Abstract
Phytomonas elmassiani was found in 333 of 408 Asclepias curassavica from 13 localities in Colombia and in 14 of 40 from 4 sites in Costa Rica. In Colombia similar flagellates were found in A. fruticosa and in a wild asclepiad vine Sarcostemma clausum in areas where A. curassavica was abundant and harbored intense infections. The parasite was transmitted to laboratory-raised A. curassavica and A. fruticosa by wild, naturally infected Oncopeltus cingulifer and O. unifasciatellus as well as by laboratory-infected nymphs of both species. In wild-caught insects, only O. cingulifer had flagellates in the salivary glands; it is probably the main vector-host locally.
