This book was released on 1989 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A pesquisa foi desenvolvida em Maracanan, Ceara, Brasil, objetivando a identificacao de fontes de resistencia a lagarta do cartucho, Spodoptera frugiperda (J.E. Smith, (lep., Noctuidae), em dez genotipos de milho, Zea mays L., e a avaliacao do efeito desses insetos na produtividade do milho, relacionando-se, ademais, alguns caracteres agronomicos da planta e da espiga com os danos cometidos a graminea pelas referidas pragas. Os genotipos de milho foram: Centralmex, Dentado Composto, Flint Composto, CMS 04, Amarillo del Bajio, Azteca. BA-II-Cristal, Crioulo de Roraima, PE-I-Moroti e CE-I-Cateto. Para o estudo da interacao planta (genotipos/pragas, aproveitou-se da infestacao natural destas e, concernente a Spodoptera frugiperda, os danos avaliados em funcao do estado sanitário do cartucho e da folha mais nova com colar visível, segundo uma escala visual de notas, variando de 1 a 5, nas fases 1, 2 e 3 do ciclo biológicos da cultura do milho. A mensuracao dos danos causados por Helicoverpa zea as espigas foi procedida por meio de uma escala contimetrica de notas, baseada na ocorrencia ou nao de areas desprovidas de graos. Os graus de infestacao de lagartas de S. frugiperda e H. zea foram correlacionados com a altura da planta, altura da espiga, comprimento da espiga, diametro da espiga, numero de folhas e produtividade. Alguns resultados revelaram que os genotipos Dentado Composto, Centralmex, CMS 04, Flint Composto e Azteca superaram os demais em produtividade, nao se correlacionando, porem, este parametro (...).

This book was released on 2001 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Os objetivos deste trabalho se concentraram na avaliação de novas fontes de germoplasma para resistência à lagarta do cartucho (Spodoptera frugiperda, Smith, 1797, Lepidoptera: Noctuidae), praga chave da cultura de milho no Brasil. Foi utilizado um esquema dialélico parcial entre 20 populações representantes de germoplasma brasileiro e 9 populações exóticas e semi/exóticas de diferentes origens. Os 180 híbridos e as 29 variedades genitoras, junto com duas testemunhas comerciais, foram avaliados em três locais no Estado de São Paulo (Brasil). Foram considerados os caracteres resistência à lagarta do cartucho (RLC), sob infestações artificiais e naturais, produtividade de grãos (PG) e altura de planta (AP). As populações CMS14C e MIRT, e o híbrido São José x MIRT apresentaram a maior resistência, com valores de 1,8; 1,7 e 1,4, respectivamente. As populações PMI9401 e PR91B, e o híbrido CMS14C x B97. Ituiutaba tiveram a maior produtividade, com 4893, 3858 e 5677 kg/ha, respectivamente. Os valores de heterose foram de -28% a 47% para RLC e de -21% a 125% para PG, com valores médios de -0,43% e 31%, respectivamente. O caráter RLC não apresentou interação genótipo 'versus' ambiente significativa. Foram detectados efeitos genéticos aditivos e não aditivos que indicaram a viabilidade da implementação de programas de seleção recorrente intra ou interpopulacional para este caráter. Se encontraram efeitos genéticos aditivos e não aditivos p.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to address the importance of natural enemies and functional diversity for biological control in Neotropical agroecosystems. Several aspects related to the conservation of natural enemies, such as vegetation design and climate change, are discussed in Part 1 and the bioecology of several insects groups used in biological control in Latin America is presented in Part 2. Part 3 is devoted to mass production of natural enemies while Part 4 describes how these insects have been used to control of pests in major crops, forests, pasture, weeds and plant diseases. Lastly, Part 5 reports Latin-American experiences of integration of biological in pest management programs.

Download or read book Biodiversity and Pest Management in Agroecosystems written by Miguel Altieri and published by CRC Press. This book was released on 2018-10-03 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

Book Synopsis Enhancing Biological Control by : Charles Hammond Pickett
Download or read book Enhancing Biological Control written by Charles Hammond Pickett and published by Univ of California Press. This book was released on 1998 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past ten years an increasing number of field entomologists and farmers have recognized that conservation of natural enemies is important to effective biological control in many agricultural systems. This collection addresses an important gap in the biological control literature by providing the first comprehensive summary of recent findings on habitat manipulation to control pests. Enhancing Biological Control includes contributions from experts around the world: the United States, Finland, Germany, Great Britain, People's Republic of China, and Switzerland. Chapters cover habitat modification in such areas as fields, orchards, or vineyards, and along or near the perimeters of fields, including hedges or other uncultivated areas. Generalist and specialist natural enemies are described in full, as are theoretical and practical issues. Experimental designs for studying enhancement come into play, and the editors include a modeling study that explores how the dispersal of natural enemies interacts with the positioning of refuges. This volume is an invaluable source of information to researchers, progressive farmers, and agricultural consultants.
