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.

This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a tribute to three outstanding scientists, Professors Jan Anderson FRS, Leslie Dutton FRS and John Walker FRS, Nobel Laureate. Covering some of the most recent advances in the fields of Bioenergetics and Photosynthesis, this book is a compilation of contributions from leading scientists actively involved in understanding the natural biological processes associated with the flow of energy in biological cells. The lectures found in this significant volume were presented at a meeting in March 2016 in Singapore to commemorate the outstanding research in this area.The contents begin with the ideas, specially the contribution from Nobel Laureate Rudolph Marcus, who is well-known for creating the theory of electron transport reactions. This is followed by contributions of many others on various aspects of respiratory and photosynthetic transport chains as well as the dynamic regulation of light harvesting and electron transport events in oxygenic photosynthesis. The book is highly recommended to postgraduate students and researchers who are interested in various aspects of bioenergetic cycles.

Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and gen eral nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the mil ligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques fmd their way into the classroom when the problems involved have been suffici ently ironed out to permit students to master the manipulations in a few labo ratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which might be applicable for use in biology laboratory courses.

Available in PDF, EPUB and Kindle. Book excerpt: True bugs (Heteroptera) are a diverse and complex group of plant-feeding and predatory insects important to food production, human health, the global economy and the environment. Within the nearly 43,000 species described around the world, Neotropical true bugs are particularly diverse, and much remains to be discovered about their biology and relations with other species. Inspired by the need for a comprehensive assessment, True Bugs (Heteroptera) of the Neotropics is the most complete and thorough review ever published. Experts in each of the seven infraorders have drawn together the scattered literature to provide detailed treatments of each major taxon. The most common and important species as well as select lesser known species in each major family are covered, highlighting morphology, classification, biology and ecology. The numerous color illustrations highlight key species and their adaptations, and importance to basic and applied sciences is discussed. Each chapter is based on an up-to-date review of the literature, and with a bibliography of more than 3,000 references, readers are presented with an unprecedented and vital and timely account of the true bugs of the Neotropical Region.

It also presents possible technologies to be applied in field crops for pest management that could be developed as the basis of the interplay of stink bug communication signals.
