Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Soybean Insect Pests is the first book in a new series from the Entomological Society of America that examines pest management from all angles—magnifying practical field strategies for growers—and updates growers on the latest protection techniques—preventing needless crop loss as a result of outdated pest control procedures. Edited by Leon G. Higley and David J. Boethel, this book outlines fundamental approaches to soybean pest management that can aid in reducing crop damage and loss. It provides detailed descriptions of topics such as insect identification, life-history data, and management options. This comprehensive guide includes discussions on soybean ecology and physiology, soybean insect pests, predators and parasitoids, soybean pest management procedures, noninsect soybean pests, and insect management. Also included are 92 color photographs, 200 illustrations, a directory of resources for obtaining local information, and a glossary.

Available in PDF, EPUB and Kindle. Book excerpt: Based on a symposium sponsored by the Board on Agriculture, this comprehensive book explores the problem of pesticide resistance; suggests new approaches to monitor, control, or prevent resistance; and identifies the changes in public policy necessary to protect crops and human health from the ravages of pests. The volume synthesizes the most recent information from a wide range of disciplines, including entomology, genetics, plant pathology, biochemistry, economics, and public policy. It also suggests research avenues that would indicate how to counter future problems. A glossary provides the reader with additional guidance.

Book excerpt: Abstract: Since its introduction in 2000 to North America, the soybean aphid (Aphis glycines) has spread across much of the U.S. and Canadian soybean growing regions, and has become one of the most damaging insect pests of this crop. Such rapid and large-scale pattern suggests that A. glycines has high rates of adaptability and dispersal. These trends have been linked to the effect of host transition, and the ability of aphid populations to clone and migrate across soybean fields during summer. The soybean aphid is a holocyclic insect that alternates between two hosts: (1) buckthorn, where sexual reproduction, oviposition and overwintering occur; and (2) soybean, where clonal reproduction and large-scale migration occur. We conducted a study using eight North American locations where aphids were collected twice, early and late in the soybean season. To analyze the genetic structure of the sampled populations, we used six microsatellite markers, and developed and validated twenty-four Single Nucleotide Polymorphic markers. These markers are, to my knowledge, the first SNPs to be validated for soybean aphid. The objective for the study was to analyze the genetic structure of soybean aphid populations during the transition from buckthorn to soybean in spring, and the progressive changes in the genetics of these populations after clonal reproduction and migration. The hypotheses from the study were that (1) soybean aphids go through population bottlenecks that differentiate population at the beginning of the season, and (2) there is a large-scale dispersion of aphids across soybean fields once the aphids have reached a population outbreak. Results from the study showed strong population differentiation among early populations and supported the hypothesis of large-scale dispersal among late populations, demonstrating that indeed there is a continuous change in the genetic structure of the soybean aphid explained through the migratory behavior of the aphids. Future studies are needed to understand the effect of host abundance and distribution in the genetic composition of soybean aphid populations, as well as to track the genetic diversity of soybean aphid over years without outbreaks.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscape complexity and arthropod predators have been shown to play a major role in suppression of the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) in North America. I examined the impact of landscape complexity and patterns of predator movement between habitats on sentinel soybean aphid populations in 27 soybean fields in Manitoba over a two-year period. Predator movement was quantified using bi-directional Malaise traps and mark-release-recapture experiments. My results revealed that there was a strong to moderate suppression of soybean aphids across the gradient of landscape complexity studied. I found that predator movement between soybean and adjacent habitats was as important as landscape characteristics in explaining aphid suppression. My results indicate that the direction of predator movement in soybean field borders is influenced by the type of adjacent habitat and by predator identity. My findings highlight the importance of pest control services provided by aphidophagous predators in agricultural landscapes.

Available in PDF, EPUB and Kindle. Book excerpt: The Georgia Pest Management Handbook provides current information on selection, application, and safe use of pest control chemicals. This handbook has recommendations for pest control around homes and on pets; for pests of home garden vegetables, fruits, and ornamentals; and for pests of public health interest associated with our homes. Cultural, biological, physical, and other types of control are recommended where appropriate. Pesticide recommendations are based on information on the manufacturer labels and on performance data from research and extension trials at the University of Georgia and its sister institutions. Because environmental conditions, the severity of pest pressure, and methods of application vary widely, recommendations do not imply that performance of pesticides will always be acceptable. This publication is intended to be used only as a guide. Trade and brand names are used only for information. The University of Georgia does not guarantee nor warrant published standards on any product mentioned; nor does the use of a trade or brand name imply approval of any product to the exclusion of others that may also be suitable. Always follow the use instructions and precautions on the pesticide label. For questions, concerns, or improvement suggestions regarding the Georgia Pest Management Handbook, please contact your county agent.
