Available in PDF, EPUB and Kindle. Book excerpt: Transgenic, insecticidal corn hybrids (Bt corn) are a tactic for managing European corn borer, Ostrinia nubilalis (Hübner), in North America. To slow development of Bt-com resistance, an Insect Resistance Management plan requires monitoring and nearby refugia. We examined the effect of feeding diet incorporated with Cry1Ab on growth, development, and survival of Nosema-infected and uninfected O. nubilalis. Increasing concentrations of Cry1Ab in diet reduced larval growth and development rates, and this phenomenon was amplified by microsporidiosis. This work demonstrates that it is important to determine whether pathogens are present when monitoring resistance. Pheromone-baited traps are used in O. nubilalis studies. However, differences in captures may be confounded by design, location relative to a windbreak, and changes in local weather. We examined differences in captures among wing traps, bucket/funnel traps, Hartstack wire-mesh cone traps, as well as among three cone trap designs. Second, we examined the influence of cone-trap location relative to windbreaks on numbers of moths captured. Third, we examined the relationship between nightly mean air temperature, relative humidity, wind speed, precipitation, and numbers of moths captured in cone traps. Numbers of moths captured was significantly influenced by trap design, with cone traps capturing the most moths. Under strong or moderate wind speeds, traps located leeward of windbreaks captured the most moths, but when wind speeds were light, traps not associated with windbreaks captured the most moths. Changes in numbers of moths captured on a given night were related weakly to weather. Air temperature parameters were consistently most influential in the regression models, and their relationship with moth captures was positive. Determining the appropriate distance between refugia and Bt corn, and development of mitigation-remediation strategies, requires knowledge of adult dispersal and mating behavior. We examined influences of pheromone lure, plant density, and plant species on distributions of feral and newly-emerged, laboratory-reared O. nubilalis among small-grain aggregation plots. The majority of adults did not colonize aggregation plots, suggesting that recently-eclosed adults leave their natal field and do not colonize the first aggregation sites encountered. Mass releases of laboratory-reared pupae in the field may not be a viable resistance-remediation tactic.
Download or read book Dispersal Behavior of Neonate European Corn Borer Ostrinia Nubilalis on Transgenic Bt Corn written by Jessica Ann Goldstein and published by ProQuest. This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Lepidoptera disperse as adults, but in some groups the larvae disperse as well. Larval dispersal takes the form of ballooning; larvae use silk to hang off of plant surfaces and some get picked up by the wind. The longer the silk length, the greater the drag and the more likely the larva is to get picked up by the wind and the farther the larva will travel. The European corn borer (ECB), Ostrinia nubilalis, has been observed ballooning and is currently the target of a large control effort using transgenic Bt corn. I examined the differences between ECB larval dispersal on Pioneer 34K78 Mon 810 event Bt corn and Pioneer 34K77 non-Bt isoline corn. I tested plant abandonment, larval dispersal in artificial plots and ECB silking behavior. My results suggest that ECB larvae that hatch on a Bt corn plant abandon that plant with a higher frequency than ECB larvae that hatch on a non Bt corn plant and that ECB larvae are capable of reaching neighboring corn plants by ballooning. This dispersal behavior may play a significant role in resistance management, particularly in the spacing of non-Bt refuges. These experiments help us to better understand ECB neonate behavior and may apply to other insects under Bt selection pressure.

Download or read book Insect Outbreaks Revisited written by Pedro Barbosa and published by John Wiley & Sons. This book was released on 2012-06-29 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

Download or read book Genetic Structure and Local Adaptation in Natural Insect Populations written by Susan Mopper and published by Springer. This book was released on 2013-03-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing an essential foundation for evolutionary theory, this comprehensive volume examines patterns of genetic variation within natural insect populations, and explores the underlying mechanisms that lead to the genetic divergence of coexisting organisms. In particular, the text investigates current research on finescale genetic structure in natural insect populations. Internationally renowned scientists offer a wealth of current information not previously published. Part I present case studies of adaptive genetic structure in natural insect populations, including a critical discussion of the strenghts and weaknesses of the experimental methods employed. Part II addresses the ecological mechanisms that produce adaptive genetic structure in natural insect populations. Part III describes how behavioral and life-history patterns influence genetic structure. Finally, Part IV combines theoretical and empirical approaches linking genetic structure at the population level with larger-scale patterns of variation, such as host race formation and speciation. This broad-ranging, interdisciplinary source of information supplies a thorough examination of the mechanisms that promote and impede genetic structure in natural insect populations. It is a book that will be of interest to undergraduate and graduate students, and to researchers in the fields of ecology, evolution, insect and plant systems, entomology, and population genetics.
