Abstract

We report the first records in Brazil of Diocalandra frumenti (Fabricius) and Polytus mellerborgii (Boheman), weevil species of potential phytosanitary concern. These detections were made through surveys in the Entomological Collection of the Universidade Federal Rural de Pernambuco (CERPE) and targeted field inspections in northeast Brazil. These findings expand the known distribution of these weevils in Brazil and underscore the need for enhanced phytosanitary surveillance due to their potential impact on crop production in other countries and the implications for quarantine regulations.
