“…The distribution pattern is similar to that of A. variegatum (Pegram et al 1981). Cattle are the main host of B. decoloratus (Solomon and Kaaya 1996) but it also feeds on goats, sheep and equine. This may be why it happened to be most abundant species in goats and third in sheep in this study.…”

“…The occurrence of this species in and around the study area was also reported by other authors (Ali and de Castro 1993;de Castro 1994;Sileshi 1995). It is widely distributed and common on domestic livestock in Ethiopia (Solomon and Kaaya 1996;Sileshi et al 2007). The tick shows no apparent preference for any particular altitude, rainfall and/or season (Pegram et al 1981).…”

A survey aimed at determining the status of ticks in cattle, sheep and goats in Bedelle district (Southwestern Ethiopia) was carried out from November 2007 to April 2008. Out of the total 330 animals examined, 314 (95.2%) were found to be infested (harbouring of at least a single tick). High rates of infestations were recorded across all three host species. Factors like month of collection, age and sex of host species did not show significant association with infestation rates. A total of 5,507 ticks belonging to three genera (i.e. Amblyomma, Boophilus and Rhipicephalus) were collected during the study period of which six species were identified. The species of ticks encountered comprise of Amblyomma cohaerens (44.1%), Amblyomma variegatum (13.8%), Amblyomma lepidum (1.2%), Boophilus decoloratus (24.9%), Rhipicephalus evertsi evertsi (14.3%) and Rhipicephalus lunulatus (1.7%). As about 86.7% (4,772) of the ticks were collected from cattle, it was recognised that this could be an evidence of host preference where cattle are serving as principal host while sheep and goats serve as alternative hosts. The role of ecological factors and little attention paid by livestock owners for treatment of animals against ticks are suggested to result in the abundance of ticks. Acaricide spraying should be strategically applied to control ticks. Better result could be achieved if an emphasis is being put on spraying cattle. Studies on tick-borne diseases, involvement of wildlife species as well as related factors are recommended as they may provide a valuable basis for designing and launching an all-round control programme in the country.

“…At Abernossa ranch, Arsi breed was found to be highly tick resistant, followed by Boran breed, but Boran X Holstein was the least resistant (Solomon and Kaaya, 1996). Moran et al (1996) also observed that pure Ankole cattle of Burundi were more resistant than Ankole X Holstein.…”

“…This finding agreed with Ali and de Castro (1993) who reported that Horro breed carried fewer total tick burdens than Horro X Holstein. Aragaw (1994), Yohualashet et al (1995) and Solomon and Kaaya (1996) also reported better control of tick burdens in the local zebu than Holstein crosses.…”

The objective of this study was to evaluate total tick burden and resistance differences of local indigenous breeds and Holstein-crosses (50%). Longitudinal study method was employed to assess the mean monthly half-body regions of total tick burdens. The mean monthly half body regions of total tick count on local indigenous cattle and Holstein-crosses (50%) were 75.2 and 201.7, respectively. The monthly mean half-body region of total tick count on the Holstein-crosses (50%) was significantly (p<0.05) higher than that of the indigenous breed throughout the study months. From 4425 collected adult ticks, Boophilus decoloratus (47.50%), Amblyomma gemma (21.06%), Amblyomma variegatum (18.31%), Amblyomma cohaerens (4.97%), Amblyomma lepidum (3.75%), Rhipicephalus evertsi evertsi (2.87%), Rhipicephalus muhsamae (0.79%) and Rhipicephalus guilhoni (0.75%) were the tick species identified in descending order. Among the tick species identified, seasonal variation was observed in four species, namely: A. variegatum, A. gemma, A. lepidum and R. evertsi evertsi. Animal health extension especially on tick control strategy should be in place in order to improve animal productivity.

“…Paramphistomum infection provokes a lower feed conversion, a loss of weight and/or a decrease in milk production that results in economic loss (Rangel-Ruiz et al 2003).Ticks may be controlled using synthetic acaricides (Klafke et al 2006;Li et al 2007;Barré et al 2008;), but these can have undesirable effects on other organisms and the environment. Ultimately, they become ineffective as ticks develop resistance to synthetic chemicals (Solomon and Kaaya 1996;Shiferaw et al 1997;Chagas 2004). Development of resistance to commercial acaricides by parasites has stimulated the search for new control strategies.…”

The present study was based on assessments of the antiparasitic activities to determine the efficacies of leaf hexane, chloroform, ethyl acetate, acetone and methanol extracts of Aegle marmelos (Linn.) Correa ex Roxb, Andrographis lineata Wallich ex Nees., Andrographis paniculata (Burm.f.) Wallich ex Nees., Cocculus hirsutus (L.) Diels, Eclipta prostrata L., and Tagetes erecta L. against the adult cattle tick Haemaphysalis bispinosa Neumann 1897 (Acarina: Ixodidae), the larvae of Rhipicephalus (Boophilus) microplus Canestrini 1887 (Acari: Ixodidae) and sheep fluke Paramphistomum cervi Zeder 1790 (Digenea: Paramphistomatidae). All plant extracts showed moderate toxic effect on parasites after 24 h of exposure; however, the highest parasitic activity was found in leaf ethyl acetate extract of A. lineata, methanol extract of A. marmelos, A. paniculata, and C. hirsutus against H. bispinosa (LC(50) = 395.27, 358.45, 327.21 and 420.50 ppm); ethyl acetate extract of A. paniculata, C. hirsutus, methanol extracts of A. marmelos, A. lineata, and E. prostrata against the larvae of R. microplus (LC(50) = 207.70, 258.61, 134.09, 206.00, and 274.33 ppm); hexane extract of A. lineata, ethyl acetate extract of A. paniculata, E. prostrata, acetone extracts of T. erecta, methanol extracts of A. marmelos and C. hirsutus against P. cervi (LC(50) = 254.23, 451.17, 425.73, 253.60, 542.71, and 360.17 ppm), respectively. The present study is the first report on the veterinary parasitic activity of plant extracts from Southern India.
