Resumen
Los pentatómidos (Hemiptera: Pentatomidae) son un grupo de unas 5.000 especies distribuidas por todo el mundo, muchas de ellas fitófagas con implicaciones económicas como plagas de cultivos. El arroz (Oryza sativa L.) es uno de los productos agrícolas más relevantes para el consumo humano. En los arrozales neotropicales, los hemípteros son las principales plagas, siendo los pentatómidos los que más afectan a la productividad del cultivo, destacando el género Tibraca Stål en cuanto al impacto económico. Además, los cultivos de arroz pueden representar importantes sitios de alimentación y apareamiento para otras especies de chinches taxonómicamente relacionadas con Tibraca, que podrían desempeñar el papel de potenciales plagas, lo que hace necesario el estudio de los pentatómidos asociados a este cultivo en el Neotrópico. Este trabajo tuvo como objetivo reportar la presencia de Glyphepomis adroguensis Berg, Hypatropis inermis (Stål) y Paratibraca spinosa (Campos & Grazia) asociadas al arroz en las principales zonas productoras de Argentina. Se identificó el material recolectado durante 2017-2018 en arrozales comerciales del Noreste argentino, principal región productora. Asimismo, se consideró la variedad de arroz sobre la que se recolectaron los especímenes, el estado del cultivo (temporada de cultivo - postcosecha) y la fenología del cultivo. Como resultado, se reporta la asociación de las especies mencionadas con el arroz en las provincias de Chaco y Corrientes, Argentina. Además, se reporta por primera vez en el país el género Paratibraca Campos & Grazia y la especie P. spinosa.
Stink bugs (Hemiptera: Pentatomidae) are a group of about 5,000 species distributed worldwide, many of them phytophagous with economic implications as crop pests. Rice (Oryza sativa L.) is one of the leading agricultural products for human consumption. In neotropical rice fields, hemipterans are the primary pests, with stink bugs being the worst affecting crop productivity, standing out the genus Tibraca Stål in terms of economic damage. In addition, rice crops may represent important feeding and mating sites for other stink bug species taxonomically related to Tibraca, which could play the role of potential pests, making it necessary to study the pentatomids associated with this crop in the Neotropics. This work aimed to report the presence of Glyphepomis adroguensis Berg, Hypatropis inermis (Stål) and Paratibraca spinosa (Campos & Grazia) associated with rice in the main rice-growing areas of Argentina. Material collected during 2017-2018 from commercial fields in northeastern Argentina, the central rice-producing region, was identified. The rice variety on which the specimens were collected, crop status (growing season - post-harvest) and crop phenology were considered. As a result, the association of the mentioned species with rice in the provinces of Chaco and Corrientes, Argentina, is reported. Moreover, the genus Paratibraca Campos & Grazia and the species P. spinosa are reported for the first time in the country.
