| monthly dynamics of ticks (acari:ixodida) infesting n'dama cattle in the republic of guinea. | the occurrence of ixodid ticks on n'dama cattle was studied in the republic of guinea between june 1994 and may 1995. monthly tick collections were performed on 80 animals from 14 villages located in dabola, kouroussa and dinguiraye prefectures. a total of 19,804 ticks was collected and classified using standard taxonomic keys. the following tick species were identified: amblyomma variegatum, hyalomma marginatum rufipes, hyalomma trunctum, hyalomma nitidum, rhipicephalus lunulatus, rhipicephalus ... | 2004 | 15139086 |
| a study of the acaricidal properties of an essential oil extracted from the leaves of ageratum houstonianum. | study on acaricide property of foam soap containing essential oil of ageratum houstonianum leaves was tested on rhipicephalus lunulatus. four doses of the oil (0.00, 0.02, 0.025 and 0.03 microl/g) with four replications for each dose were used in vitro. each replication consisted of 10 ticks in a petri dish with filter paper impregnated uniformly with the foam soap on the bottom. the same four doses in three replications were used in vivo. each replication was made up of 10 naturally ticks infes ... | 2005 | 15740869 |
| ticks associated with the three largest wild ruminant species in southern africa. | the objective of this study was to assess the host status of the three largest southern african wild ruminants, namely giraffes, giraffa camelopardalis, african buffaloes, syncerus caffer, and eland, taurotragus oryx for ixodid ticks. to this end recently acquired unpublished data are added here to already published findings on the tick burdens of these animals, and the total numbers and species of ticks recorded on 12 giraffes, 18 buffaloes and 36 eland are summarized and discussed. twenty-eigh ... | 2007 | 17933365 |
