Spermatheca of Acanthoscurria geniculata (Brazilian Giant White Knee Tarantula)

The spermatheca (pronounced /spərməˈθiːkə/ plural: spermathecae /spərməˈθiːsiː/), also called receptaculum seminis (plural: receptacula seminis), is an organ of the female reproductive tract in insects, bees, some molluscs, oligochaeta worms and certain other invertebrates and vertebrates.^[1] Its purpose is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body, and can sometimes be the site of fertilization when the oocytes are sufficiently developed.^[2]

Some species of animal have multiple spermathecae. For example, certain species of earthworms have four pair of spermathecae—one pair each in the 6th, 7th, 8th, and 9th segments. The spermathecae receive and store the spermatozoa of another earthworm during copulation.^[3] They are lined with epithelium and are variable in shape: some are thin, heavily coiled tubes, while others are vague outpocketings from the main reproductive tract. It is one of the many variations in sexual reproduction.

An apiculturist may examine the spermatheca of a dead queen bee to find out whether it had received sperm from a male.^[4] In many species of stingless bees, especially Melipona bicolor, the queen lays her eggs during the provisioning and oviposition process and the spermatheca fertilizes the egg as it passes along the oviduct. The haplo-diploid system of sex determination makes it possible for the queen to choose the sex of the egg.^[5]

交尾中断や多回交尾がミヤコカブリダニの精子授受や産卵に与える影響

交尾を途中で強制的に終了させた雌成虫および多回交尾したミヤコカブリダニ雌成虫を使って，精子の授受と産卵行動を4温度条件下（18, 25, 30, 35℃）で観察した．交尾行動の一環である精子の授受は，交尾直後に雌成虫のスライド標本を作成し受精嚢を検鏡することと，生存させた雌成虫の産卵行動を記録することで推定した．高い温度区では精子の授受速度が速く，交尾終了雌の産卵も短時間から始まった．雌成虫が1対 …
