Book excerpt: Excerpt from Evaluating Diatomaceous Earth, Silica-Aerogel Dusts, and Malathion to Protect Stored Wheat From Insects Diatomaceous earth may be applied to stored grain for insect control according to label instructions approved by epa. Agricultural Marketing Service (ams) provides instructions to licensed grain inspectors for grading grain containing diatomaceous earth (under GR Instruction 918 4 Aux. 1, May 9, An applicant who has grain that contains or appears to contain diatomaceous earth and who wishes to have the grain graded may file a written ap plication with the grain inspector. If diatomaceous earth is then found, the grain will not be downgraded on the basis of the presence of an unknown or foreign substance. Malathion has an established tolerance of 8 parts per million when applied to stored wheat for insect control and may be used according to label instructions. Caution: Pesticides can be injurious to humans, domestic animals, beneficial insects, desirable plants, and fish or other Wildlife - ii they are not handled or applied properly. Use all pesticides selectively and carefully. Follow recommended prae tices for the disposal of surplus pesticides and pesticide containers.

This book was released on 2018-05-02 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Evaluation of Four Inert Dusts for the Protection of Shelled Corn in Georgia From Insect Attack Commercial grades on corn samples were lowered by treatment with the inert dusts. Test weight was lowered an average of pounds per bushel on corn treated with diatomaceous earth and pounds per bushel on corn treated with silica aerogel. The test weight of the untreated and malathion-treated corn was almost unchanged. Dust treatments reduced the loading capacity of the grain conveyor to one-half its capacity for untreated or malathion-treated shelled corn. Dust-treated corn was packed and very difficult to probe for samples. The overall moisture content of the corn decreased slightly during the year's storage. Residues on malathion-treated corn averaged p.p.m. Immediately after treatment and decreased to p.p.m. By the end of the year. All treatments reduced the initial insect infestation to a very low level in the corn. The number of insects in the untreated check corn, however, continued to increase, and by the second month of storage, this corn was weevily according to official Grain Standards of the United States. Sg-68 and malathion were the most effective in keeping insect populations from develop ing in the corn. Perma-guard, Kenite, and cab-o-sil lost much of their effectiveness after 9 months' of storage, as evidenced by increases in numbers of live insects, development of insect progeny, and insect-damaged kernels. One bin of corn treated with cab-o-sil was weevily after 1 year's storage. Perma-guard provided the shortest residual protection. One bin became weevily at 11 months and two more bins at 12 months.

Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

Pesticide resistance is becoming more frequent and widespread with more than 500 insect species known to have become resistant to synthetic insecticides. On the other hand, consumers increasingly demand agricultural products without any pesticide residues. This book, for the first time, shows the alternative: solely physical methods for plant protection by means of thermal, electromagnetic, mechanical and vacuum processes. A glossary rounds up this extremely valuable book.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to assess, evaluate and critically analyze the methods that are currently available for a judicious pest management in durable food. It presents and analyzes a vast amount of methods that are already in use in “real world” industrial applications. After the phase-out of methyl bromide, but also the withdrawal of several insecticides and the continuously updated food safety regulations, there is a significant knowledge gap on the use of risk-reduced, ecologically-compatible control methods that can be used with success against stored-product insect species and related arthropods. The importance of integrated pest management (IPM) is growing, but the concept as practiced for stored products might differ from IPM as historically developed for field crops. This book discusses a wide variety of control strategies used for stored product management and describes some of the IPM components. The editors included chemical and non-chemical methods, as both are essential in IPM. They set the scene for more information regarding emerging issues in stored product protection, such as emerging, alien and invasive species as threats for global food security, as well as the importance of stored-product arthropods for human health. Finally, the analysis of the economics of stored product protection is presented, from theory to practice.

Available in PDF, EPUB and Kindle. Book excerpt: This reference discusses the fundamentals of stored-product entomology that need to be considered in planning, implementation, and evaluation of a pest management program. It is based on the review of an extensive database of references and many years of research on stored-product insect problems by the expert authors. The information in this book helps answer consumers’ concern about pesticide residues in food by providing helpful IPM and alternative approaches for pest management. It provides the basic information needed to manage pests with and without the use of chemicals. Managing pests requires a thorough understanding of insect biology, behavior, ecology, sampling, pros and cons of management options, and responses of insects to the various management options. This comprehensive book covers all of these topics, beginning with a discussion of the scope of stored-product entomology. It also provides insight into the diversity of foods and habitats utilized by stored-product insects, the types of economic losses attributable to them, and the ways in which an understanding of their biology can be used to study or manage these insects. Insect mobility, sources of insect infestation, sampling, life history, and population growth are discussed as well, as they play an important role in developing an effective sampling program. In addition, decision aids, the cost of management methods, and the resistance of insects to management methods are covered. For insight into the thought process of choosing treatment options, eight pest management methods are thoroughly described, including a statement of the basic operating principle and background information. For help choosing various chemical and nonchemical methods for diverse situations, the advantages, disadvantages and implementation options for each method are given. Students, extension educators, consultants, food industry sanitarians and managers, legislators, regulators, and insect pest management professionals are sure to find information that will help them to improve pest management. Study questions at the end of each chapter Suggested supplemental reading, including books, conference proceeding papers, literature reviews, research papers, government publications, and popular articles General overview of the biology for a basic understanding of pest control issues Guides the reader through the thought process of designing a pest control program or research study Images of the most damaging of stored-product insect pest species for identification of families Quick methods for distinguishing closely related stored-product insect species
