Abstract
This study reports Pachybrachis sp. association with a new host, Spermacoce verticillata L. (Rubiaceae). It synthesizes Brazil locality records and host plant records from literature. Specimens of adults and larvae were collected on the host in an urban area of Maceió, Alagoas, Brazil. Larvae and adults were reared on the host plant in the laboratory, using fresh plant tissue daily.
Highlights
Spermacoce verticillata L. (synonym: Borreria verticillata (L.) G
Known as “shrubby false buttonweed” (GBIF 2021a), S. verticillata is a native herb from tropical America, but it is considered a weed in Brazil probably due to its tolerance to nutrient-poor soils and the easy dispersal of its seeds (Lorenzi 1991)
We report a new record of Pachybrachis sp. whose adults and immature stages are in association with S. verticillata in Brazil
