    Aedeagus of Pentodon idiota Photomicrograph of the aedeagus of water scavenger beetle Tormissus linsi (from above). An aedeagus (/ i ˈ d i. ə. ɡ ə s / or / i. d i ˈ eɪ. ɡ ə s / [1] [2] pl. aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.

  3. Insect reproductive system - Wikipedia

    en.wikipedia.org/wiki/Insect_reproductive_system

    Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.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 ...

  4. Lepidoptera genitalia - Wikipedia

    en.wikipedia.org/wiki/Lepidoptera_genitalia

    Male genitalia of Lepidoptera Female genitalia of Lepidoptera. The study of the genitalia of Lepidoptera is important for Lepidoptera taxonomy in addition to development, anatomy and natural history. The genitalia are complex and provide the basis for species discrimination in most families and also in family identification. [1]

  5. Mosquito - Wikipedia

    en.wikipedia.org/wiki/Mosquito

    A human's unique body odour indicates that the target is actually a human host rather than some other living warm-blooded animal (as the presence of CO 2 shows). Body odour, composed of volatile organic compounds emitted from the skin of humans, is the most important cue used by mosquitoes. [42]

  6. Male reproductive system - Wikipedia

    en.wikipedia.org/wiki/Male_reproductive_system

    The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body, and within the pelvis. The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse ...

  7. Insect physiology - Wikipedia

    en.wikipedia.org/wiki/Insect_physiology

    The female insect's main reproductive function is to produce eggs, including the egg's protective coating, and to store the male spermatozoa until egg fertilisation is ready. The female reproductive organs include paired ovaries which empty their eggs (oocytes) via the calyces into lateral oviducts, joining to form the common oviduct.

  8. Male accessory gland - Wikipedia

    en.wikipedia.org/wiki/Male_accessory_gland

    The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...

  9. Insect morphology - Wikipedia

    en.wikipedia.org/wiki/Insect_morphology

    Insect blood or haemolymph's main function is that of transport and it bathes the insect's body organs. Making up usually less than 25% of an insect's body weight, it transports hormones, nutrients and wastes and has a role in, osmoregulation, temperature control, immunity, storage (water, carbohydrates and fats) and skeletal function. It also ...
