This book was released on 2013-11-11 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest Management Programs for Deciduous Tree Fruits and Nuts attempts to present the current status of pest management programs in orchard ecosystems. The book is a collection of papers from a symposium convened on the subject for the 1977 National Meeting of the Entomological Society of America and invitational papers on commodities not covered during the symposium. In recent years, books have appeared on "integrated pest management (IPM)"; however, most of these have concentrated on field crop IPM with an occasional chapter on fruits. No publication presently exists which brings together information on the pest management programs currently being conducted on the major nut crops, almonds, pecans and walnuts. Because it is the first treatment for almonds and walnuts, the authors of these chapters have attempted not only to present the current IPM technology but the historical data which led to the contemporary programs. Two chapters appear on pecan IPM. The first concentrates on the development of a management program for the pecan weevil, the key arthropod pest of pecans, while the second discusses the implementation of pilot pecan IPM programs in two southeastern states. The latter chapter illustrates that even with a limited data bank, the pesticide load in pecan orchards can be reduced by the adoption of the IPM approach to pest control.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The integrated mite management (IMM) program in Washington has depended on the biological control of spider mites provided by Galendromus occidentalis (Nesbitt). We explored methods of improving this program. A series of inundative releases of G. occidentalis was performed in commercial apple orchards. None of the releases increased G. occidentalis numbers or reduced pest spider mite populations. It was concluded that a cost prohibitive number of predators would be necessary to maintain pest mites below economic thresholds, emphasizing the importance of conservation biological control. Phytoseiids in apple orchards across Washington were sampled to determine diversity and elucidate factors affecting abundances. While the community was expected to be completely dominated by G. occidentalis, Amblydromella caudiglans (Schuester) was also highly abundant. G. occidentalis abundance was positively affected by conventional pesticide regimes and bifenazate use, whereas A. caudiglans was negatively affected by bifenazate and positively affected by herbicide strip weediness. This indicated that A. caudiglans was more susceptible to disruptive pesticide inputs than G. occidentalis . This was confirmed by an assay wherein several orchard pesticides caused higher mortality of A. caudiglans than G. occidentalis. The recent phase out of certain orchard pesticides may have allowed A. caudiglans to become more common. To understand the mite species complex in the absence of pesticides, an insecticide-free research orchard was monitored at regular intervals during two growing seasons. Generalist phytoseiids were more common than G. occidentalis throughout both seasons. These species were nearly dependent on Aculus schlechtendali (Nalepa) as a food source, as spider mites remained scarce. This emphasizes the role of spider mites as induced pests and suggests that in the absence of pesticide applications, a complement of generalist predators is capable of maintaining spider mite populations at very low densities. G. occidentalis was also found to be less affected by leaf surfaces than generalist phytoseiids examined in previous studies. These findings indicate that G. occidentalis is biological different from the generalist phytoseiids that may replace it as pesticide use changes. Therefore, IMM must constantly be re-evaluated in order to meet orchardists' needs.

Download or read book Conservation Biological Control written by Pedro A. Barbosa and published by Elsevier. This book was released on 1998-06-26 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a comprehensive treatment of how the principles of ecology and conservation biology can be used to maximize biological control. Conservation Biological Control presents various means to modify or manipulate the environment to enhance the activities of natural enemies of pests. It establishes a conceptual link between ecology and the agricultural use of agents for biological control, and discusses both theoretical issues as well as practical management concerns. Certain to be interesting to ecologists and entomologists, this volume will also appeal to scientists, faculty, researchers and students interested in pest management, horticulture, plant sciences, and agriculture. - Contains chapters by an international team of leading authorities - Establishes a conceptual link between ecology and the agricultural use of agents for biological control - Discusses both theoretical issues as well as practical management concerns - Provides specific examples of how conservation principles are used to maximize the biological control of pests
