| ecological studies of adult ixodes scapularis in central mississippi: questing activity in relation to time of year, vegetation type, and meteorologic conditions. | adult ixodes scapularis say were collected weekly during two fall-winter-spring seasons from 1989 to 1991 to assess their temporal and spatial distribution as well as the effects of several meteorologic parameters on questing activity. collections were made in three 0.4-ha sites in central mississippi by flagging vegetation with a white flannel cloth. adult i. scapularis were collected from 25 october through 11 april during the 1989-1990 season and 24 october-1 april in the 1990-1991 season. pe ... | 1992 | 1625300 |
| status of ixodes dammini (acari: ixodidae) in illinois. | ixodes dammini spielman, clifford, piesman & corwin was found for the first time in illinois in november 1987, when two adult females were collected from two deer in jo daviess county in the northwestern corner of the state. in 1988, in a study of six state parks in northern illinois, questing adults and nymphs were encountered in one park in ogle county. during the firearm deer hunt in november 1988, adult female and male ticks were found in several counties, with a high rate of infestation (gr ... | 1990 | 2388231 |
| lyme disease and migrating birds in the saint croix river valley. | during a study of migrating land birds in 1987, we examined over 9,200 individual birds representing 99 species from the saint croix river valley, a lyme disease-endemic area of east central minnesota and northwestern wisconsin. we found that 250 deer tick (ixodes dammini) larvae and nymphs infested 58 birds from 15 migrant species; 56 ticks (22.4%) were positive for the lyme disease spirochete borrelia burgdorferi. five ground-foraging migrant bird species favoring mesic habitats, veery (cathar ... | 1989 | 2782872 |
| borrelia burgdorferi infection surrounding la crosse, wis. | this investigation defined the extent of borrelia burgdorferi infection surrounding la crosse, wis. white-footed mice, peromyscus leucopus or p. maniculatis, were captured from sites in wisconsin, minnesota, and iowa and cultured for b. burgdorferi to define the local boundaries of the midwestern lyme disease area. all foci of b. burgdorferi infection (n1, n2, n3, and n4) were located north of interstate highway 90 except focus s2, which was south of the highway near fort mccoy, wis. the interst ... | 1988 | 3230137 |
| effects of season and area on ectoparasites of white-tailed deer (odocoileus virginianus) in mississippi. | nine species of ectoparasites (4 acari, 2 mallophaga, 1 anoplura, 1 diptera, and 1 siphonaptera) were recovered from 126 white-tailed deer collected in northern, central, and southern mississippi. intensity and prevalence of adults of ixodes scapularis and larvae, nymphs, and adults of amblyomma americanum varied significantly over collection periods, but not between host sexes. lipoptena mazamae occurred on deer from only one study area. although individual deer were heavily parasitized by tric ... | 1987 | 3586204 |
| ecological studies of ixodes scapularis (acari: ixodidae) in central mississippi: lateral movement of adult ticks. | lateral movement by adult ixodes scapularis say was measured by two mark-release-recapture studies in which ticks were collected by flagging, marked with tiny drops of model paint, released at predetermined spots within the study site, and subsequently recaptured during weekly sampling by flagging. in the first mark-release-recapture experiment, 10/23 ticks were recaptured; all but 3 (2 collected at 3 m and 1 at 1 m) were collected at the release point. in the second experiment, 43/82 ticks were ... | 1993 | 8360912 |
| survey of ticks collected in mississippi for rickettsia, ehrlichia, and borrelia species. | from november 1999 through october 2000, we tested ticks collected from vegetation as well as from deer, dogs, and humans for spotted fever group (sfg) rickettsiae, ehrlichia chaffeensis, and borrelia spp. spirochetes. a total of 149 adult ticks representing four species was collected from 11 collection sites from southwestern to northern mississippi. amblyomma americanum was most commonly collected (n=68), followed by ixodes scapularis (n=53). the bird tick, ixodes brunneus (usually rare), was ... | 2003 | 14714667 |
| geographic distribution of ticks (acari: ixodidae) in iowa with emphasis on ixodes scapularis and their infection with borrelia burgdorferi. | in iowa, public concern regarding lyme disease has increased markedly over the last decade. in response to these concerns, a statewide surveillance program was initiated in 1990 based on ticks received by the department of entomology at iowa state university. ticks were received from health care professionals, state government agencies, and the general public. a total of 5,343 ticks from all 99 iowa counties were identified during the 12 years of this study. dermacentor variabilis was the most n ... | 2005 | 16187889 |

| estimating populations of adult ixodes scapularis in mississippi using a sequential bayesian algorithm. | a sequential bayesian algorithm and accompanying computer program were developed and validated to estimate population numbers of adult blacklegged tick, ixodes scapularis say, using mark-release-recapture methodology in field plots in central mississippi. in fieldwork, data taken in february 2005 in a 1-ha plot yielded an estimate of 317 adult i. scapularis per ha data from another field plot in 2006, 3 km away, yielded an estimate of 280 adult i. scapularis per ha the number of ticks collected ... | 2008 | 18533452 |
