May 1976 R.G.D. Part I ANATOMY AND PHYSIOLOGY Chapter I INTRODUCTION Definition of the Insecta (Hexapoda) The insects are tracheate arthropods in which the body is divided into head, thorax and abdomen. A single pair of antennae (homologous with the anten nules of the Crustacea) is present and the head also bears a pair of mandibles and two pairs of maxillae, the second pair fused medially to form the labium. The thorax carries three pairs of legs and usually one or two pairs of wings. The abdomen is devoid of ambulatory appendages, and the genital opening is situated near the posterior end of the body. Postembryonic development is rarely direct and a metamorphosis usually occurs.

G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OF INSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.

Available in PDF, EPUB and Kindle. Book excerpt: Morphology and Evolution of the Insect Abdomen: With Special Reference to Developmental Patterns and Their Bearings Upon Systematics focuses on the morphology and evolution of the skeletal structures of the insect abdomen and the internal reproductive system. Emphasis is placed on patterns of development and their implications for systematics. Comprised of 44 chapters, this book begins with an introduction to the principles of structural evolution, paying particular attention to morphogenetical regularities and anagenesis, heterochrony, substitution and homology, and analogy. The next section is devoted to various aspects of the insect abdomen including abdominal segmentation, appendages, and ovipositor as well as the male external genitalia, the male and female efferent duct, and the abdominal ganglia. The final section deals with the abdomen of a wide range of insect classes such as Protura, Collembola, Orthoptera, Coleoptera, Homoptera, Mantodea, and Diptera. This monograph will be of interest to entomologists, physiologists, and evolutionary biologists.

Download or read book The Physiology of Insect Reproduction written by Franz Engelmann and published by Elsevier. This book was released on 2013-10-22 with total page 325 pages. 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 of egg maturation. The ninth chapter covers endocrine influence on reproduction in the male insect. The next chapters discuss oviposition, heterogony, and viviparity. The last two chapters deal with functional hermaphroditism and insect societies, respectively. The book will be of great use to students and researchers in the field of entomology.
