Resumo: Triozoida limbata is one of the most important pests of guava plants. Their nymphs attack young leaves and buds, causing serious damages. Basic studies of population dynamics and determination of factors that regulate the population growth are necessary for the development of integrated programs management of this pest. Agents of natural biological control and the climatic elements are among the factors that more affected the attack intensity of insects-pest. Objective this work was assessed T. limbata population fluctuation and determines the relationship among its occurrence with natural enemies and climatic elements. This research was carried out in a commercial orchard of guava, located in Paula Cândido, Minas Gerais state, from julho/2005 to agosto/2007. Population densities of T. limbata, predators, parasitoids and parasitism rates of nymphs were assessed weekly. Climatic data were also collected daily. Correlations were accomplished among T. limbata densities with the natural enemies population densities and with data climatic elements for determine the relationship among these factors. T. limbata was verified guava plants groves to year, and in most of the time this insect reached the pest status. Seasonality of T. limbata attack to guava plants was associated to variations of climatic elements and predators and parasitoids densities. Populational peaks of eggs, nymphs and adults occurred from August to December, from July to November and from August to November, respectively. The largest intensity of T. limbata attack to guava plants occurred in periods of cool temperatures (18 to 20 ºC) and shorter photoperiod (10 at 11 hours of light). Natural enemies that controlled T. limbata were the predators Chrysoperla sp. (Neuroptera: Chrysopidae), Harmonia axyridis (Coleoptera: Coccinellidae), Acanthinus sp. (Coleoptera: Anthicidae), Discodon sp. (Coleoptera: Cantaridae), Hymenoptera: Vespidae and the parasitoid of nymphs Psyllaephagus sp. (Hymenoptera: Encyrtidae). Results found in this work, the future studies aiming the determination of strategies and tactics management of T. limbata should consider its occurrence time and factors related with the seasonal variations of their populations, like the climatic elements and the natural enemies.

Suas ninfas atacam as folhas de brotações novas, causando sérios danos. Para desenvolvimento de programas de manejo integrado dessa praga são necessários estudos básicos de dinâmica populacional e determinação de fatores que regulam o seu crescimento populacional. Entre os fatores mais importantes que afetam a intensidade de ataque dos insetos-praga estão os agentes de controle biológico natural e os elementos climáticos. Assim, este trabalho teve por objetivo avaliar a flutuação populacional de T. limbata e determinar a relação entre a ocorrência de T. limbata com os inimigos naturais e os elementos climáticos. O trabalho foi realizado em pomar comercial de goiabeira, localizado em Paula Cândido, MG de julho de 2005 a agosto de 2007. Foram avaliadas, semanalmente, as densidades populacionais de T. limbata, de predadores, parasitóides e a taxa de parasitismo de ninfas. Dados climáticos também foram coletados diariamente. Correlações entre as densidades de T. limbata com as densidades populacionais dos inimigos naturais e os dados dos elementos climáticos foram realizadas para determinação da relação entre estes fatores. T. limbata atacou a cultura da goiabeira durante o ano inteiro, sendo que na maior parte do tempo este inseto atingiu o status de praga. A sazonalidade do ataque de T. limbata à goiabeira esteve associada a variações nos elementos climáticos e nas densidades de predadores e de parasitóide. Os picos populacionais de ovos, ninfas e adultos ocorreram nos meses de agosto a dezembro, julho a novembro e agosto a novembro, respectivamente. A maior intensidade de ataque de T. limbata à goiabeira ocorreu em períodos de temperaturas amenas (18 a 20 ºC) e menor fotoperíodo (10 a 11 horas de luz). Os inimigos naturais que exerceram controle sobre T. limbata foram os predadores Chrysoperla sp. (Neuroptera: Chrysopidae), Harmonia axyridis (Coleoptera: Coccinellidae) Acanthinus sp. (Coleoptera: Anthicidae), Discodon sp. (Coleoptera: Cantaridae), Hymenoptera: Vespidae e o parasitóide de ninfas Psyllaephagus sp. (Hymenoptera: Encyrtidae). Mediante aos resultados encontrados neste trabalho, os estudos futuros visando a determinação de estratégias e táticas de manejo de T. limbata devem levar em consideração a sua época de ocorrência e os fatores relacionados com as variações sazonais de suas populações, como os elementos climáticos e os inimigos naturais.Faculdade Univértixapplication/pdfporUniversidade Federal de ViçosaMestrado em EntomologiaUFVBRCiência entomológica; Tecnologia entomológicaPsilídeo da goiabeiraPsidium guajavaDinâmica populacionalPredadoresParasitóidesPsidium guajavaPopulation dynamicsPredatorsParasitoidsCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOSSANIDADE::ENTOMOLOGIA AGRICOLAVariação sazonal de Triozoida limbata (Hemiptera: Triozidae) e inimigos naturais em goiabeiraSeasonal variation of Triozoida limbata (Hemiptera: Triozidae) and natural enemies in guava plantsinfo: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/pdf306198https://locus.ufv.br//bitstream/123456789/3860/1/texto%20completo.pdf8f1faae152b473ab728693d836276bd4MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain97531https://locus.ufv.br//bitstream/123456789/3860/2/texto%20completo.pdf.txtf3b4266d70cb708a4072a5228341997dMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3639https://locus.ufv.br//bitstream/123456789/3860/3/texto%20completo.pdf.jpgaef9b8ec87cb6d4959f190682ab25b24MD53123456789/38602017-04-20 09:56:01.961oai:locus.ufv.br:123456789/3860Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452017-04-20T12:56:01LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
