Book excerpt: Excerpt from Contributions to the Biology of the Danish Culicidae In the time from 1910 - 1920 a series of shorter papers, dealing with the biology of the European species, appeared, and the biological facts, mentioned by the American authors, were generally corroborated by the European ones. In my opinion this literature very often by no means comes up to the standard which should be exacted for scientific work. After brief reflection I resolved that I would carry to an end my own studies in spite of the whole American and European literature, and moreover that during the study I would not take the slightest notice of it. My leading scientific views were the following. From a purely scientific point of view, I have always regarded the question, who first made a biological observation as a matter of sublime indifference. It must never be forgotten, that even with regard to biological observations which can only rarely be committed to paper with the same convincing exactness as an anatomical structure, the exact apprehension of a given fact can only be acquired through repeated observation. It is further of the greatest significance that the biological observations are tested by different scientists and in different latitudes; only in that way can our suppositions and hypotheses be registered among real scientific facts. It must further be remembered that the study of Nature must always begin with the slightest possible literary ballast. He who has first crammed his head with all that has been written upon a subject, will at the moment of observa tion, when standing face to face with Nature, soon understand that his whole learning is only felt as a burden and restricts his power of observation. I for my own part have always been of the opinion that it is exactly the smallest equipment of human knowledge which gives the greatest peace in my studies, creates the scientific sovereignty over observations and thoughts and as far as possible moves the milestones of time nearer to the borders of eternity.

This book was released on 2002-05-14 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global environment is changing rapidly under the impact of human activities. An important element in this change is related to global climate modification. Experts from the natural and social sciences with a strong interest in history discussed common topics of great interest to society. Can the study of climate and history help in devising strategies for coping with this change? What might be the type of information most useful in this context? What are the pitfalls awaiting the unwary? These and similar questions were discussed during a four-day workshop. The resulting proceedings contain comprehensive papers of broad interest, thematic back-ground papers and reports of study groups. Apart from scientists, the papers should interest graduate students and lecturers.

Download or read book Biology of Blood Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
Download or read book Biological Control Measures of Success written by G. Gurr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
Download or read book Marine Insects written by Lanna Cheng and published by North-Holland. This book was released on 1976 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. 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.]
