Resumo: Adults of Zulia entreriana (Berg.) and Deois flavopicta (Stal) collected in ten sweep samples of a sweep-net and transferred to cages using an aspirator tended to live shorter than those transferred using a container lined with cotton. Sweeping itself did not affect the adult survival. Adults collected in 10, 30 or 50 sweep samples lived the same period as those captured by pulling an open end of a cage 20 cm above the pasture at 30º angle. Spittlebugs collected at 8 a.m. - 9 a.m. lived longer than those collected at midday - 1 p.m. or 5 p.m. - 6 p.m. More adults were captured by sweeping at 5 p.m. - 6 p.m. than at 8 a.m. - 9 a.m. or midday - 1 p.m. A comparison of sexual proportions of adult captured by sweeping with those based on all the adults in 1 m2 pasture areas showed that the sweep-net method tended to underestimate the proportion of females.

A amostragem propriamente dita pela rede não afetou a sobrevivência dos adultos. Adultos coletados nas amostras de 10, 30 ou 50 batidas sobreviveram o mesmo tempo quanto os capturados arrastando-se o lado aberto de uma gaiola 20 cm acima do pasto em ângulo de 30º. As cigarrinhas coletadas às 8 h - 9 h, sobreviveram mais tempo do que as coletadas às 12 h - 13 h ou 11 h - 18 h. Foi obtido maior número de adultos utilizando-se a rede entomológica às 17 h - 18 h do que às 8 h - 9 h ou às 12 h - 13 h. A comparação das proporções sexuais de adultos capturados pelo uso da rede entomológica com os baseados na captura de todos adultos em áreas de 1 m2 de pasto mostrou que o método da rede entomológica tendeu a tornar menor a proporção de fêmeas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNilakhe, Shashank S.Hewitt, George B.Paschoal, Gustavo O.Buainain, Conceição M.Souza, Antonia R.
