Resumo: | This research was conducted in the Laboratory of Insects Rearing (LACRI), of the Brazilian Company of Agricultural Research (EMBRAPA Maize and Sorghum Research Center) in Sete Lagoas, Minas Gerais State, Brazil. The objective was to study biological aspects of the immature phase of Eriopis connexa (Germar) (Coleoptera: Coccinellidae), with different artificial diets or preys common to the brazilian corn and sorghum agroecosystems, to develop a rearing methodology and to generate information necessary to the introduction of the predator in the crop system. The experimental design was an entirely randomized blocks, with the larvae of predator maintained in an acclimatized room, under 25±1ºC, 70±10% RH and photophase of 12 hours. The artificial diets were based on ground pet food or diets based on water, brewer's yeast and honey, with or without the addition of ferrous sulphate (FeSO4), wheat germ and soybean flour. The preys offered to E. connexa were eggs (one day or six months frozen) of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae), eggs (fresh) of Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae); eggs (fresh, one day or six months frozen) of Spodoptera frugiperda, with or without scales; recently hatched caterpillars of S. frugiperda; nymphs of Rhopalosiphum maidis (Fitch) or Schizaphis graminum (Rondani) (Hemiptera: Aphididae). All food sources were support ad libitum to E. connexa. Artificial diets, separately, did not support the development of E. connexa. Recently hatched caterpillars of S. frugiperda or eggs of A. kuehniella (six months of freezing), separately or complemented with the artificial diets, were inadequate. Eggs of A. kuehniella frozen for one day, fresh eggs of D. saccharalis, fresh eggs of S. frugiperda without or with scales, frozen for one day or six months, nymphs of S. graminum and R. maidis provided adequate development of the immature phases of the predator, evidencing the polyphagous habit of E. connexa. The results obtained also indicated the nutritional requirements of the predator and can be used to explain the success or not of E. connexa in biological control programs. Eriopis connexa adapted to different food sources, and in the field, it would not be restricted to only one source; and in this way, it could modulate its alimentary regime with alternative food, which is important for the biological control and shows its potential to control corn and sorghum pests. |

O objetivo foi estudar aspectos biológicos da fase imatura de Eriopis connexa (Germar) (Coleoptera: Coccinellidae), com diferentes dietas artificiais e presas comuns aos agroecossistemas de milho e de sorgo, visando desenvolver uma metodologia de criação e fornecer subsídios para a introdução desse predador nessasculturas. O delineamento experimental foi em blocos inteiramente casualisados, com as larvas desse predador mantidas em sala climatizada a 25±1ºC, 70±10% UR e fotofase de 12 horas. As dietas artificiais foram à base de pet food triturada e dietas contendo água, levedo de cerveja e mel, com presença ou ausência de sulfato ferroso (FeSO4), gérmen de trigo e farelo de soja. As presas oferecidas a E. connexa foram ovos de Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae), congelados por um dia ou por seis meses; ovos frescos de Diatraea saccharalis (Fabricius) (Lepidoptera: Pyralidae); ovos de Spodoptera frugiperda frescos, sem ou com escamas, congelados por um dia ou por seis meses; lagartas recém-eclodidas de S. frugiperda; ninfas de Rhopalosiphum maidis (Fitch) ou Schizaphis graminum (Rondani) (Hemiptera: Aphididae). Todas as presas e dietas artificiais foram oferecidas ad libitum a E. connexa. As dietas artificiais, isoladamente, não proporcionaram o desenvolvimento de E. connexa e lagartas recémeclodidas de S. frugiperda ou ovos de A. kuehniella (seis meses de congelamento), isoladamente ou complementados com as dietas artificiais, foram inadequados. Ovos de A. kuehniella congelados por um dia, ovos frescos de D. saccharalis, ovos de S. frugiperda frescos sem ou com escamas, congelados por um dia ou por seis meses, ninfas de S. graminum e R. maidis proporcionaram desenvolvimento adequado das fases imaturas desse predador, evidenciando o hábito polífago de E. connexa. Estudos como esse fornecem informações básicas sobre presas que suprem os requisitos nutricionais desse predador e explicações para a falha ou sucesso de E. connexa em programas de controle biológico. Eriopis connexa se adaptou a vários alimentos e, no campo, esse predador não seria restrito a um único alimento; e dessa forma, poderia modular seu regime alimentar com alimentos alternativos, o que é importante para o controle biológico e evidencia seu potencial para controlar pragas de milho e de sorgo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaJoaninhasAlimentos alternativosCriação massalPredadorControle biológicoLadybugsAlternative foodMass rearingPredatorBiological controlCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIAViabilidade de dietas artificiais e presas para Eriopis connexa (Germar) (Coleoptera: Coccinellidae)Viability of artificial diets and preys for Eriopis connexa (Germar) (Coleoptera: Coccinellidae)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf312561https://locus.ufv.br//bitstream/123456789/3885/1/texto%20completo.pdf2e92c15ccad6dade9bfe3f5f4800f1bcMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain168477https://locus.ufv.br//bitstream/123456789/3885/2/texto%20completo.pdf.txtde2b2801406bcc77f89c4b3367668958MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3567https://locus.ufv.br//bitstream/123456789/3885/3/texto%20completo.pdf.jpg7ed1d5cc4bec839fb3e14adc626d6b75MD53123456789/38852016-04-09 23:22:17.561oai:locus.ufv.br:123456789/3885Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-10T02:22:17LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
