The Physiology of Insect Reproduction

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.
