“…The presence of R. microplus in dry regions has been reported elsewhere in West Africa (Madder et al, 2007), South Africa (Nyangiwe et al, 2013a;Tonnesen et al, 2004), Zambia (Berkvens et al, 1998), East Africa (Lynen et al, 2008) and more recently in Namibia (Nyangiwe et al, 2013b). However, what is noteworthy is the spread of this tick into the interior of the country.…”

Ticks and Tick-borne Diseases

Tick borne diseases (TBDs) are responsible for huge economic losses in cattle production in most African countries where the majority of cattle owners are the resource poor communal farmers. Governments have initiated and co-ordinate tick control programs with farmers required to contribute funds for their sustenance. The success of these programs will hinge upon the involvement of communal farmers in their design, implementation and evaluation. To this end, 313 communal farmers (approximately 8.4% of the target population) were interviewed and 3 focus group discussions were carried out in the southern low-veld part of Zimbabwe with the objectives of investigating communal farmers" perceptions on TBDs affecting cattle, level of participation in government initiated tick control programs, other tick control methods practiced, types of acaricides used and their perceived effectiveness. There was a general awareness of TBDs with 67.7% (n=212) farmers being able to describe tick diseases with names or clinical and post-mortem signs. The diseases or situations frequently associated with ticks were codwriosis (38%, n=119), mastitis (36.7%, n=115), anaplasmosis (36.1%, n=113), body damage (28.4%, n=89), babesiosis (24.6%, n=77) and poor body condition (16.6%, n=52). Cattle mortalities due to TBDs were reported by 23.8% (n=74) of the farmers. Farmers (40.6% , n=127) reported an increase in the number of cases of TBDs while 53.4% (n=167) did not see an increase. The plunge dip was consistently used by farmers (70.3%, n=220) to control ticks. Other tick control methods practiced were the hand spraying (67.4%, n=211), hand dressing (16.6%, n=52), traditional methods (5.4%, n=17), use of pour-ons (4.5%, n=14) and smearing (2.2%, n=7). The formamidines were the most common class of acaricide used (59.4%, n=186), followed by synthetic pyrethroids (29.1%, n=91), macro cyclic lactones (12.8%, n=40) and organophosphates (4.5%, n=14). Most farmers (75.2%, n=231) perceived these acaricides to be effective in controlling ticks. The results of focus group discussions showed that a number of factors influenced the success of government initiated tick control programs and these included inconsistent supply of acaricides, unaffordable dipping fees, lack of water, long distance to the dip tank, lack of information on dipping procedures and lack of knowledge on strategies for delaying acaricide resistance. This study demonstrates that while farmers can be a valuable source of information with regards to the epidemiology of tick borne diseases affecting their cattle, there is still need for further training in understanding the TBDs and strategies for their control.

“…One might speculate that the shorter life cycle of R. microplus and the tendency towards assortative mating and successful feeding may provide R. microplus an advantage over R. decoloratus. Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern [65]. There thus appears to be a zone of reproductive interference where R. decoloratus and R. microplus overlap in South Africa, but experimental evidence regarding this zone is much too scant to draw any firm conclusions as to the extent to which this zone may either contain or prevent the spread of R. microplus.…”

Ticks are well-known parasites that affect livestock productivity. This paper reviews the current knowledge regarding the spread of ticks with their impact in animal health and the limitations to achieve effective control measures. The forecasted trends in climate play an obvious role in promoting the spread of ticks in several regions. It appears that climate warming is pivotal in the spread and colonization of new territories by Rhipicephalus microplus in several regions of Africa. The reported increase in altitude of this tick species in the mountainous regions of Central and South America appears to be driven by such general trends in climate change. This factor, however, is not the only single contributor to the spread of ticks. The poor management of farms, uncontrolled movements of domestic animals, abundance of wild animals, and absence of an adequate framework to capture the ecological plasticity of certain ticks may explain the complexity of the control measures. In this paper, we review several details regarding the relationships of ticks with the environment, wild fauna and competition with other species of ticks. Our intention is to highlight these relationships with the aim to produce a coherent framework to explore tick ecology and its relationship with animal production systems.

“…Lynen et al (2008) documented the expansion of its distribution in Tanzania at the expense of R. decoloratus compared to that recorded for these ticks by Yeoman and Walker (1967) many years earlier. The first record of R. microplus in West Africa is that of Madder et al (2007), who reported its presence in Ivory Coast. By 2008 it had almost completely displaced the various indigenous Rhipicephalus (Boophilus) spp.…”

Displacement of Rhipicephalus decoloratus by Rhipicephalus microplus (Acari: Ixodidae) in the Eastern Cape Province, South Africa

The objective of the study was to establish to what extent the native tick species Rhipicephalus decoloratus had been displaced by the invasive introduced tick, Rhipicephalus microplus at two communally grazed areas in the Eastern Cape Province, South Africa. To this end ticks were collected monthly from 5 cattle over a period of 2 years and from 10 drag-samples of the vegetation over a period of one year at each locality. Whereas 10 years previously only R. decoloratus and no R. microplus had been recorded in the vicinity of the two sites, R. microplus now comprised the bulk of collections at both.Furthermore, significantly greater numbers of R. microplus were collected from cattle at both localities during the 2 nd year of the survey than during the 1 st (P<0.05 and P<0.01). In addition to 83 instances of intraspecific coupling, there were 17 instances of R. microplus males coupled with R. decoloratus females. Collections made from cattle and goats on 2 farms close to the study sites revealed that R. microplus was present on both host species and that it significantly outnumbered R. decoloratus on one of the farms (P<0.001). R. decoloratus and R. microplus larvae as well as larvae exhibiting characteristics of both species were collected from the vegetation.
