adaptions in the life cycle of dermacentor variabilis (say) and ixodes dammini (spielman, clifford, piesman, and corwin) marginal populations (acari: ixodidae). | both the dermacentor variabilis and ixodes dammini adult diapause seasons are followed by a breeding period. at the edge of the ticks' range, where diapause and breeding occur under adverse climatic conditions, the species still conserves its fixed response for the onset of diapause. as a result, most of the following breeding effort is wasted; the population can only be maintained by an aberrant breeding period during the normal diapause season. when the diapause and breeding periods are suitab ... | 1985 | 3916750 |
first isolation of lyme disease spirochete, borrelia burgdorferi, from blacklegged tick, ixodes scapularis, removed from a bird in nova scotia, canada. | | 1999 | 10726372 |
birds disperse ixodid (acari: ixodidae) and borrelia burgdorferi-infected ticks in canada. | a total of 152 ixodid ticks (acari: ixodidae) consisting of nine species was collected from 82 passerine birds (33 species) in 14 locations in canada from 1996 to 2000. the lyme disease spirochete borrelia burgdorferi johnson, schmidt, hyde, steigerwaldt & brenner was cultured from the nymph of a blacklegged tick, ixodes scapularis say, that had been removed from a common yellowthroat, geothlypis trichas l., from bon portage island, nova scotia. as a result of bird movement, a nymphal i. scapula ... | 2001 | 11476328 |
genetic diversity in ixodes scapularis (acari: ixodidae) from six established populations in canada. | although ixodes scapularis is the most important vector of borrelia burgdorferi sensu stricto, the causative agent of lyme disease in north america, little is known of the genetic diversity in this tick species within the recently established populations in canada. in the present study, 153 i. scapularis adults collected from southern canada were compared genetically using single-strand conformation polymorphism (sscp) analyses in combination with dna sequencing of the mitochondrial 16s rrna gen ... | 2011 | 21890067 |
