Male Reproductive System Of Insects. Insect Reproduction function of male reproductive system make spermatozoa storage send them off with proteins with many functions deliver the whole package to the females testes seminal vesicles accessory glands external genitalia general plan of male reproductive system testis follicles 1-100 testes can be separate of. Armandi were collected from the bark of infested P. It is elongated and presented above the intestine of the insect. Many other aspects of reproduction including copulation and regulation of physiological processes are discussed in detail in Chapter 5.
STRUCTURE OF THE MALE. Each testes is subdivide into functional units - Follicles - sperm is produced. The chapter describes the main and accessory organs of male and female reproductive systems in insects including development of these organs and of eggs and sperm. At the distal end of each follicle-group of germ cells - Spermatogonia. The ninth chapter covers endocrine influence on reproduction in the male insect. Anatomy of the internal reproductive organs The male reproductive organs typically consist of a pair of testes connecting with paired seminal vesicles and a median ejaculatory duct Fig.

Generalized male and female systems are depicted in Fig. Reproductive System The reproductive organs of insects are similar in structure and function to those of vertebrates. In most insects there are also a number of accessory glands which open into the vasa deferentia or the ejaculatory duct. Reproductive system of insects 1. Each testes is subdivide into functional units - Follicles - sperm is produced. Both types of gametes are haploid and unicellular but eggs are usually much larger in volume than sperm.
