[3], The males of many species of Papilionoidea are furnished with secondary sexual characteristics. fertilisation ? Apterygotes possess a pair of styles; rudimentary appendages that are serially homologous with the distal part of the thoracic legs. Flowers have both male and female parts that work together to reproduce. However, most male insects have a pair of testes, inside of which are sperm tubes or follicles that are enclosed within a membranous sac. The uniqueness of genitalia of a species led to the use of the morphological study of genitalia as one of the most important keys in taxonomic identification of taxa below family level. Showing top 8 worksheets in the category - Male And Female Reproductive System Of Butterfly. At the time of fertilization, the eggs travel along oviducts to be fertilized by the sperm and are then expelled from the body ("laid"), in most cases via an ovipositor. [2][3], The arrangement of genitalia is important in the courtship and mating as they prevent cross-specific mating and hybridisation. The male reproductive system of cockroach consists of a pair of testes, vasa deferentia, an ejaculatory duct, utricular gland, phallic gland and the external genitalia. Reproductive System The reproductive organs of insects are similar in structure and function to those of vertebrates: a male’s testes produce sperm and a female’s ovaries produce eggs … Insect genitalia, especially male genitalia, is often directionally asymmetrical, and this trait has evolved multiple times in various orders. Start studying Male and Female Reproductive system terms. The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. Configurations There are three basic configurations of genitalia in the majority of the Lepidoptera based on how the arrangement in However, apterygotes (bristletails and silverfish) and many immature aquatic insects have abdominal appendages. Their reproductive systems are made up of a pair of ovaries, accessory glands, one or more spermathecae, and ducts connecting these parts. Male And Female The oviducts of the female join together to form a common duct (called the 'oviductus communis') which leads to the vagina. They can produce glue and protective substances for coating eggs or tough coverings for a batch of eggs called oothecae. When a male finds a willing female, he pushes a huge package of sperm and other proteins into her reproductive tract. These terminal abdominal segments have excretory and sensory functions in all insects, but in adults there is an additional reproductive function.[2]:49. The diagram shows a sperm. The ovipore may be at the end of a modified 'ovipositor' or surrounded by a pair of broad setose anal papillae. The ovaries make eggs and accessory glands produce the substances to help package and lay the eggs. ? Unlike the female reproductive system, most of the male reproductive system is located outside of the body. Generally, the first seven abdominal segments of adults (the pregenital segments) are similar in structure and lack appendages. Variation of this ground plan includes the fusion of terga or terga and sterna to form continuous dorsal or ventral shields or a conical tube.

The sperm, when released from the capsule, swims directly into or via a small tube (the 'ductus bursae') into a special seminal receptacle (the 'spermatheca'), where the sperm is stored until it is released into the vagina for fertilisation during egg laying, which may occur hours, days, or months after mating. The follicles connect to the vas deferens by the vas defferens, and the two tubular vasa deferentia connect to a median ejaculatory duct that leads to the outside. She’ll shunt … In meroistic ovaries, the eggs-to-be divide repeatedly and most of the daughter cells become helper cells for a single oocyte in the cluster. The number of eggs that the insect is able to make varies according to the number of ovarioles, with the rate at which eggs develop being also influenced by ovariole design. These vesicles are derived from the coxal and trochanteral endites (inner annulated lobes) of the ancestral abdominal appendages. With the advent of DNA analysis, the study of genitalia has now become just one of the techniques used in taxonomy. Close up of the hardened Parnassius sphragis extruding 2 to 3 mm behind the abdomen. The orthopteran family Acrididae has 11 segments, and a fossil specimen of Zoraptera has a 10-segmented abdomen.[1]. The male external genitalia have been used widely to aid in distinguishing species, whereas the female external genitalia may be simpler and less varied. SmartDraw includes 1000s of … Terga are separated from each other and from the adjacent sterna or pleura by a membrane. The joining together of male and female gametes to form a zygote is called ? The diagram below represents the female reproductive system. Spermathecae store sperm for varying periods of time and, along with portions of the oviducts, can control sperm use. These external structures include the penis, scrotum, and … Paternity testing of insects has revealed that some, and probably many, female insects use the spermatheca and various ducts to control or bias sperm used in favor of some males over others.

The organs concerned specifically with mating and the deposition of eggs are known collectively as the external genitalia, although they may be largely internal. [1]:885, The ground plan of the abdomen of an adult insect typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are (1) liberation of an ovum, or egg, at a specific time in the reproductive … You can read Diagram Of A Male And Female Reproductive System PDF direct on your mobile phones or PC. male and female reproductive systems This chapter begins with a description of the male and female reproductive systems followed by a section on sex determination. A pair of appendages, the cerci, articulates laterally on segment 11; typically these are annulated and filamentous but have been modified (e.g. Some people need to learn this in more depth than others, but we are fascinating individuals. Gonads in the male and females are testis and ovaries respectively while gametes in males are sperms and In females are eggs or ova. Penis ? Variation in abdominal segment number is considerable. The ejaculatory duct is derived from an invagination of the epidermal cells during development and, as a result, has a cuticular lining. Sperm, produced by the male in one testis or more commonly two, is transmitted to the female during mating by means of external genitalia. The remainder of the male reproductive system is derived from embryonic mesoderm, except for the germ cells, or spermatogonia, which descend from the primordial pole cells very early during embryogenesis. Each segment of the abdomen is represented by a sclerotized tergum, sternum, and perhaps a pleurite. Which part of the male reproductive system transfers sperm into the woman? The tail enables the sperm to swim. During the embryonic stage of many insects and the postembryonic stage of primitive insects, 11 abdominal segments are present.

The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them remain separate. The reproductive organs of insects are similar in structure and function to those of vertebrates: a male’s testes produce sperm and a female’s ovaries produce eggs (ova). [1]:880, Accessory glands or glandular parts of the oviducts produce a variety of substances for sperm maintenance, transport, and fertilization, as well as for protection of eggs.
