P.  aFirst Report of Metadelphax propinqua (Fieber) (HemipterabDelphacidae) Feeding on Bermudagrass in Brazil.h[electronic resource]  c2024  aBermudagrass (Cynodon dactylon (L.) Pers., Poaceae) is one of the most important pasture grasses used in milk production  systems in southern Brazil, with an increasing expansion of cultivated areas in recent years. Here, we report the frst  occurrence of the planthopper Metadelphax propinqua (Fieber) (Hemiptera: Delphacidae) feeding on bermudagrass in Brazil.  Population outbreaks of this species were observed in January/February 2023 in a commercial hay production farm in the  municipality of Chapecó, Santa Catarina State, southern Brazil. Metadelphax propinqua was found in association with three  cultivars of C. dactylon (Tifton 85, Jiggs, and Vaquero). The infested plants showed leaf chlorosis and a reduced plant growth  rate due to sap sucking and toxin injection as well as honeydew deposition on the leaves, which led to the development of  sooty mold. In addition, this delphacid species has been reported as a vector of important pathogens to bermudagrass species  and other row crops. Thus, M. propinqua is a potential pest of bermudagrass in Brazil and should be monitored to assess its  establishment and behavior in Brazilian pasturelands.  aCynodon dactylon  aInsect vector  aInsect-plant interactions  aPlanthopper1 aSAVARIS, D.
