Ixodes woodi

Ticks In Colorado

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes woodi The distribution of I. woodi in the USA includes AL, AZ, CA, CO, ID, IN, KS, NC, NM, NV, OK, OR, SC, TX, UT, and WY; in Mexico, the states of Coahuila, Morelos, and Tamaulipas. Hosts Hosts are primarily woodrats, but also other rodents, birds, shrews, and incidentally, humans. Vector Status DNA of the agent of human granulocytic anaplasmosis was isolated in Ixodes woodi ticks in California; although no vector status was demonstrated, it seems likely that this tick is involved in a zoonotic cycle of the agent among woodrats.

Ixodes spinipalpis

October 23, 2020

Ticks In Colorado

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes spinipalpis Distribution This hard tick is a wide ranging species throughout the western US. It verifiably occurs only in the Pacific Coastal and Mountain States and Provinces of the USA and Canada, including CA, CO, ID, MT, NV, OR, SD, UT, WA, Alberta, and British Columbia. Claims of the occurrence of this tick in NM, TX, and Mexico appear to be questionable. Hosts Adult and immature I. spinipalpis feed on numerous species of rodents, lagomorphs (most recently in Boulder County, CO 2018), and sometimes humans, the latter especially in MT, OR, WA, and CA. Immatures also parasitize birds as evidenced by recent collections from migratory birds (song sparrow orange-crowned warbler, gray catbird, Lincoln’s sparrow) sampled in three counties in CO during bird banding efforts by Bird Conservancy...

Ixodes sculptus

Ticks In Colorado

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes sculptus Distribution This tick occurs throughout western North America; occasionally in the east. Distribution of I. sculptus in the USA includes AZ, CA, CO, IA, ID, IL, IN, KS, LA, MI, MN, MT, ND, NE, NM, NV, OK, OR, SD, TX, UT, WA, WI, and WY; in Canada, Alberta, British Columbia, Saskatchewan and Manitoba. It is commonly found in prairie habitats, but may also occur in shrubland and forested habitats. Hosts This tick is most commonly associated with squirrels, usually burrowing mammals, and their predators. A study in Colorado found that hosts include several species of burrowing mammals, especially thirteen-lined ground squirrels (Spermophilus tridecemlineatus). Several species of carnivores, including domestic dogs, cats, as well as rodents, lagomorphs (rabbits) and goats have also been found to host this tick....

Its distribution in the USA includes AZ, CA, CO, IA, ID, KS, MI, MS, MT, NC, ND, NE, NM, NV, OK, OR, SD, TX, UT, and WY; collections in the eastern USA (GA, MD, and OH) are dubious.

Ixodes howelli

October 22, 2020

Ticks In Colorado

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes howelli Distribution The geographic distribution for this little-known species includes at least AK, CA, CO, MT, and TX but, like I. baergi, it may be more widespread. Its presence in Colorado is based on a single nymph collected in Weld County in 1943 from a prairie falcon and identified by Kohls and Ryckman (1962). Hosts Hosts are primarily cliff swallows; but also other birds that may nest nearby, including the gray-crowned rosy finch, the prairie falcon; and the gyrfalcon. Vector Status This tick currently has no known medical or veterinary importance.

Ixodes brunneus

Ticks In Colorado

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes brunneus Distribution I. brunneus is an ectoparasite of avians, migratory passerines in particular, and, because of this strong host association, it can be found in any of the United States. This tick’s known distribution in the US includes Alabama, Arkansas, California, Connecticut, Florida, Georgia, Indiana, Kansas, Massachusetts, Maryland, Missouri, Mississippi, North Carolina, New Jersey, New York, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Wisconsin and Michigan; in Canada it occurs in Manitoba, New Brunswick, and Ontario. We now add Colorado to the US distribution, based on a recent collection by our citizen science partners at Bird Conservancy of the Rockies. On May 17, 2018, one larval stage I. brunneus was collected from an American yellow warbler, Setophaga petechia, in Jefferson County. The specimen has been...
