Book excerpt: Excerpt from Integrated Pest Management Research Symposium: The Proceedings; August 1985 Sample unit shape, as well as size, is an important factor to consider when sampling I 0 egg galleries (fig. 2, table The 5 x 20 cm samples have ca. Half the standard deviation as cm samples while the lox 10 cm samples fall in between. The cm (25 cm2) sample unit is just as good as the 20 X5 cm (100 cm?) sample unit even though the latter has four times the bark area. The orientation of the 10 cm sample so that it cuts across more of the vertical egg gallery systems reduces the number of zero counts and the standard deviation. Size of the sample unit still has an effect, but only when com pared between samples of similar shape. Regression equations of sample variance versus mean density can be used to calculate the number of samples needed to estimate I 0 population densities at any desired precision and confidence level. The equation for calculating sample size n is. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Biological Control in Agricultural IPM Systems covers the proceedings of the 1984 symposium on Biological Control in Agricultural IPM Systems, held in the Citrus Research and Education Center of the University of Florida at Lake Alfred. The symposium summarizes the status and practical use of biological control in agricultural integrated pest management (IPM) systems in the United States. The book is organized into seven parts encompassing 31 chapters that cover the biological control of arthropods, weeds, plant pathogens, and nematodes. After briefly discussing the status and issues of biological control in IPM, the book deals with the basic principles of IPM programs and their related costs, risks, and benefits in biological control. The text also describes the compatibility of plant resistance with biological control of arthropods and the chemical mediated host or prey selection behaviors of entomophagous insects attacking herbivorous insect pests. It explains the development of microbial insecticides; the genetic improvement of insect pathogens; the use of entomogenous nematodes in cryptic and soil habitats; and the techniques for integrating the influences of natural enemies into models of crop/pest systems. The fourth part of the book focuses on the biological control of weeds. The following part considers the general concepts relating to the unique characteristics of plant diseases affecting aerial plant parts. This part also examines the biological control of soil plant pathogens in IPM systems and the use of soilborne viruses, bacteriocins, and hypovirulent strains of fungi as biological control agents. The concluding parts describe the biological control of nematodes and the status and limits to biological control in selected commodity IPM systems, such as citrus, grapes, alfalfa, cotton, and soybean. Entomologists, plant pathologists, weed scientists, nematologists, toxicologists, and economists will find this book invaluable.
