“…We identified five tick species of public health importance. Previous studies conducted at sites near, and including some of our sites, have identified much the same set of species [4,10,[17][18][19]. Amblyomma americanum was the most abundant, comprising approximately 97% of all individual ticks collected.…”

“…Biweekly sites were selected on feasibility for frequent and year-round sample collection. The data from the Payne site for A. americanum have been reported previously [18]. In this analysis, however, we report on other tick species which were identified at that site, evaluate phenological patterns across the broader two-state region, and use A. americanum to draw comparisons with the other sites.…”

“…A few previous studies have tracked the phenology of ticks in the central Great Plains (e.g., in Kansas, Oklahoma, and Missouri) over the past 10 years [ 10 , 14 – 17 ]. Recent studies in southeastern Kansas, and the Flint Hills region of eastern Kansas and north-central Oklahoma, evaluated seasonality and diversity of tick species in the area [ 4 , 10 , 18 ]. The most common and broadly distributed tick species were A .…”

The states of Kansas and Oklahoma, in the central Great Plains, lie at the western periphery of the geographic distributions of several tick species. As the focus of most research on ticks and tick-borne diseases has been on Lyme disease which commonly occurs in areas to the north and east, the ticks of this region have seen little research attention. Here, we report on the phenology and activity patterns shown by tick species observed at 10 sites across the two states and explore factors associated with abundance of all and life specific individuals of the dominant species. Ticks were collected in 2020–2022 using dragging, flagging and carbon-dioxide trapping techniques, designed to detect questing ticks. The dominant species was A. americanum (24098, 97%) followed by Dermacentor variabilis (370, 2%), D. albipictus (271, 1%), Ixodes scapularis (91, <1%) and A. maculatum (38, <1%). Amblyomma americanum, A. maculatum and D. variabilis were active in Spring and Summer, while D. albipictus and I. scapularis were active in Fall and Winter. Factors associated with numbers of individuals of A. americanum included day of year, habitat, and latitude. Similar associations were observed when abundance was examined by life-stage. Overall, the picture is one of broadly distributed tick species that shows seasonal limitations in the timing of their questing activity.

Ticks represent important vectors of a number of bacterial and viral disease agents, owing to their hematophagous nature and their questing behavior (the process in which they seek new hosts). Questing activity is notably seasonal with spatiotemporal dynamics that needs to be understood in detail as part of mediating and mitigating tick-borne disease risk. Models of the geography of tick questing activity developed to date, however, have ignored the temporal dimensions of that behavior; more fundamentally, they have often not considered the sampling underlying available occurrence data. Here, we have addressed these shortfalls for Amblyomma americanum, the most commonly encountered tick in the central Great Plains, via (1) detailed, longitudinal sampling to characterize the spatiotemporal dimensions of tick questing activity; (2) randomization tests to establish in which environmental dimensions a species is manifesting selective use; and (3) modeling methods that include both presence data and absence data, taking fullest advantage of the information available in the data resource. The outcome was a detailed picture of geographic and temporal variation in suitability for the species through the two-year course of this study. Such models that take full advantage of available information will be crucial in understanding the risk of tick-borne disease into the future.
