Evaluation of spittlebug incidence on two grasslands from Mojui Dos Campos Para, Brazil

摘要

Spittlebugs (Homoptcra: Cercopidae) arc considered the main pests of forage crops, particularly of the genus Brachiaria (Miles et al. 2006) with severe damage caused by the sucking of nymph and adult insects which often leads to reduced dry matter production and forage quality, and may result in death of the above-ground part of plants when spittlcbug populations arc high (Holmann and Peck 2002). In Brazil, spittlcbug incidence is one of six major causes for degradation of Amazon pasture degradation.
