Xenodiagnosis Using Ixodes scapularis Larval Ticks in Humans

2017
Xenodiagnosis is the use of a natural vector to detect the presence of an organism, and xenodiagnosis using Ixodes ticks has long been used by entomologists in Lyme disease research to provide evidence of the host's infectious status with Borrelia burgdorferi.

Vitellogenin and Ecdysteroid Titers in Ixodes scapularis during Vitellogenesis

The Journal of Parasitology, 1997
Ecdysteroids are the only hormones unequivocally identified thus far in ticks. We found a positive correlation between ecdysteroid concentration and vitellogenin synthesis in female Ixodes scapularis. Vitellogenin (Vg) synthetic activity was measured by an in vitro assay for Vg, involving incubations of the fat body with 35S-methionine and ...

Tick Artificial Membrane Feeding for Ixodes scapularis.

Journal of visualized experiments : JoVE, 2022
Ticks and their associated diseases are an important topic of study due to their public health and veterinary burden. However, the feeding requirements of ticks during both study and rearing can limit experimental questions or the ability of labs to research ticks and their associated pathogens.

Teratological NymphalIxodes scapularis(Acari: Ixodidae) From Wisconsin

Journal of Medical Entomology, 2015
Abnormalities of physiological development (teratological forms) in ticks are rare. The occurrence of gigantism, dwarfism, gynandromorphs, missing legs, extra legs, and asymmetries is most often reported from lab-reared specimens, but has been observed in field-collected specimens.

Survival of Ixodes scapularis (Acari: Ixodidae) Exposed to Cold

Journal of Medical Entomology, 1996
The cold hardiness of Ixodes scapularis Say unengorged larvae, engorged larvae, unengorged nymphs, engorged nymphs, and unengorged adults was evaluated. Ticks were exposed to cold for 2 or 8 h at a range of temperatures. Likelihood ratio tests and LT50 estimates were used to evaluate cold hardiness.

HOST SELECTION BY BLACKLEGGED TICKS (IXODES SCAPULARIS)

Here, I have broken the blacklegged tick host selection process into discrete stages — from encountering a host to climbing onto a host — to empirically evaluate how juvenile blacklegged ticks select (or perhaps do not select) their hosts. By breaking down the host selection process into discrete stages where ticks may or may not exhibit differential ...
