Continuous cell lines derived from many of the vectors of tick-borne arboviruses of medical and veterinary importance are now available. Their role as tools in arbovirus research to date is reviewed and their potential application in studies of tick cell responses to virus infection is explored, by comparison with recent progress in understanding mosquito immunity to arbovirus infection. A prel...

A total of 48 springbok, 48 gemsbok, 23 kudus and 6 giraffes were examined for ticks and lice, while 9 Burchell's zebras and 6 Hartmann's mountain zebras were examined only for ticks. Springbok and gemsbok were shot in both the Etosha National Park in the north and the Hardap Nature Reserve in the south of Namibia. All the other animals were shot in the Etosha National Park. A total of 7 ixodid...

The objective of this article was to discuss some aspects of ticks associated with domestic animals in the State of Pernambuco, northeastern Brazil, based on a literature review and present new data obtained from recent tick collections carried out in this northeastern Brazilian state. From August 2007 to June 2008, 1,405 ticks were collected and five species were identified: Amblyomma cajennen...

background: traditionally, morphological features of rhipicephalus (boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. however, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. hence, molecul...

Four acaricides (amitraz, cyfluthrin, permethrin, and pyrethrins) were studied for their efficacy in the rapid killing of Amblyomma americanum, A. cajennense, and A. maculatum (Acari: Ixodidae) and eight acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, permethrin, pyrethrins, and selamectin) for their efficacy in the rapid killing of Rhipicephalus sanguineus (Acari: Ixodidae)....

Coronado A. 2006. Ixodiphagus hookeri Howard, 1907 (Hymenoptera: Encyrtidae) in the brown dog tick Rhipicephalus sanguineus Latreille, 1806 (Acari: Ixodidae) in Venezuela. Entomotropica 21(1):61-64. Nymphs of the ixodid tick Rhipicephalus sanguineus were found naturally infected by the tiny wasp Ixodiphagus hookeri. The parasitism resulted in the death of the host ticks, as cause of ingestion o...

OBJECTIVES Ticks are vectors of several diseases, of which many are zoonosis transmissible to humans. The use of Tephrosia leafs' extract as a low cost acaricide is spreading among farmers in central Kenya. MATERIALS AND METHODS The present study's aim is to inventory endogenous control methods against dogs' ticks among which Rhipicephalus sanguineus, in the Municipality of Abomey-Calavi. Fro...

Ticks were collected at approximately bi-monthly intervals between June 1996 and June 1997 from crested francolins, Francolinus sephaena, and from the vegetation on a mixed cattle and wildlife farm in Limpopo Province, South Africa. The birds were infested with the immature stages of 13 tick species, of which Amblyomma hebraeum, Amblyomma marmoreum and Hyalomma marginatum rufipes were the most ...

Seventy-three nyalas (Tragelaphus angasii) in the Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal were examined for arthropod parasites during 1983 and 1984. In addition, six animals were examined during 1994. Ten ixodid tick species, two louse species and a louse fly species were recovered. The nyalas were good hosts of all stages of development of Boophilus decoloratus, ...
