![]() ![]() Place sealed specimen(s) and submission form in envelope and mail to: Minnesota Department of Health Vectorborne Diseases Unit 625 North Robert Street P. Copy, scan, or take a picture of this submission form for your records. This information may aid in communicating the seasonality of acarological risk for those living in Minnesota and other upper midwestern states as well as being relevant to the assessment of the ecoepidemiology of Lyme disease and the modeling of transmission dynamics. Fill out one specimen submission form for each person/animal that ticks were collected from and attach with specimen(s). scapularis at least from April through November. The observed nymphal peak corresponded with the typical peak in reported human Lyme disease and anaplasmosis cases.These findings are consistent with previous studies from the Upper Midwest and highlight a risk of human exposure to I. This tick can be found on humans, birds, small and large wildlife, and livestock. CHARACTERISTICS: The lone star tick is an aggressive biter and is not particular when seeking hosts. It can spread diseases like ehrlichiosis and tularemia. Nymphs were most active from May through August, with continuing low-level activity in October, and peak activity most commonly observed in June. The lone star tick is most commonly found in southern states, and has been rarely found in Minnesota. ![]() Adults were active throughout our entire 8-month collection season, with sporadic activity during the summer, larger peaks in activity observed in April, and less consistent and lower peaks observed in October. We conducted biweekly drag sampling across 4 woodland sites in Minnesota between April and November from 2015 to 2017.The majority of ticks collected were I. ![]() Phenology has been well-studied in northeastern states, but not in the Upper Midwest. The incidence of Lyme disease is growing rapidly in upper midwestern states, particularly Michigan, Minnesota, and Wisconsin.The probability of a tick bite, acarological risk, is affected by the phenology of host-seeking I. As the primary vector of Lyme disease spirochetes and several other medically significant pathogens, Ixodes scapularis presents a threat to public health in the United States. ![]()
