Book excerpt: Excerpt from Results of Experiments With Miscellaneous Substances Against Bedbugs, Cockroaches, Clothes Moths and Carpet Beetles Upon careful study Of the habits of roaches it has been found that these insects frequently cleanse their legs and antennae. When any dirt or powder comes' in contact with the appendages, these are at Once drawn through the mouth parts of the insects and in this way cleaned. As a result, a certain amount of any powdered substance applied directly to a roach, or through which it may crawl, is thus taken into the mouth. In this way any poison, whether distasteful or not, finds its way into the stomach. Therefore it is not necessary to mix a stomach poison, in powdered form, with an attractive bait, ' since the chances are much greater that the poison will reach the stomach Of the roach through its habit Of cleansing itself than through the eating of the poisoned bait. True contact poisons, as, for example, mineral-oil sprays, kill by coming in contact with the body. This may result (1) through direct application or (2) by coming in contact with the roach after it has been applied.

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.]

Available in PDF, EPUB and Kindle. Book excerpt: Medical and Veterinary Entomology, Second Edition, has been fully updated and revised to provide the latest information on developments in entomology relating to public health and veterinary importance. Each chapter is structured with the student in mind, organized by the major headings of Taxonomy, Morphology, Life History, Behavior and Ecology, Public Health and Veterinary Importance, and Prevention and Control. This second edition includes separate chapters devoted to each of the taxonomic groups of insects and arachnids of medical or veterinary concern, including spiders, scorpions, mites, and ticks. Internationally recognized editors Mullen and Durden include extensive coverage of both medical and veterinary entomological importance. This book is designed for teaching and research faculty in medical and veterinary schools that provide a course in vector borne diseases and medical entomology; parasitologists, entomologists, and government scientists responsible for oversight and monitoring of insect vector borne diseases; and medical and veterinary school libraries and libraries at institutions with strong programs in entomology.

Download or read book The Economic Importance of Insects written by Dennis S. Hill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

Download or read book Champagne and Meatballs written by Bert Whyte and published by Athabasca University Press. This book was released on 2011 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Active for over 40 years with the Communist Party of Canada, Bert Whyte was a journalist, an underground party organizer and soldier during World War II, and a press correspondent in Beijing and Moscow. But any notion of him as a Communist Party hack would be mistaken. Whyte never let leftist ideology get in the way of a great yarn. In Champagne and Meatballs--a memoir written not long before his death in Moscow in 1984--we meet a cigar-smoking rogue who was at least as happy at a pool hall as at a political meeting. His stories of bumming across Canada in the 1930s, of combat and comaraderie at the front lines in World War II, and of surviving as a dissident in troubled times make for compelling reading. The manuscript of Champagne and Meatballs was brought to light and edited by historian Larry Hannant, who has written a fascinating and thought-provoking introduction to the text. Brash, irreverent, informative, and entertaining, Whyte's tale is history and biography accompanied by a wink of his eye--the left one, of course.

Download or read book Vetiver Grass written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

Download or read book Mites Ecology Evolution Behaviour written by David Evans Walter and published by Springer Science & Business Media. This book was released on 2013-10-08 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.
