Morphology and protein pattern of the accessory reproductive glands of male Blattella germanica (Dictyoptera: Blattellidae)
- N/A
The basic function of the accessory reproductive glands (ARG) of male insects is to provide materials for the production of the spermatophore. The morphology of the ARG of Blattella germanica, including the ejaculatory pouch and duct, the uricose glands, the utricles of the mushroom-shaped body, and the conglobate gland are described. Special attention is given to the fine discrimination of the different tubules associated with the ARG, particularly in the mushroom-shaped body, where up to 12 types of tubule have been recognized. The analysis considered not only morphology and biometry, but also protein pattern. The remarkable diversity found reveals a fascinating complexity, which can be explained if the roles played by the spermatophore they produce are considered.
