DOWNLOAD EBOOKThe literature is still one of our biggest frustrations to-day. There is, in one sense, too much of it, and in another not enough - for there are insufficient and inadequate published guidelines through this jungle. Last year two excellent books for students of ecological chemistry were published, one in France and one in England. The concordance of the references was a mere overall 3% rising to 7% in the chapters on pheromones. Even in the computer age, the channel remains a formidable barrier to the rapid exchange of biological information. At the present time we are in urgent need of compilations similar to John Feltwell's "The Large White Butterfly"; since the literature has become virtually unmanageable. This insect is now a demonstration object in the sixth form schoolroom; an experimental "rabbit" in the University laboratory; a test animal in virus and bacterial research projects; a tool for the study of flight mechanisms, migration, plant biochemistry, hormones, genetics, allergies, pigments, mimicry, etc. , etc. John Feltwell has, by this massive compilation, rendered us a great service - in fact he has given us a present of 4,000 hours of library time spent in 50 different libraries in seven countries. In the process he has collected 8000 references to the Large White. Of these, 4000 have been selected, and we are given a brief indication of their contents.

DOWNLOAD EBOOKParasitoid wasps are cosmopolitan, numerous and enormously diverse with probably one million or more species worldwide, most of which occur in the moist tropics. Their ecological importance is enormous although perhaps most evident in their major roles in the control of insect pest populations. In natural ecosystems they are integral in regulating populations of a vast number of insects, and therefore are key players in terrestrial food webs. Knowledge of their biology is still very poor because the current state of taxonomy is still in its infancy in most parts of the world.In this book, we provide an overview of the more than 30 families of parasitoid wasps that occur in the 11 countries in South East Asia. Particular emphasis is given to those most commonly encountered and reared, as well as to those used in biological control programmes. Outlines of the morphology, biology, ecology and behaviour of each family, as well as of various important subfamilies are presented. The current state of taxonomy in the region is summarised. Other chapters cover basic biology, behaviour, morphological terminology, phylogeny and methods of specimen collecting, preparation and rearing with particular relevance to the tropics. Modern molecular approaches to speeding taxonomic description of hyperdiverse taxa are considered in depth. All groups are illustrated with colour photographs. This book will be of value to professional entomologists, academics, entomology students and the growing body of amateur entomologists and insect photographers.
