Surveillance for hard ticks of public health concern in Illinois: methods, application, and education
… and effective environmental control methods for ticks, prevention of TBDs relies on reducing of tick bites through other methods. These other methods, such as avoiding tick habitat when ticks are active and using personal protective measures when in tick habitats, often rely on tick surveillance …

Hard ticks and tick-borne pathogens of domestic and wild animals in Maswa and Iringa, Tanzania
참진드기는 체표에 기생하는 정지동물로서 다양한 병원체를 매개한다. 알에서 깨어나 유충, 약충, 성충의 순으로 탈피하며, 알을 제외한 모든 충체는 흡혈을 한다. 아프리카 탄자니아는 아프리카에서 세 번째로 가축이 많은 나라며, 대부분이 소이다. 본 연구는 탄자니아 마스와 지역과 이링가 지역의 소와 야생동물에서 참진드기와 참진드기 매개 병원체를 동정했다. 참진드기를 형태학적 특징에 따라 동정하였고, genomic DNA를 추출해 PCR을 이용해 매개 병원체를 검출하였다. 두 지역에서 소와 야생동물에서 Amblyomma 속 참진드기 …

Evidence for the Role of Ecdysteroids in the Genital Sex Pheromone of Two species of Hard Ticks, <i>Dermacentor variabilis</i> (Say) and <i>Dermacentor andersoni</i> Stiles
<p>Neutering of part-fed females virtually eliminated copulatory behavior in <em>Dermacentor variabilis</em> and<em> D. andersoni</em> males. Extracts from the anterior reproductive tracts (ART) of part-fed (7 days) females restored the male copulatory behavior in conspecific neutered females, …

Helping to Resolve Taxonomic Conflicts within the Genus Amblyomma (Acari:Ixodidae) from a Molecular Perspective
… 1908 and of the <em>A. maculatum </em>group of ticks Camicas, 1998. By using different molecular markers, 12SrDNA, 16SrDNA, DL, COI, COII (mitochondrial) and ITS2 (nuclear), I analyzed the systematic relationships between these taxa and their closest relatives. Phylogenetic analyses by maximum …

Molecular Phylogenetic Relationships of North American Dermacentor Ticks Using Mitochondrial Gene Sequences
… is a recently evolved genus of hard ticks (Family Ixodiae) that includes 36 known species worldwide. Despite the importance of <em>Dermacentor</em> species as vectors of human and animal disease, the systematics of the genus remain largely unresolved. This study focuses on …

Abiotic and biotic determinants of tick-borne disease risk in Central Panama
… distributions becomes increasingly urgent. Hard ticks are ectoparasites that typically feed on a vertebrate host once during each of three life stages and transmit pathogens of public health, conservation, and agricultural importance. Tick distributions are strongly influenced by abiotic …
