Resumo: | The sustainable management of pests is one of the challenges of modern agriculture. One possibility to reduce pest attack on crops is to enhance the abundance and to increase the effectiveness of natural enemies via diversification of crop area with plants that provide extra food source for predators and parasitoids. The objective of this thesis is to study the suitability of food produced by plants to natural enemies. In Chapter I, the suitability of nectar produced by buckwheat and by castor bean, plants with potential use in agroecossystem diversification, was evaluated as food source for the generalist predador Chrysoperla externa. The survival of larvae and adults of C. externa was higher when they fed on buckwheat floral nectar and on castor bean extrafloral nectar, than when they had no access to these nectars. In Chapter II, a combination of a carbohydrate (buckwheat nectar) and a protein food (sunn hemp pollen) was evaluated for survival and reproduction of C. externa. The addition of sunn hemp pollen to buckwheat nectar diet increased C. externa survival. The reproductive success of C. externa was similar when adult females fed only sunn hemp pollen and when buckwheat nectar was added to the pollen diet. Having found that buckwheat nectar is suitable for a generalist predator, I continue investigating its use by other members of the arthrropod food web preseny in coffee agroecosystems. Thus, in Chapter III, the use of buckwheat nectar by an important coffee pest, the coffee leaf miner Leucoptera coffeella and by its parasitoid Mirax sp. was evaluated. Survival of both, pest and parasitoid, was increased in the presence of buckwheat nectar. However, feeding on buckwheat nectar decreased its reproductive success. Together, these results show the potential of buckwheat, castor bean and sunn hemp for use in biological conservation control, especially in coffee agroecosystems. |

Uma possibilidade para reduzir ataque de pragas sobre os cultivos é aumentar o número e a eficiência de inimigos naturais através da diversificação de área de plantio com plantas que forneçam fontes alternativas de alimentos para predadores e parasitóides. O objetivo desta tese é estudar a viabilidade de alimento produzido por plantas para inimigos naturais. No capítulo I, a viabilidade do néctar produzido pelo trigo mourisco e pela mamona, plantas com potencial de uso na diversificação de agroecossistemas, foi avaliado como fonte de alimento para o predador generalista Chrysoperla externa. A sobrevivência de larvas e adultos de C. externa foi maior quando se alimentaram de néctar floral de trigo mourisco e do néctar extrafloral da mamona do que quando esses predadores não tiveram acesso a esses néctares. No capítulo II, foi avaliada a adição conjunta de fonte de carboidrato (néctar de trigo mourisco) com alimento proteico (pólen de crotalária) para a sobrevivência e reprodução de C. externa. A adição de pólen de crotalária ao néctar de trigo mourisco aumentou a sobrevivência de C. externa. O sucesso reprodutivo de C. externa foi semelhante quando fêmeas adultas se alimentaram somente de pólen de crotalária e quando néctar de trigo mourisco foi adicionado na dieta com pólen. Tendo encontrado que o néctar do trigo mourisco é viável para o predador generalista, continuou-se a investigar o uso dessa fonte de alimento para outros artrópodos presentes no agroecossistema cafeeiro. Desse modo, no capítulo III foi avaliado o uso do néctar do trigo mourisco pelo bicho mineiro Leucoptera coffeella, uma importante praga do sistema cafeeiro e por um de seus parasitóide, Mirax sp.. A sobrevivência de ambos, praga e parasitóide, foi aumentada na presença do néctar do trigo mourisco. Porém, se alimentando do néctar do trigo mourisco, o bicho mineiro teve o seu sucesso reprodutivo diminuído. Juntos, os resultados dessa tese mostraram o potencial do trigo mourisco, da mamona e da crotalária para o uso no controle biológico conservativo, especialmente no sistema cafeeiro.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaChrusoperia externaParasitóideCaféControle biológicoLeucoptera coffeellaChrysoperla externaParasitoidsCoffeeBiological controlLeucoptera coffeellaCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::ENTOMOLOGIA AGRICOLAPlantas favoráveis a agentes de controle biológicoPlants favorable to biological control agentsinfo: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/pdf283358https://locus.ufv.br//bitstream/123456789/4011/1/texto%20completo.pdf8cb5f40c4c335c506afac7b5547897aeMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain88241https://locus.ufv.br//bitstream/123456789/4011/2/texto%20completo.pdf.txt64202b78fefdb42dc648e42c4a115005MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3621https://locus.ufv.br//bitstream/123456789/4011/3/texto%20completo.pdf.jpgce38f7ca223fd0bfce4240f36bff50f7MD53123456789/40112016-04-09 23:13:59.423oai:locus.ufv.br:123456789/4011Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-10T02:13:59LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
