Book excerpt: The present PhD study investigates the aspect of chemical ecology in the European corn borer (ECB, Ostrinia nubilalis Hübner, Lepidoptera: Crambidae): pherotypes reproductive isolation and host plant specialisation.All the experiences were designed to have ecologically relevant information about the chemical signals released or perceived by ECB moth during the reproduction period. Most of the work was conducted close to natural conditions and taking into account all the behavioural traits of ECB.First we investigated what can be the chemical landscape of maize field for host-seeking ECB moth. The whole volatile blends that make up the olfactory environment of maize field biotope was identified according to the ECB oviposition behaviour (Paper I). Secondly taking into account the diel periodicity of ECB behaviour we studied the diel changes of volatile profiles released from maize plant and from maize field (Paper II). Thirdly, we studied the process of host fidelity within the ECB host plants. The volatiles released from different host plants at the time of ECB oviposition flight were identified and the oviposition behaviour was studied in wind tunnel to evidence the host plant preferences of ovipositing females (Paper III). Fourthly, we address the question on assortative mating in ECB pherotypes and we investigated the chemical signals involved in the reproductive isolation in ECB pherotypes. We focused on the male pheromone produced by hairpencils and on courtship behaviour (Paper IV).

Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book Pheromone Communication in Moths written by Jeremy D. Allison and published by Univ of California Press. This book was released on 2016-10-25 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Ê Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. ÊÊ Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.

Download or read book Insect Resistance Management written by David W. Onstad and published by Academic Press. This book was released on 2013-10-08 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. Provides insights from the history of insect resistance management (IRM) to the latest science Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions

Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.
