Exempel på hur man kan använda AEDEAGUS i en mening

• If the male chooses to stay, he will thrill female’s pronotum, slide from female’s body and start copulation by inserting its aedeagus.
• An aedeagus (: aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.
• An ovipore is a pore-like sexual organ of a female insect that is inseminated by the spermatophores ejected by the aedeagus of a male insect during copulation.
• Males have an aedeagus through which they secrete sperm during copulation, while females have spermatheca for storing sperm and an ovipositor through which the oothecae are laid.
• Gonopods generally occur in one or more pairs, as opposed to the single (un-paired) reproductive organs such as the aedeagus of insects or the penis of harvestmen.
• Male celyphids lack an aedeagus and instead have paired gonapophyses that are used in copulation and are of key taxonomic value.
• Adults of Chrysomelinae are beetles with the following features: antennae inserted on or adjacent to anterior edge of head; inner face of each mandible with large membranous prostheca; each wing with only one anal cell (sometimes the wings are reduced or absent); metendosternite lateral arms without lobes; femora without internal spring sclerite; tibial spurs absent; tarsi without bifid setae; stridulatory mechanism absent; male aedeagus without tegminal ring and the testes not fused within a common membrane; female kotpresse absent.
• But unlike in Pyrophanes, the sheath of the aedeagus lacks paraprocts, and the seventh ventrite of the abdomen lacks the hairy lobes and points at its hind margin.
• In these bugs, the male intromittent organ is formed by the coupling of the aedeagus with the left paramere, as in bed bugs.
• repanda consists of a sclerotic tube, the aedeagus (Aed), and two narrow parameres (Par), all derived from abdominal segment nine.
• pensylvanica can be identified by a spotted mark on the frons below the antenna, a slender aedeagus, and a denser apical region of tergum 7.
• However, there are a few moths with similarly elongated whip-like aedeagi, and in these the female's ductus bursae is long and coiled to accommodate the aedeagus.
• These they resemble in general appearance as mentioned above, as well as having an anellus with lateral processes, a simple rodlike uncus, a strong gnathos, simple valvae and an aedeagus with separate cornuti.
• Tegumen very narrow dorsally, valvae tripartite into various shaped lobes of a complicate structure; no gnathos; aedeagus about as long as saccus, tubular and simple, no cornuti or coremata.
• In the case of the Neriid fly, Derocephalus angusticollis, males have been observed to have coevolved to have a flexible aedeagus.
• The male has a median tubular organ (called aedeagus or phallus) which is extended through an eversible sheath (or 'vesica') to inseminate the female.
• The inseminating organ, aedeagus, is small and slender with absence of cornutus (which also plays key role in transferring spermatophores).
• Diagnostic features are: uniformity, rather than asymmetry, of the rings of the ocelli; an undivided, dorsally domed uncus in the male genitalia; a short broad aedeagus with two apical fields of scobination, and a densely and robustly scobinate apex to the conical vesica; strong pouches lateral to the ostium in the female genitalia; a signum consisting of a single spine in the bursa copulatrix.
• Meharia is distinguished from all other Cossidae genus by a number of apomorphous characters: the specific “tineoid appearance”, the reduction of the lateral processes of the juxta, the specific dorsolateral sclerotization of the asymmetric aedeagus and the specific ribbon – like epiphysis.
• Male genitalia of Canadian specimens: Valva broad basally, then strongly tapering terminad; sacculus broad, rounded ventrally; median part of transtilla very slender, with small apical thorns; aedeagus distinctly bent; cornutus slender, straight.
