Leaf-cutting ants are widely distributed in Brazil, particularly species of the genus Atta. We therefore described the occurrence of leaf-cutting and grass-cutting ant species of the genus Atta. Five routes comprising some of the main highways in the South, Southeast, Center-West, and North of Brazil were sampled, in addition to ants received from other 82 municipalities, composing 300 municipalities sampled. This is the first comprehensive study of Atta in Brazil. The following species were found: A. laevigata, A. capiguara, A. sexdens rubropilosa, A. sexdens piriventris, A. sexdens sexdens and A. cephalotes. Atta laevigata and A. capiguara were the species present in the largest number of the Brazilian municipalities sampled. Atta laevigata assumed the position of species of greatest occurrence in the Brazilian territory. Atta sexdens piriventris was only recorded in the southern region of Brazil. Atta bisphaerica presented lower expansion than A. capiguara. Atta cephalotes and Atta opaciceps are species of very restricted occurrence. Southeastern region was characterized by the occurrence of A. capiguara and A. laevigata. Atta laevigata exhibited a generalized pattern of occurrence in the Center-West and North. Our study contributes to a better understanding of the so far unknown occurrence of leaf-cutting and grass-cutting ants within Brazil.
RESUMO:O objetivo deste trabalho foi relatar a ocorrência da cigarrinha Aethalionidae em alfavacacravo (Ocimum gratissimum L.) no município de Bandeirantes-PR. Plantas com cerca de dois anos, na fase reprodutiva, com inflorescências, flores, frutos e sementes, serviram como fonte para a coleta de ninfas e adultos das cigarrinhas. Registrou-se em alfavaca-cravo a espécie Aethalion reticulatum e a interação com as formigas Camponotus rufipes e C. crassus.Palavras-chave: Aethalionidae, cigarrinha das fruteiras, alfavaca ABSTRACT: Detection of Aethalion reticulatum (L., 1767) (Hemiptera: Aethalionidae) in clove basil (Ocimum gratissimum L.) and observations of its occurrence. The aim of this work was to report the occurrence of the leafhopper Aethalionidae in clove basil (Ocimum gratissimum) in Bandeirantes Municipality, Paraná State, Brazil. Plants around two years old, in the reproductive phase, presenting inflorescences, flowers, fruits and seeds, were used as source for collection of leafhopper nymphs and adults. In clove basil, the species Aethalion reticulatum was recorded, in addition to its interaction with the ants Camponotus rufipes and C. crassus.
