Ticks In Colorado

Ixodes ochotonae

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes ochotonae Distribution The geographic distribution of I. ochotonae in the USA includes CA, CO, ID, MT, NV, UT, WA, and WY; in Canada, British Columbia and Saskatchewan. Hosts Hosts include primarily pikas and woodrats, but also chipmunks, pocket gophers, voles, and native mice. Vector Status Anaplasma phagocytophilum DNA has been detected in Ixodes ochotonae ticks from California.

Ixodes sculptus

[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....

Ixodes soricis

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes soricis Distribution This tick occurs in AZ, CA, CO, NM, OR, UT, and WA in the United States; in Canada, British Columbia. Hosts This tick is primarily an ectoparasite of shrews, including at least eight species of Sorex. It also parasitizes other insectivores, such as the broad-footed mole; Townsend’s mole; the shrew mole; and some rodents, such as the northern pocket gopher; graytailed vole; Townsend’s vole; and North American deermouse. There is also a record of it biting a human. Vector Status No reports of medical or veterinary importance for this species has been found to date.

Ixodes spinipalpis

[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 texanus

[vc_row][vc_column width="2/3"][vc_column_text] Ixodes texanus Distribution Distribution in the USA includes AL, AR, AZ, CA, CO, CT, DE, FL GA, IA, ID, IL, IN, KS, LA, MD, MI, MO, MT, NC, NM, NY, OH, OK, OR, SC, TN, TX, UT, VA, WA, WI, and WV; in Canada, British Columbia, Quebec, and Ontario. It is also thought to occur in Mexico, specifically the states of Guerrero and Nuevo Leon. Hosts Hosts include weasels, badgers, skunks, and other mustelid carnivores in western states of the USA, and primarily raccoons in the East. Occasional hosts include Virginia opossums,rodents, lagomorphs; domestic dogs and humans. Vector Status The agents of raccoon babesiosis, ehrlichiosis  and Rocky Mountain spotted fever have been detected from Ixodes texanus.

Ixodes woodi

[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.

Argas cooleyi

[vc_row][vc_column width="2/3"][vc_column_text] Argas cooleyi Distribution In the US, collections of A. cooleyi are reported from CA, CO, MT, NV, TX, UT, WA, WY and possibly OR and SD, although this argasid probably occurs more widely within the geographical range of American cliff swallows, in the arid western states. Argas cooleyi is also reported from Chihuahua, Mexico and from a single collection from the nest of a bluebird, in British Columbia, Canada. Like most argasids, this species is nocturnal and has demonstrated high survival rates during an almost 3-yr absence of hosts. This tick species is not to be confused with Ornithodoros cooleyi, which, until recently, has been referred to under the homonym, Argas cooleyi. This latter species also occurs in the western United States, specifically Arizona and Nevada, but...

Argas radiatus 

[vc_row][vc_column width="2/3"][vc_column_text] Argas radiatus Distribution Earlier collections of A. radiatus originated from FL, IA, TX, and central and northeastern Mexico. In 2012, a female tick was found in a tree-mounted Lindgren funnel, a device designed to collect arboreal insects, Adams Co., CO. Hosts Hosts for A. radiatus are birds, especially domestic poultry, but some collections are known from roosts of other large native birds, such as wild turkey, black vulture, and bald eagle, which may have been its original hosts. Although this tick can complete its life cycle in approximately 2 months as demonstrated in TX, it alternatively can survive unfed for longer than 3 years. Vector Status Argas radiatus can cause host paralysis, especially in domestic fowl, and it is an experimental vector of the rickettsial agent of aegyptianellosis, Aegyptianella pullorum...

Carios concanensis 

[vc_row][vc_column width="2/3"][vc_column_text] Carios concanensis Distribution Carios concanensis occurs in AZ, CA, CO, Kansas, MT, OK, SD, TX, UT, WA, and WY in the United States, and in Alberta and Saskatchewan in Canada. Distribution records for C. concanensis in CO trace primarily to collections reported under the synonym Ornithodoros aquilae. Hosts This tick has been collected from caves in AZ and TX occupied by bats, specifically big brown bat, cave myotis, and Mexican free-tailed bat. Cliff-nesting swallows, are seasonally the most important hosts for C. concanensis. Hosts also include prairie falcons, golden eagles, western red-tailed hawks, and ferruginous pygmy owls. Vector Status C. concanensis has been implicated as a vector of Babesia moskovskii in prairie falcons; attributing deaths of prairie falcon nestlings to heavy infestations.

Carios kelleyi

[vc_row][vc_column width="2/3"][vc_column_text] Carios kelleyi Distribution Carios kelleyi is distributed widely in the United States, with records from AL, AR, AZ, CA, CO, CT, GA, IL, IA, KY, Maryland, MI, MN, MO, MT, (recently NJ), NM, NV, NY, PA, SD, TX, UT, WA, and WI. In Canada, it occurs in AB and SK and in MX, Sonora and Durango. Unlike many species of argasid ticks, C. kelleyi larvae are slow feeders requiring days (9-20) to engorge, which may explain the widespread distribution of this species as it may be easily transported by its host. Hosts This tick usually feeds on bats and is reported from at least five genera of bats in North America, especially Myotis spp. They have been reported to bite humans. Human encounters may occur when bats vacate roosts...
