Abstract
The exogenous dose of 20-hydroxcy Ecdysone (20-HE) used in the present
study induced an increase in the size and the secretory activity of the different types
of alveoli of salivary glands in nymphet Hyalomma dromedan'r' during its
developmental stages, Also, it causes salivary gland degeneration. The results
suggest that the (20-HE) enhance synthesis and release of tick salivary gland
degeneration factor (the degeneration factor), which is probably an ecdysteroid. (20-
HE) seems to provide a stimulus for synthesis of protein. lipids and glycogen drates.
