Book excerpt: A mandioca (Manihot esculenta crantz) é uma das culturas mais importantes como fonte de energia para milhões de pessoas que vivem nas regiões tropicais e subtropicais do mundo, apesar de ser cultivada basicamente por pequenos produtores que utilizam pouca tecnologia. Nos ultimos anos varias organizações internacionais como CIAT (Colômbia). IITA (Nigéria), CATIE (Costa Rica) e programas nacionais de pesquisa na América Latina (ex.: Colombia, Brasil, Cuba), Africa (ex.: Camarões, Nigéria, Uganda) e Ásia (ex.; Índia, Indonésia, China, Tailandia) tem realizado pesquisas sobre a mandioca e o complexo de pragas associadas. Inumeros são os fatores que influenciam na produção da mandioca e, entre eles, as pragas podem acarretar grandes reduções. Trata-se de uma cultura que abriga um grande complexo de insetos e ácaros, sendo que muitas destas espécies são consideradas pragas de menor importância, ocasionando pouca ou nenhuma perda no rendimento, enquanto outras espécies podem causar danos econômicos consideráveis. Em função das características socio-econômicas da cultura e seu período vegetativo longo, a aplicação continua de inseticidas para controlar as pragas torna-se bastanteonerosa, razão pela qual o controle químico e uma prática que raramente se justifica economicamente.

Book excerpt: A cultura da mandioca vem recebendo, nos ultimos anos, grande atencao das instituicoes de pesquisa, devido ao potencial que oferece como materia-prima para a producao de alcool. Com o advento do Programa Nacional do Alcool, grande areas tem sido plantadas com essa cultura, cujo procedimento favorece em muito a proliferacao de pragas. A media da produtividade nacional, 12 t/ha, e muito baixa, devido, principalmente, acondicao de cultura familiar e minifundiaria, e das oscilacoes continuas de precos. os resultados de pesquisa relatam que se pode alcancar ate 40 t/ha (Centro Nacional de Pesquisa de Mandioca e Fruticultura - CNPMF) ou 70 t/ha (Centro Internacional de Agricultura Tropical - CIAT), desde que se observem as praticas culturais necessarias. As pragas da mandioca incluem uma grande diversidade de artropodos. Muitas das especies identificadas sao consideradas pragas de menor importancia e ocasionam pouca ou nenhuma perda no rendimento. As pragas podem causar dano a mandioca atraves da reducao da area fotossinteticamente ativa, resultando em decrescimos no rendimento; atraves do ataque as hastes, debilitando a planta e inibindo o transporte de nutrientes; atraves do ataque ao material de plantio, reduzindo a germinacao; e, podem atacartambem as raizes, ocasionando podridoes secundarias. Alguns insetos sao vetores e disseminadores de doencas.

Book excerpt: Inumeros sao os fatores que influenciam na producao da mandioca e, entre eles, as pragas podem acarretar grandes reducoes. Esta cultura abriga um grande complexo de insetos e acaros, sendo que muitas destas especies sao consideradas pragas de menor importancia, ocasionando pouca ou nenhuma perda no rendimento, enquanto outras especies podem causar danos economicos consideraveis, sendo, portanto, consideradas pragas de maior importancia. Em funcao das caracteristicas socio-economicas da cultura e seu periodo vegetativo longo, a aplicacao continua de inseticidas para controlar as pragas torna-se bastante onerosa, razao pela qual o controle quimico e uma pratica que raramente se justifica economicamente. Observacoea indicam que as pragas que atacam a planta durante um periodo prolongado, tais como acaros, percevejo de renda, mosca branca e cochonilha farinhosa, reduzem o rendimento em maior grau que aquelas que causam desfolhamento e outros danos durante um periodo curto, como o mandorova, masca do broto, mosca da fruta e formiga cortadora de folhas. Isto deve-se a capacidade da planta de mandioca em recuperar-se de um dano causado em curto tempo, sob condicoes ambientais favoraveis.

Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho foi conduzido em 60 pequenas/medias propriedades, na regiao de Ouricuri, PE. As culturas estudadas e as princpais pragas a elas associadas foram feijao-macassar: Elasmopalpus lignosellus (Zeller), Empoasca Kraemeri Ross Moore e Chalcodermus sp.; milho: E. lignosellus e Spodoptera frugiperda (J.E. Smith); algodao moco: Alabama argillacea (Huebn.) e, provavelmente, Oxycarenus hyalinipennis (Costa); mamona: Emposca sp.; mandioca: Mononychellus tanajoa (Bondar) e Vatiga illudens (Drake). Aproximadamente 15% dos agricultores consideram natural que ambos, agricultores e insetos, compartilhem da producao das plantas. Nenhum agricultor faz qualquer tipo de controle cultural. Em nenhum caso, o agricultor atribui sua preferencia por uma ou outra variedade a maior resistencia ao ataque de pragas. Nenhum agricultor conhece qualquer inseto predador ou parasito. Cinco por cento dos agricultores consultados usam esporadicamente o controle quimico. Tambe, 5% dos agricultores ja se intoxicaram com defensivos agricolas.

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.

Book Synopsis The Root Causes of Biodiversity Loss by : Alexander Wood
Download or read book The Root Causes of Biodiversity Loss written by Alexander Wood and published by Routledge. This book was released on 2013-11-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.

Available in PDF, EPUB and Kindle. Book excerpt: Mites (Acari) for Pest Control is an extremely comprehensivepublication, covering in depth the 34 acarine families that containmites useful for the control of pest mites and insects, nematodesand weeds. In addition to providing information on each relevantacarine family, the book includes essential information on theintroduction, culture and establishment of acarine biocontrolagents, the effects of the host plants, agrochemicals andenvironmental factors on mites used in biological control anddiscusses commercial and economic considerations in theiruse. Mites are now used in various ways for biological control, witha growing number of species being sold commercially throughout theworld. The authors of this landmark publication, who have betweenthem a huge wealth of experience working with mites in biologicalcontrol programs, have put together a book that will for many yearsbe the standard reference on the subject. The book will be of great value to all those working in cropprotection and biological control both in research as well as incommercial operations, including acarologists, entomologists,integrated pest management specialists, agricultural and plantscientists. Libraries in all universities and researchestablishments where these subjects are studied and taught shouldall have copies on their shelves.
