Resumo: The objective of this work was to evaluate the potential control of the ant Pachycondyla obscuricornis Emery (Hymenoptera: Formicidae) on populations of nymphs of the spittlebug, Deois flavopicta Stal (Hemiptera: Cercopidae). Foraging behavior and prey consumption rate of P. obscuricornis were evaluated. Field data revealed that P. obscuricornis does not show aggressive behavior against individuals of the same species, when they are not carrying a prey; they can patrol distances larger than 10 m searching for prey, and they can build their nest as close as 1 m from each other. The ant has a solitary patrolling habit, there is no recruitment behavior, and individuals dislocate fast, browsing on soil and vegetation for prey. Predation rate on spittlebug nymphs increased relative to the spittlebug abundance, reaching 93.8% of captured prey. Pachycondyla obscuricornis is a voracious predator and may control the population of spittlebugs in cultivated pastures.

Foram estudados o comportamento de caça da formiga e sua taxa de consumo da presa. Pachycondyla obscuricornis não apresenta comportamento agressivo em relação a indivíduos da mesma espécie, quando estes não carregam presas; pode deslocar-se por distâncias superiores a 10 m em busca de presas e pode nidificar a até 1 m de ninhos da mesma espécie. A formiga apresentou hábito de caça solitário, ausência de recrutamento, e deslocamento rápido pela vegetação. A taxa de predação aumentou com a abundância da cigarrinha, chegando a representar 93,8% das presas capturadas. Pachycondyla obscuricornis é predadora voraz e representa potencial agente de controle de populações da cigarrinha-das-pastagens em pastagens cultivadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSujii, Edison RyoitiGarcia, Maria AliceFontes, Eliana Maria GouveiaO'Neil, Robert James2004-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6815Pesquisa Agropecuaria Brasileira; v.39, n.6, jun. 2004; 607-609Pesquisa Agropecuária Brasileira; v.39, n.6, jun. 2004; 607-6091678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6815/3871info:eu-repo/semantics/openAccess2014-07-22T18:20:33Zoai:ojs.seer.sct.embrapa.br:article/6815Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-22T18:20:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
