop is still scarce. Beetles and ants play an important ecological role in agricultural ecosystems, acting as pests, natural enemies, or bioindicators. The objective of this study was to identify the entomofauna of beetles and ants associated with viticulture in the municipality of São João do Piauí, using different types of traps. The research was conducted at the Marrecas Settlement with the aid of ethanol traps (Carvalho-47 model), pitfall traps, and Moericke traps. The collected specimens were stored in labeled vials indicating location, date, and type of trap, and taken to the Biology Laboratory of the Federal Institute of Piauí, São João do Piauí campus, for sorting. Subsequently, the specimens were sent to specialists for species-level identification. Based on the results obtained, the first record of occurrence was reported, for the municipality of São João do Piauí – PI, of the following beetle species: Canthidium manni, Canthon sp., Coprophanaeus (Metallophanaeus) (Arnaud, 2002), Coprophanaeus pertyi (Olsoufieff, 1924), Deltochilum pseudoicarus (Balthasar, 1939), Deltochilum sp., Deltochilum verruciferum, Dichotomius geminatus, Dichotomius nisus (Olivier, 1789), Omorgus suberosus (Fabricius, 177), Ontherus appendiculatus (Mannerheim, 1828), Pheropsophus sp., Sylvicanthon enkerlini (Martinez, Halffter & Halffter, 1964), Tenebrionidae sp. 1, Tenebrionidae sp. 2, Tetraechma liturata (Germar, 1813), Acromyrmex landolti (Forel, 1885), Camponotus aff. atriceps (Smith, 1858), Camponotus crassus (Mayr, 1862), Crematogaster sp. 1, Dorymyrmex sp. 1, Eciton aff. quadriglume (Haliday, 1836), Ectatomma muticum Mayr, 1870, Ectatomma muticum Mayr, 1871, Ectatomma muticum Mayr, 1872, Ectatomma muticum Mayr, 1873, Labidus coecus (Latreille, 1802), and Solenopsis sp. 1. Therefore, this study opens the door to an unknown universe in São João do Piauí, indicating that there is still much to learn about the fauna that affects local viticulture. And yes, from the interior of Piauí, an important contribution to entomology, agriculture, and Brazil can emerge.
