Tópico(s)Insect-Plant Interactions and Control
ResumoBrazilian livestock is an activity of huge economic importance, and is directly related to the forage grass pastures on which the animals feed. Plant chlorosis, or “pasture burning”, is caused by the feeding activity of spittlebugs (Hemiptera: Cercopidae), and hinders the photosynthetic process of the plant and its growth. As damage varies depending on the type of grass and on the spittlebug species, information about the distribution of Cercopidae and their host plants is essential for the proper management of these insects. The present study aimed to increase the knowledge about the pasture spittlebugs - Deois (Pandysia) schach (Fabricius, 1787) and Mahanarva (Ipiranga) integra (Walker, 1858) - and their host plants (forage grasses) for the state of Santa Catarina, Brazil. Specimens were collected with a sweeping net on the dates of December 15, 2019 and March 19 and 24, 2020, in the city of Dona Emma, in crops of missionary grass (Axonopus catharinensis Valls cv. Missioneira) and elephant grass (Cenchrus purpureus (Schumach.) Morrone). A total of 51 specimens of spittlebugs were collected, identified as Deois (Pandysia) schach (Fabricius, 1787) (33 specimens) and Mahanarva (Ipiranga) integra (Walker, 1858) (18 specimens), both occurring in the two grass species. The record of D. schach in elephant grass was already known, but not for the state of Santa Catarina; both records of M. integra consist of new host plant records for this species. The study contributes to the registration of host plants of these spittlebugs in the state of Santa Catarina.
