Spittlebugs (Homoptera: Cercopidae) are important pests of forage grasses in the genus Brachiaria (Trin.) Griseb. throughout the neotropics. Results of recurrent selection on resistance to spittlebugs in a synthetic brachiariagrass population are reported. The population was synthesized by recomb...

High levels of antibiotic resistance to the cercopid Aeneolamia varia (F.) were identified in accessions of the forage grass Brachiaria by means of a glasshouse bioassay. Emergence of adults from pots of Brachiaria spp. infested with eggs of A. varia ranged from 55 to 83% and 56 to 80% on suscept...

Several genera and species of spittlebugs (Homoptera: Cercopidae) are economic pests of Brachiaria spp. grasses in tropical America. To support current breeding programs aimed at obtaining multiple spittlebug resistance, we undertook a series of studies on antibiosis and tolerance as possible mec...
