The defensin gene family expansion in the tick Ixodes scapularis
Developmental & Comparative Immunology, 2011Ixodid ticks transmit a variety of pathogens by blood feeding. Here, we report computational identification of two multigene families of defensin-like peptides (DLPs) in the Ixodes scapularis genome, one corresponding to scapularisin and the other named scasin.

Survival of Ixodes scapularis (Acari: Ixodidae) Exposed to Cold
Journal of Medical Entomology, 1996The 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.

Lyme disease, caused by infection with Borrelia burgdorferi, is the most frequently reported arthropod-borne disease in the United States. To develop a national map of the distribution of the vectors of B. burgdorferi to humans (Ixodes scapularis Say and Ixodes pacificus Cooley & Kohls ticks), we sent questionnaires to acarologists, health officials ...

Xenodiagnosis Using Ixodes scapularis Larval Ticks in Humans
2017Xenodiagnosis 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.

Occurrence of Larval Ixodes scapularis (Acari: Ixodidae) on Tree Trunks
Journal of Medical Entomology, 1996Host-seeking larvae of blacklegged ticks, Ixodes scapularis Say, were found on the trunks of 7 species of trees in a mixed deciduous woodland in Maryland. Where larvae were present around the bases of trees, larvae were found on 45.8% of the tree trucks. Almost 15% of the larvae found on tree trunks were approximately 1-2 m above the ground.

Thermal accumulation and the early development of Ixodes scapularis.
Journal of vector ecology : journal of the Society for Vector Ecology, 2004We examined the relationship between the accumulation of thermal energy and the onset of oviposition and eclosion of the northern deer tick, Ixodes scapularis, and explored the usefulness of comparing degree days (DD) required for larval emergence with area-wide National Weather Service (NWS) data to construct maps indicating where the establishment of
