Book excerpt: In retrospect, the range of topics covered in this monograph, although forming a coherent ensemble, is so extensive that a detailed discussion could easily extend to three or four times the current length. My approach has been to identify the critical issues, summarize the major accomplishments, and to suggest promising avenues for future research. To facilitate this sum mary presentation, I have limited the literature review largely to material published after 1970, extending to material appearing late in 1990. I gratefully acknowledge the advice of many colleagues, particularly the valuable criticisms of Drs. Warren Burggren, Joseph Kunkel, Randall Phillis, and John Stoffolano. I also wish to thank Mrs. Elizabeth Brooks for secretarial assistance. Finally, thanks are due to Dr. D. Czeschlik and his staff at Springer Verlag for their patience and support.

Available in PDF, EPUB and Kindle. Book excerpt: Cell biology is moving at breakneck speed, and many of the results from studies on insects have helped in understanding some of the central problems of biology. The time is therefore ripe to provide the scientific community with a series of up-to-date, well illustrated reviews of selected aspects of the sub microscopic cytology of insects. The topics we have included fall into four general groups: seven chapters deal with gametogenesis, four concern develop ing somatic cells, seventeen chapters describe specialized tissues and organs, and three chapters cover cells in pathological states. These accounts are illustrated with over 600 electron micrographs. The more than 1100 pages in the two volumes of Insect Ultrastructure combined labors of 49 dedicated contributors from II countries. represent the These authors have digested and critically summarized a very large body of information, and some measure of this effort can be gained from consulting the bibliographies that close each of the 31 chapters. These contain 2400 publica tions authored by 1500 different scientists. However, before we congratulate ourselves on the advanced state of our knowledge, it is worth remembering that representatives of less than 0.01 % of the known species of insects have been examined with the electron microscope.

Book excerpt: This book consisting of ten review chapters contributed by leading workers in their respective fields, from around the world, covers the whole subject of insect reproduction.It begins with the basic physiological questions of insect reproduction, moves on to discuss the new advances seen in the fields of behavioural and ecological mechanisms, and culminates by examining the recent work on evolutionary biology and its application in the field. Each chapter, although including a brief review of the basic seminal work, focuses mainly on the advances made within the last ten years and highlights those areas in which the respective authors see the greatest scope for further important advances

Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Insect Reproduction provides a comprehensive coverage of insect reproductive system. The title details basic phenomena governing reproductive processes in insects, with the whole spectrum of an insect reproductive cycle. The text first covers insect genitalia, and proceeds to discussing sex determination. Next, the selection talks about the development of unfertilized eggs in insects. The text also deals with gonadal development, along with insect mating behavior. Chapter 7 details the factors that affect egg production and fecundity, while Chapter 8 tackles hormonal control ...

Available in PDF, EPUB and Kindle. Book excerpt: The male reproductive system, which is made up of the testes, scrotum, epididymis, vas deferens, seminal vesicles, prostate gland, bulbourethral gland, ejaculatory duct, urethra, and penis, functions mainly in the production, nourishment, and temporary storage of spermatozoa. Epigenetic modifications are essential to regulate normal gonadal development and spermatogenesis. The sperm epigenome is highly susceptible influence by a wide spectrum of environmental stimuli. This book focuses on the male reproductive system, discussing topics ranging from aspects of anatomy and risk factors for male infertility to clinical techniques and management of male reproductive health.

Available in PDF, EPUB and Kindle. Book excerpt: There are more than 6000 species belonging to twenty-seven orders in the Class Mammalia. Comparative studies of this diverse and magnificent array of extant species provide valuable opportunities to formulate and test hypotheses concerning the evolution of reproduction. This is the first book to explore, in depth and breadth, the complex interrelationships that exist between patterns of mating behaviour and the evolution of mammalian reproductive anatomy and physiology. It focuses upon the role that copulatory and post-copulatory sexual selection have played during the evolution of the monotremes, marsupials and placental mammals, and examines the effects of sperm competition and cryptic female choice upon coevolution of the genitalia in the two sexes. In addition, due weight is also given to discussions of the modes of life of mammals, and to the roles played by natural selection and phylogeny in determining their reproductive traits.

Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.

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.
