argasid การใช้

• The oldest example is an argasid bird tick from Cretaceous New Jersey amber.
• Argasid ticks have up to seven nymphal stages ( instars ), each one requiring a blood meal.
• The digestive system in both Ixodid and argasid ticks is histologically divided into foregut, midgut and hindgut.
• The adult female argasid tick can lay a few hundred to over a thousand eggs over the course of her lifetime.
• During feeding, any excess fluid is excreted by the coxal glands, a process which is unique to argasid ticks.
• Another argasid tick, " Argas africolumbae ", was found in a nest of the closely related rock martins in Kenya.
• Argasid ticks, unlike ixodid ticks, may go through up to seven nymphal stages ( instars ), requiring a meal of blood each time.
• The Nuttalliellidae can be distinguished from both ixodid and argasid ticks by a combination of a projecting capitulum at the front and a soft, leathery skin.
• Apart from " Chelopistes lervicola " described as an ectoparasite of this species, an Argasid tick " Argas himalayensis " has been noted.
• The argasid tick " Argas theilerae " ( Hoogstraal and Kaiser, 1970 ), " Theiler's African white-backed vulture argasid, " was named to honor Dr Theiler for her many contributions to tick research.
• The argasid tick " Argas theilerae " ( Hoogstraal and Kaiser, 1970 ), " Theiler's African white-backed vulture argasid, " was named to honor Dr Theiler for her many contributions to tick research.
• Some strains of entomopathogenic fungi have been found to be effective against this tick and others in the genus " Ornithodoros " in a study which concluded the fungi could be used as biocontrol agents for argasid ticks; the name of this is called hyperparasitism.
• The process by which Ixodid and Argasid ticks feed is termed "'telmophagy "'( = pool feeding ) . ( This contrasts with the process of solenophagy, used by mosquitos, in which feeding is direct from a small venule . ) The resultant pool expands as a result of the anticoagulants released from the salivary glands.
