Abstract

First records of the sugar cane and forage grass pest, Prosapia simulans (Homoptera: Cercopidae), from South America.

Abstract

The genus Prosapia and P. simulans are thought to be reported for the first time in South America, based on recent field collections (1999-2000) in Colombia and museum specimens from Venezuela. P. simulans was found on Axonopus micay, Brachiaria decumbens, B. dictyoneura, Cynodon plectostachyus, Hyparrhenia rufa and Saccharum officinarum. Persistent field populations were detected from 1060-1621 m elevation, principally associated with B. decumbens, reaching economic levels in one of the observed sites. On two occasions P. simulans was found on sugarcane. Evidence suggests that this Central American sugarcane and forage grass pest is a well established new arrival, thereby representing a new threat to pasture production and potential threat to cane production in Colombia's Cauca Valley. The distribution, bionomics, and pest status of P. simulans are summarized, and its mode of introduction and potential pest status are discussed.
