Using a simulation model as an analysis tool, the economic impact of spittlebugs in pastures of Colombia was quantified in terms of animal production. Three levels of abundance (10, 25, 50 adults/m2 ) and farm area affected (25, 50, 100%) were evaluated using data obtained in Brazil for Notozulia...

La primera detección del salivazo Prosapia simulans (Walker) para Colombia en 1999, fue una voz de alerta para ganaderos y cañicultores del Valle del Cauca donde ya alcanza niveles económicos en Brachiaria. A pesar de su importancia en pastos y caña en Centroamérica, se conoce poco sobre su biolo...

Mahanarva bipars (Walker) is identified as the species causing the first spittlebug outbreak in Colombian sugarcane. Information on the biology, host plants and geographic range are absent from the literature. Therefore, we summarize field observations on infestation levels and location of feedin...

Two methodologies for rearing grass-feeding spittlebugs are described and were evaluated with Aeneolamia varia (Fabricius) on Brachiaria ruziziensis Germ. & Evrard. To promote biological studies, a new small-scale rearing unit was developed to maintain spittlebug life stages in the greenhouse yea...

The genus Prosapia Fennah and P. simulans (Walker) are reported for the first time in South America, based on recent field collections in Colombia and museum specimens from Venezuela. Prosapia simulans was found on Axonopus micay García-Barr., Brachiaria decumbens Stapf, B. dictyoneura (Fig. & De...
