Resumo: | The Chinese cabbage (Brassica chinensis L.) has been indicated, along with other vegetables, as an excellent alternative for Brazilian agribusiness, especially those grown in organic production system. Regarding to insect pests, that damage this crop, it shows the chrysomelid Microtheca semilaevis Stal, which cause defoliation on plants during larval and adult stages. Thus, the present work was developed to study bioecology aspects of M. semilaevis, obtaining information about biology, food preference and consumption, natural enemies and population fluctuation. In laboratory and under controlled conditions, biological aspects, such as duration, feasibility and measurement of the immature and adults; and fertility and longevity of adults were evaluated to determine fertility life table. Also in laboratory, experiments to evaluate food consumption and feeding preference of these beetles were conducted fed on leaf discs of four host varieties: Chinese cabbage, watercress (Nasturtium officinale L.), arugula (Eruca sativa L.) and mustard (Brassica juncea C.). Under field conditions, samples of natural enemies of the different development stages were taken in cultivation, besides studying the population dynamics of Microtheca spp. during Chinese cabbage crop cycle in Santa Maria, RS. The eggs have an average incubation period of 6.13 ± 0.04 days and average survival rate of 76.00%. M. semilaevis presents four larval instars, and the average duration of each instar were 2.86 ± 0.06, 1.97 ± 0.05, 1.80 ± 0.06 and 2.43 ± 0.07 days. The cycle from egg to adult is approximately 22 days. Life table fertility determined an increasing capacity of 166 times in each generation, and the average length of a generation of 49 days and finite rate of increase of 1.116 individuals / week. Larvae prefer watercress among crucifers tested, while adults prefer watercress and arugula, with lower consumption for both development stages ranging from Chinese cabbage and mustard. The peak population of larvae and adults in the field occurred in October. There was no emergence of parasitoids on larval and adult stages. However, predators were found belonging to four families with a predominance of Coccinellidae and Pentatomidae and also Vespidae and Reduviidae were found in smaller numbers. The results in this work provide subsidies that might be used for the establishment of integrated management strategies for M. semilaevis. |

Com relação aos insetos-praga que danificam a cultura, destaca-se o crisomelídeo Microtheca semilaevis Stal, causando desfolhamento nas plantas durante as fases larvais e adulta. Assim, o presente trabalho teve como objetivo estudar aspectos bioecologicos de M. semilaevis, obtendo informações sobre biologia, preferência e consumo alimentar, inimigos naturais e flutuação populacional. Em laboratório e sob condições controladas, foram avaliados aspectos biológicos, como a duração, a viabilidade e a medição de imaturos e adultos; também, a fecundidade e a longevidade dos adultos, para permitir a elaboração da tabela de vida de fertilidade. Ainda em laboratório, experimentos avaliaram o consumo e a preferência alimentar desses coleópteros alimentados com discos foliares de quatro variedades hospedeiras: couvechinesa, agrião (Nasturtium officinale L.), rúcula (Eruca sativa L.) e mostarda (Brassica juncea C.). Em condições de campo, foram realizadas coletas em cultivo dos inimigos naturais das diferentes fases de desenvolvimento, além de estudar a flutuação populacional de Microtheca spp. no ciclo da cultura de couve-chinesa em Santa Maria, RS. Os ovos apresentam um período de incubação médio de 6,13±0,04 dias e viabilidade média de 76,00%. M. semilaevis apresenta a fase larval com quatro instares, sendo que a duração média de cada ínstar foi de 2,86±0,06; 1,97±0,05; 1,80±0,06 e 2,43±0,07 dias. O