Additionally, using high-throughput DNA sequencing of the 16S rRNA gene, I have provided the first assessment of the internal bacterial community structure across all developmental stages of this tick species. I found Rickettsia to be the relatively abundant bacterial genus across life stages, ...
Impressive was the rapid response: all non-fed stages could transition quickly, losing water fast (long day), then slow (short day), and back to fast (long day), with only a single day exposure to short or long day conditions. Short days did not improve the tick's dehydration tolerance...
open sections of woods). The abundance model uses count data summed across all life stages (larval encounters, nymphs, and adults) of the blacklegged tick, collected from spring to fall. Therefore, predictions are also only
for unfed, partially fed (11–21 mg) and replete stages, respectively (Fig. 5). These values are similar to those observed in other tick species7,14,30,34,35. Figure 5 Osmotic pressure of hemolymph and saliva secreted by pilocarpine or dopamine treated ticks. Hemolymph was collected ...
2021). In the Midwestern and Northeastern US, the blacklegged tick (Ixodes scapularis) is the vector of the Lyme disease spirochetes (primarily Borrelia burgdorferi sensu stricto, and less frequently Borrelia mayonii) and the white-footed mouse (Peromyscus leucopus), a species of least concern ...
In the western United States, the western blacklegged tick, Ixodes (I.) pacificus Cooley & Kohls, is the primary vector to humans of the Lyme disease spirochete Borrelia burgdorferi sensu stricto (Burgdorfer et al., 1985; Lane et al., 1994). It is also an important vector of Anaplasma ...
For some of these tick species, including members of the Holarctic Ixodes ricinus complex (including I. pacificus, I. persulcatus, I. ricinus, and I. scapularis), the immature stages (larvae and nymphs) often feed on reptiles whereas adults mainly feed on larger mammals, including humans (...
Drag sampling efficiency, the proportion of the estimated population obtained in a single sample, averaged 6.3% among all stages. Efficiency was not significantly different among stages and was independent of tick density within a given life stage. The population estimation techniques employed in this...
pacificus seasonal questing activity, particularly apparent in the juvenile tick stages, in central and southern California relative to observed patterns in Lyme-endemic northwestern California. Notably, the highly truncated period of questing activity of the juvenile stages has important implications for ...
In addition, researchers have reported immature stages of Lyme disease vector ticks (i.e., I. pacificus, I. scapularis, I. spinipalpis) parasitizing songbirds in Alberta [4,19,21], and each of these tick species exhibits vector competency [35]. These epidemiological findings provide sound ...
