Download or read book Insects of Alfalfa in Manitoba with Particular Reference to Lygus Spp Adelphocoris Lineolatus Hemiptera Miridae and Acyrthosiphon Pisum Homoptera Aphididae and Their Natural Enemies written by Md. Jashim Uddin and published by . This book was released on 2005 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was conducted from 1999 to 2001 to determine the most suitable method to be used for sampling insect pests on alfalfa, to determine the seasonal occurrence of common insect pests and natural enemies, to assess the roles of common natural enemies on insect pests, and to find out ways to increase the benefits from insect natural enemies in relation to the production practices of alfalfa in Manitoba. Among different sampling methods, sweep-net sampling was found to be the most consistent and reliable method of sampling most insect taxa, although beat tray sampling provided better estimates for Lygus spp. nymphs. It was found in the present study that Lygus spp. Hahn, Adelphocoris lineolatus (Goeze) and Acyrthosiphon pisum (Harris) were the most prevalent insect pests. Carabids, chrysopids, coccinellids, Nabis spp., Orius spp., spiders and opilionids were the most commonly occurring predaceous taxa. Circumstantial evidence from the field study and evidence from the laboratory study indicate that coccinellids play important roles in population growth of the above pests on alfalfa. Field and laborarory studies also provided evidence that carabids, coccinellids, chrysopids and nabids alone or together as a guild can suppress these pest populations on alfalfa. Parasitoids appeared to be important, as they killed a considerable percentage of Lygus spp. and A. pisum, but not of A. lineolatus. Aphidius ervi Haliday was the most prevalent aphid parasitoid. No control measures were required in hay fields, as swathing hay suppressed pest populations below damaging levels, partly through causing Lygus spp., and sometimes A. lineolatus, to move into adjacent seed fields. Conversely, insect pests were more numerous in seed fields, although these fields usually received chemical insecticides as pest control measures. Whether populations of natural enemies can be enhanced in seed alfalfa fields was examined, and it was found that nepetalactone, which is an aphid sex pheromone component, can be used to enhance natural enemy populations, and the benefits thereof, in seed fields. Successful rearing of Chrysoperla carnea (Stephens) and Chrysopa oculata Say larvae by using Megachile rotundata (Fabricius) (leafcutting bee) prepupae as the chrysopid larval diet expanded the use of leafcutting bees and provided a basis for inexpensive culture of chrysopids. The potential of insect pests and their natural enemies for management in connection with the current alfalfa production practices are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. Includes insect synonyms, common names, and geographic distribution Provides information on natural enemies Is thoroughly referenced for future research

Download or read book Industrial Oil Crops written by Thomas McKeon and published by Elsevier. This book was released on 2016-02-24 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial Oil Crops presents the latest information on important products derived from seed and other plant oils, their quality, the potential environmental benefit, and the latest trends in industrial uses. This book provides a comprehensive view of key oil crops that provide products used for fuel, surfactants, paints and coatings, lubricants, high-value polymers, safe plasticizers and numerous other products, all of which compete effectively with petroleum-derived products for quality and cost. Specific products derived from oil crops are a principle concern, and other fundamental aspects of developing oil crops for industrial uses are also covered. These include improvement through traditional breeding, and molecular, tissue culture and genetic engineering contributions to breeding, as well as practical aspects of what is needed to bring a new or altered crop to market. As such, this book provides a handbook for developing products from renewable resources that can replace those currently derived from petroleum. Led by an international team of expert editors, this book will be a valuable asset for those in product research and development as well as basic plant research related to oil crops. Up-to-date review of all the key oilseed crops used primarily for industrial purposes Highlights the potential for providing renewable resources to replace petroleum derived products Comprehensive chapters on biodiesel and polymer chemistry of seed oil Includes chapters on economics of new oilseed crops, emerging oilseed crops, genetic modification and plant tissue culture technology for oilseed improvement

Book excerpt: This book comprehensively compiles information on some of the major pests that afflict agricultural, horticultural and medicinal crops in particular as well as many polyphagous pests. Not only does this book deal with the pests of common globally produced crops it also addresses those of rarely dealt with crops such as seed spices, medicinal and aromatic plants. While the perspective of insect pests is largely Indian and South East Asian in context, the book does deal with globally problematic pests, particularly polyphagous ones. Not only will the readers be acquainted with the pests, their damaging potential and their life cycle but also with the latest methods of managements including ecofriendly measures being employed to keep pest populations at manageable levels. The 27 chapters in the book, are grouped into four sections primarily based on crop types, viz. pest of agricultural, horticultural and medicinal crops, and polyphagous pests, making the book easy to navigate. Each of the chapters is comprehensive and well illustrated and written by academicians who have dedicated their entire lives to the study of a particular crop-pest complex. The final chapter of this book provides an overview on the principles and processes of pest management.
