Resumo: This work studied the biological aspects and daily rhythm of the activities (mating, oviposition, searching and predation) of Porasilus barbiellinii Curran, 1934 (Diptera, Asilidae) predator of the froghopper Deois flavopicta (Stal, 1854) (Homoptera, Cercopidae). The field study was carried out in a pasture of Brachiaria decumbens Stapf located in the municipality of Três Corações, State of Minas Gerais, Brazil, in three five-day periods, for nine hours a day. The laboratory observations were conducted in the Entomology Laboratory of Crop Protection Department of ESAL, Lavras, MG (temperature 25 ± 1°C; relative humidity 70 ± 10% and photophase fourteen hours). The egg period was an average seven days and the larvae took, on average two minutes to free themselves from the corium. A peak of activity of mating occurred from eight nine a.m. and other from four - five pm. High temperature favored oviposition which took place most frequently between eleven a.m. and two p.m. The asilid flies exercised its searching activity from eight a.m. - five p.m. The most significant time for predation by both males and females was from two - three p.m.

O estudo de campo foi conduzido em pastagem de Brachiaria decumbens Stapf no município de Três Corações, MG, em três períodos de cinco dias, durante nove horas por dia. As observações de laboratório foram realizadas no Laboratório de Entomologia do Departamento de Fitossanidade da Escola Superior de Agricultura de Lavras (ESAL), Lavras, MG. (Temperatura 25 ± 1ºC; umidade relativa 70 ± 10% e fotofase quatorze horas). O período embrionário médio foi de sete dias, e as larvas demoraram, em média, dois minutos para se livrarem inteiramente do córion. Um pico de atividade de acasalamento ocorreu entre oito - nove horas e outro entre 16 - 17 horas. A temperatura foi um fator ambiental importante para a oviposição, observando-se maior número de posturas nas horas mais quentes do dia (onze às quatorze horas). Os asilídeos exercem sua atividade de busca das oito às 17 horas, O horário mais significativo para a predação tanto para machos como para fêmeas, foi das quatorze às quinze horas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBueno, Vanda Helena Paes2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14745Pesquisa Agropecuaria Brasileira; v.22, n.09/10, set./out. 1987; 903-915Pesquisa Agropecuária Brasileira; v.22, n.09/10, set./out. 1987; 903-9151678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14745/12116info:eu-repo/semantics/openAccess2014-10-10T17:19:56Zoai:ojs.seer.sct.embrapa.br:article/14745Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-10T17:19:56Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
