Methods for the Study of Pest Diabrotica
Insects as a group occupy a middle ground in the biosphere between bac at one extreme, amphibians and mammals at the other. teria and viruses of insects present special problems to the The size and general nature study of entomology. For example, many commercially available instru ments are geared to measure in grams, while the forces commonly en countered in studying insects are in the milligram range. Therefore, tech niques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given ...
Western Corn Rootworm
"This book provides a comprehensive review of current knowledge of this insect pest and how it might be managed both in North America and in Europe. Comparisons are drawn between plant protection techniques currently applied in North America and their potential application in Europe. Cultural, biotechnical and biological control measures are also addressed, as are ecological baseline data such as population dynamics of the pest in North America and Europe, economic thresholds and aspects of its behaviour. This book will be of significant interest to those working in the areas of entomology and integrated crop protection throughout the world."--BOOK JACKET.
New Developments in the Biology of Chrysomelidae
This book summarizes what is actually known about the biology of Leaf Beetles. It is the most recent study in the field. As we are well aware, Chrysomelidae, one of the three largest families of beetles, are of great economic importance since they can be a serious pest to crops or, on the other hand, can be used to destroy imported weeds. This is due to the selectivity of their feeding preferences. In this way, Chrysomelidae are an invaluable tool for studying plant selection mechanisms. The many and varied topics dealt with in this book cover almost all aspects of phylogeny, classification, paleontology, parasitology, biogeography, defenses, population biology, genetics and biological contr...
On the Plurality of Civilizations
348 pages. In the XXth c. there were several authors struggling with the notion of civilization - Oswald Spengler (Der Untergang des Abendlandes), Arnold Toynbee (A Study of History), Anton Hilckman (Orient et Occident. Une Philosophie de l'histoire), Samuel Huntington (A Clash of Civilizations). Among them Feliks Koneczny was the most original. He expanded his general views on how to classify civilizations in the volume On the Plurality of Civilizations. He did not believe that civilizations are like organisms which have a birth, a youth, and adult life, a decline and death. He pointed out that some civilizations exist for millennia and show no decline while others are short lived. Koneczny...
The Cerambycidae of North America, Part VII, No. 1
This volume concludes the taxonomy and classification of the family Cerambycidae of America north of Mexico. This part includes the remainder of the subfamily Lamiinae, tribes Acanthocinini, Cyrtinini, Saperdini, Phytoeciini, Tetraspini, and Hemilophini. The 32 genera and 138 species are all fully described with keys included to separate all taxa. Complete synonymical bibliographies are presented along with 54 illustrations.
Insect Pests of Potato
This fully revised and updated second edition of Insect Pests of Potato now includes an opening section with a basic overview of agronomic and economic issues as they relate to potato production. It also features a new section that reviews potato production, as well as problems caused by insect pests and solutions to these problems, in all major potato-growing regions of the world. Further, a new section discusses theoretical foundations of potato pest management and includes chapters on ecological theory, evolutionary theory, and a case study on their applications to elucidate differences between Eastern and Western populations of Colorado potato beetle in North America. There is also a new...

Lemberg, Lwow, and Lviv 1914-1947
Known as Lemberg in German and Lwów in Polish, the city of L'viv in modern Ukraine was in the crosshairs of imperial and national aspirations for much of the twentieth century. This book tells the compelling story of how its inhabitants (Roman Catholic Poles, Greek Catholic Ukrainians, and Jews) reacted to the sweeping political changes during and after World Wars I and II. The Eastern Front shifted back and forth, and the city changed hands seven times. At the end of each war, L'viv found itself in the hands of a different state. While serious tensions had existed among Poles, Ukrainians/Ruthenians, and Jews in the city, before 1914 eruptions of violence were still infrequent. The changes ...
