Spittlebugs (Hemiptera: Cercopidae) are the predominant pasture pests in Brazil, mainly the Amazonia region. Despite frequent reports of attacks by these spittlebugs in Roraima, information on this insect group is scarce. Therefore, we conducted surv

Spittlebugs are the most damaging pasture pests in tropical America where extensive monocultures of Brachiaria decumbens cv. Basilisk have favoured the builup of spittlebug populations. Under servere spittlebug attack, the entire above-ground portion
