Genetic engineering suggests new avenues for constructing useful products, but it also poses hazards to the health of the environment and the public. Delineating those hazards is complicated, difficult, and important at every level of risk assessment and risk management decision-making. Risk assessment and risk management may be further complicated by the need to discover more detailed information than is usually available.Genetically Engineered Organisms: Assessing Environmental and Human Health Effects gives credence to good science and to the notion that we do not have to argue about the ecological and human health effects of genetic engineering. Instead, it supports the position that we can undertake the painstaking science necessary to identify and understand those effects.Written by researchers who have done cutting edge research in disciplines such as botany, entomology, plant pathology, and other agricultural and environmental sciences, this book elaborates critical research on pollen movement, spread of transgenes in natural communities, fitness effects, resistance development, and unpredicted impacts on target and non-target organisms. These topics are explored in contexts ranging from Bt corn events and viral resistant oats to transgenic salmon and altered malarial vectors. Many chapters address theoretical and informational gaps that research presents to questions of biosafety, and some offer historical insights into factors that may affect risk assessment and risk management decision-making at the community, national, and international levels.

Presents the first efforts to explore ecological interactions between insects and plants across several trophic levels, with special focus on mediation of complex interactions by plant allelochemicals. First section looks at effects of plant allelochemicals on predator-prey and host-parasitoid interactions. Second section reveals the role of microorganisms as mediators of interactions between insects and plants. Third section unifies and extends current theory to examine the effects of allelochemicals on the second and third trophic levels. Final section traces the physiological effects of plant allelochemicals in animal behavior, population regulation, maintenance of mimicry systems, and evolution of host range.

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.
