genital duct

The study of nephridia and genital ducts since 1895.

On the coelom, genital ducts, and nephridia.

The pair of testes of the insect are connected to the aedeagus through the genital ducts.

The accessory genital ducts, the seminal vesicle, prostate glands, and the bulbourethral glands, produce most of the seminal fluid.

Gonads appear; the male genital duct of one terminates near the female genital duct of the other, permitting cross-fertilization.

Pallial roof has black pigment bands along edges of ctenidium and dorsal edge of genital duct; visceral coil pale except for black pigment on testis.

The female genitals have a long, straight and tubular genital duct with a plain anal end in the type species T. mavors, but variation within the genus is insufficiently studied.

The uterus is a long tube like structure that also leads away from the ovary and joins up with the ejaculatory duct to form the genital duct which leads to a genital sinus.

While the layout of internal genital ducts and openings of the female genitalia depends upon the taxonomic group that insect belongs to, the internal female reproductive system of all Lepidopterans consists of paired ovaries and accessory glands which produce the yolks and shells of the eggs.