ciclo de ovo a adulto foi de, aproximadamente, 22 dias. Através da tabela de vida de fertilidade determinou-se uma capacidade de aumento de 166 vezes a cada geração, sendo a duração média de uma geração de 49 dias e a razão finita de aumento de 1,116 indivíduos/semana. Larvas preferem agrião dentre as brássicas testadas, sendo que adultos preferem agrião e rúcula, com menor consumo, para ambas as fases de desenvolvimento, variando entre couve-chinesa e mostarda. Os picos populacionais de larvas e adultos, no campo, ocorreram no mês de outubro. Não houve emergência de parasitoides nas fases larval e adulta. Porém, foram encontrados predadores pertencentes a quatro famílias com predomínio de Coccinellidae e Pentatomidae, sendo Vespidae e Reduviidae presentes em menor número. Os resultados encontrados no presente trabalho fornecem subsídios que podem ser utilizados para o estabelecimento de estratégias de manejo integrado de M. semilaevis.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgrobiologiaUFSMBRCiências BiológicasCouve-chinesaBiologiaInimigos naturaisFlutuação populacionalCoccinellidaePentatomidaeChinese cabbageBiologyPopulation fluctuationCoccinellidaePentatomidaeNatural enemiesCNPQ::CIENCIAS BIOLOGICASBioecologia de Microtheca semilaevis Stal, 1860 (Col.: Chrysomelidae)Bioecology of Microtheca semilaevis Stal, 1860 (Col.: Chrysomelidae)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisDequech, Sônia Thereza Bastoshttp://lattes.cnpq.br/9468394500778495Morais, Rosana Matos dehttp://lattes.cnpq.br/6560593368696873Morais, Ana Beatriz Barros dehttp://lattes.cnpq.br/3951242416159088http://lattes.cnpq.br/7718576444161511Fornari, Rodrigo2000000000064003003003003006fb2bd70-c492-4978-823b-4f9bb71bb490cc1d7fb1-179c-416d-8c66-3a951b4d68b2e60b7ae2-a502-42d0-b55c-a2641f4f8a313182b727-9913-4202-a0dc-9373ad115d4dinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFORNARI, RODRIGO ARTINI.pdfapplication/pdf795894http://repositorio.ufsm.br/bitstream/1/4856/1/FORNARI%2c%20RODRIGO%20ARTINI.pdf0b47c2a606c6e697ef010b8182fea16bMD51TEXTFORNARI, RODRIGO ARTINI.pdf.txtFORNARI, RODRIGO ARTINI.pdf.txtExtracted texttext/plain93035http://repositorio.ufsm.br/bitstream/1/4856/2/FORNARI%2c%20RODRIGO%20ARTINI.pdf.txtfc4886014a39d30ea474c0d5d523e199MD52THUMBNAILFORNARI, RODRIGO ARTINI.pdf.jpgFORNARI, RODRIGO ARTINI.pdf.jpgIM Thumbnailimage/jpeg4970http://repositorio.ufsm.br/bitstream/1/4856/3/FORNARI%2c%20RODRIGO%20ARTINI.pdf.jpg09bcb40e7d896401ed9575615aed496aMD531/48562022-05-11 11:00:25.347oai:repositorio.ufsm.br:1/4856Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-05-11T14:00:25Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |

Also in laboratory, experiments to evaluate food consumption and feeding preference of these beetles were conducted fed on leaf discs of four host varieties: Chinese cabbage, watercress (Nasturtium officinale L.), arugula (Eruca sativa L.) and mustard (Brassica juncea C.). Under field conditions, samples of natural enemies of the different development stages were taken in cultivation, besides studying the population dynamics of Microtheca spp. during Chinese cabbage crop cycle in Santa Maria, RS. The eggs have an average incubation period of 6.13 ± 0.04 days and average survival rate of 76.00%. M. semilaevis presents four larval instars, and the average duration of each instar were 2.86 ± 0.06, 1.97 ± 0.05, 1.80 ± 0.06 and 2.43 ± 0.07 days. The cycle from egg to adult is approximately 22 days. Life table fertility determined an increasing capacity of 166 times in each generation, and the average length of a generation of 49 days and finite rate of increase of 1.116 individuals / week. Larvae prefer watercress among crucifers tested, while adults prefer watercress and arugula, with lower consumption for both development stages ranging from Chinese cabbage and mustard.
