While adult deer ticks are more likely to carry and transmit Borrelia burgdorferi, it is more common for the hard-to-spot nymphal stage to infect humans. The CDC reported over 30,000 new cases of the disease in 2016 alone, the majority of which were contracted in the summer months, which is when ticks are most likely to bite humans. Ixodes scapularis is the main vector of Lyme disease in North America. Deer ticks can be quite numerous and seemingly gregarious.ĭeer tick lifecycle As disease vector Deer tick 3D rendering of a male and female deer tick In the spring, it can be one of the first invertebrates to become active. It can be active after a hard frost, as daytime temperatures can warm it enough to keep it actively searching for a host. Vertical passage (from mother to egg) of Borrelia is uncommon. Transtadial (between tick stages) passage of Borrelia burgdorferi is common. The following spring, the female lays several hundred to a few thousand eggs in clusters. After she is engorged, the tick drops off and overwinters in the leaf litter of the forest floor. Deer are the preferred host of the adult deer tick, but it is also known to feed on small rodents. Deer tick females latch onto a host and drink its blood for 4–5 days. The tick must take a blood meal at each stage before maturing to the next. Ixodes scapularis has a 2-year lifecycle, during which time it passes through three stages: larva, nymph, and adult. In identifying an engorged tick, concentrating on the legs and upper part of the body is helpful. The tick itself is naturally black when unfed. When the deer tick has consumed a blood meal, its abdomen is a light grayish-blue color. scapularis (see photo below) could easily be mistaken for an entirely different tick. However, the abdomen that holds blood is much larger when engorged therefore, an engorged specimen of I. This is natural, since ticks are generally removed immediately upon discovery to minimize the chance of disease. The image shown here-and in fact, most images of Ixodes scapularis that are commonly available-show an adult female that is unengorged, that is, an adult female that has not had a blood meal. especially while the tick is in the larval or nymphal stage. It is also known to parasitize mice, lizards, migratory birds, etc. It is a vector for several diseases of animals, including humans ( Lyme disease, babesiosis, anaplasmosis, Powassan virus disease, etc.) and is known as the deer tick owing to its habit of parasitizing the white-tailed deer. It is a hard-bodied tick found in the eastern and northern Midwest of the United States as well as in southeastern Canada. It was also named Ixodes dammini until it was shown to be the same species in 1993. One new species of tick, for instance, seems to prefer manicured lawns over shady wooded areas, surprising experts.Ixodes scapularis is commonly known as the deer tick or black-legged tick (although some people reserve the latter term for Ixodes pacificus, which is found on the west coast of the US), and in some parts of the US as the bear tick. The developments - new ticks, new pathogens and rising cases of rare diseases - are leading experts to rethink their advice for avoiding tick bites. Other tick species are also becoming more prevalent new species have established themselves in the Bronx and Staten Island. ![]() But new tick-borne pathogens - with names like Bourbon and Heartland virus - have been detected in New York State in recent years, and rare tick-borne illnesses like babesiosis are infecting more people year by year. ![]() Some experts are warning that it could be a particularly bad tick season.įor decades, the main public health threat from ticks in New York has been Lyme disease, transmitted by the blacklegged tick, often called the “deer tick,” which generally picks up the pathogen from rodents. If you end up becoming one of the hundreds of thousands of New Yorkers expected to be bitten by a tick this summer, don’t be surprised.
