Argasid ticks have up to seven nymphal stages , each one requiring blood ingestion, and as such, Argasid ticks undergo a multihost life cycle. Because of their hematophagous (blood-ingesting) diets, ticks act as vectors of many serious diseases that affect humans and other animals.
Life-cycle of a typical three-host tick Development stages of ixodid tick Rhipicephalus appendiculatus; E=eggs, L=larvae, N=nymphs, F=female, M=male; upper row unfed ticks, lower row fully engorged larvae, nymphs and a female; all same scale. Amblyomma species are widespread on domestic animals throughout tropical and subtropical regions.
Argas persicus, also known as fowl tick or poultry tick, is a small soft-bodied tick that is found primarily on domestic fowl such as chickens, ducks, and geese. It was first recorded by Lorenz Oken in 1818 in Mianeh , Persia , [ 1 ] [ 2 ] and named Rhynochoprion persicum .
The life cycle of Ixodes pacificus consists of four life stages: egg, larva, nymph, and adult. It takes approximately three years for the tick to complete its life cycle. [11] Larvae, which emerge from eggs after approximately 53–55 days, take blood meals from vertebrates, such as lizards and birds.
Dermacentor andersoni, commonly known as the Rocky Mountain wood tick, is a hard tick, or member of the Ixodidae family, with three life stages including larvae, nymph, and finally adult, or, more entomologically, imago. This tick is generally located in the northwest United States and southwest Canada along the Rocky Mountains.
The life cycle of the tick was studied chiefly by Ian Clunies Ross. [9] Clunies Ross also demonstrated that a toxin produced by the tick, and not some infective agent carried by the tick, was responsible for the paralysis. [10] [11] The life cycle was further studied by Oxer and Ricardo (1942) [12] and later summarised by Seddon (1968). [13]
Free-roaming individuals of O. coriaceus are most often found near the bedding areas of deer, or in native habitats exposed to grazing by large numbers of cattle or horses. Records of this species come from areas with a range of vegetation types including manzanita and scrub-oak chaparral , mountain-mahogany scrub, among cottonwoods, as well in ...
