Reproduction in Cockroach
- Cockroaches are dioecious. The male and female reproductive organs are present in different organisms.
- Both sexes have well-developed reproductive organs.
Male Reproductive System
- It consists of a pair of testes one lying on each lateral side in the 4th-6th abdominal segments.
- From each testis arises a thin vas deferens, which opens into the ejaculatory duct through the seminal vesicle.
- The ejaculatory duct opens into the male gonopore situated ventral to the anus.
- A characteristic mushroom-shaped gland is present in the 6th-7th abdominal segments which function as an accessory reproductive gland.
- The external genitalia are represented by male gonapophysis or phallomere (chitinous asymmetrical structures, surrounding the male gonopore).
- The sperms are stored in the seminal vesicles and are glued together in the form of bundles called spermatophores which are discharged during copulation.
