Abstract EN
Ticks are protected against ants by release of an allomonal defense secretion from the large wax glands (or type 2 glands) that line their bodies.
To explore how the large wax glands operate, before and after microscopic observations of these glands (nonsecreted versus secreted test groups), mass determinations were made for Rhipicephalus sanguineus that had been exhausted of secretion by repeated leg pinching to simulate attack by a predator.
Prior to secretion, the glandular organ is fully intact histologically and matches the sensillum sagittiforme, a key taxonomic structure described in the 1940s.
The large wax gland is innervated and responds to pressure stimulation as a proprioceptor that stimulates the secretory response.
Histological observations after secretion has occurred show that the entire glandular contents and associated cells are jettisoned out of the gland like a syringe.
The glandular cellular components are subsequently rebuilt by underlying hypodermal cells within a few days so that secretion can take place again.
Presumably, the active allomonal ingredients (hydrocarbons) are released when these derived epidermal cells reach and burst onto the cuticular surface.
Our conclusion is that the large wax glands are holocrine and feature intermittent regeneration.
