“…Minimum temperature increase also results in the extension of suitability into higher altitudes. Elevation is an important limiting factor for I. scapularis populations as it indirectly affects population establishment through its influence on the complex interaction between climate, physical factors, and biota (Schulze, Lakat et al 1984). As a result of increasing temperatures, the model predicts advancement of suitability into the southern Appalachian Mountains.…”

Effect of Climate Change on Lyme Disease Risk in North America

An understanding of the influence of climate change on Ixodes scapularis, the main vector of Lyme disease in North America, is a fundamental component in assessing changes in the spatial distribution of human risk for the disease. We used a climate suitability model of I. scapularis to examine the potential effects of global climate change on future Lyme disease risk in North America. A climatebased logistic model was first used to explain the current distribution of I. scapularis in North America. Climate change scenarios were then applied to extrapolate the model in time and produce forecasts of vector establishment. The spatially modeled relationship between I. scapularis presence and large-scale environmental data generated the current pattern of I. scapularis across North America with an accuracy of 89% (p<0.0001). Extrapolation of the model revealed a significant expansion of I. scapularis north into Canada with an increase in suitable habitat of 213% by the 2080's. Climate change will also result in a retraction of the vector from southern United States, and movement into the central United States. This report predicts the effect of climate change on Lyme disease risk and specifically forecasts the emergence of a tick-borne infectious disease in Canada. Our modeling approach could thus be used to outline where future control strategies and prevention efforts need to be applied.

“…Much of the published research on meteorological inßuences on Ixodes scapularis Say and Amblyomma americanum (L.) relates to geographical distribution (McEnroe 1977, Schulze et al 1984) and survival (Koch 1981, Daniels et al 1989, Stafford 1994, Lindsay et al 1995, Vandyk et al 1996. Goddard (1992) described the effects of several meteorological parameters measured weekly on questing of adults, and the effects of temperature on initiation of activity of I. scapularis adults have been studied in the Þeld (Duffy and Campbell 1994) and laboratory (Clark 1995).…”

The diurnal questing behavior of adult Ixodes scapularis Say and Amblyomma americanum (L.) were monitored in the field to determine whether ticks would be collected with greater frequency during certain times of the day and under certain ambient meteorological conditions. Temperature and relative humidity explained a significant amount of the total variation in tick collections. Although both species were collected during every period, I. scapularis adults tended to quest earlier and later in the day when temperatures were lower and relative humidity higher, whereas A. americanum were collected with greater frequency in late morning and early afternoon during periods of higher temperatures and lower humidity. Questing of I. scapularis adults was observed at temperatures as low as -0.6 degrees C, whereas no adult A. americanum were collected below 4.4 degrees C. The questing temperature threshold for I. scapularis adults observed in this study was below that reported previously. The implications of these temporal activity patterns on the assessment of disease transmission risk and sampling bias are also discussed.

“…Complicating the issue of vector tick control in New Jersey is the fact that the lone star tick, Amblyomma americanum L., temporally and spatially coexists with I. scapularis in the southern half of the State (Schulze et al 1984a(Schulze et al , 1986, marking the northern extent of signiÞcant populations of this species (Schulze et al 1984b, Schulze andBosler 1996). This tick has been implicated in the transmission of agents of human monocytic ehrlichiosis (HME), E. chaffeenensis (Anderson et al 1993, Walker andDumler 1996), Lyme disease-like illness, B. lonestari (Campbell et al 1995, Barbour et al 1996, and possibly Rocky Mountain spotted fever, Rickettsia rickettsii (Cooley andKohls 1944, Burgdorfer 1975).…”

A single application of granular carbaryl approaching the lowest recommended rate to the shrub layer of a forested area in late spring significantly reduced the abundance of Ixodes scapularis Say nymphs throughout their peak activity period, but had little effect on Amblyomma americanum L. nymphs. Factors influencing the efficacy of the application are discussed. The possible explanations for the lack of efficacy of granular carbaryl against A. americanum, including behavior, formulation, and application rate, are discussed.
