Acaricide resistance mechanisms in Rhipicephalus (Boophilus) microplus Mecanismos de resistência aos acaricidas em Rhipicephalus (Boophilus) microplus
Acaricide resistance has become widespread in countries where cattle ticks, Rhipicephalus (Boophilus) microplus, are a problem. Resistance arises through genetic changes in a cattle tick population that causes modifications to the target site, increased metabolism or sequestration of the acaricide, or reduced ability of the acaricide to penetrate through the outer protective layers of the tick’...
متن کاملMicroarray analysis of acaricide-inducible gene expression in the southern cattle tick, Rhipicephalus (Boophilus) microplus.
Acaricide-inducible differential gene expression was studied in larvae of Rhipicephalus (Boophilus) microplus using a microarray-based approach. The acaricides used were: coumaphos, permethrin, ivermectin, and amitraz. The microarrays contained over 13 000 probes, having been derived from a previously described R. microplus gene index (BmiGI Version 2; Wang et al., 2007). Relative quantitative ...
متن کاملRhipicephalus (Boophilus) microplus resistant to acaricides and ivermectin in cattle farms of Mexico Rhipicephalus (Boophilus) microplus resistentes aos acaricidas e ivermectina nas fazendas de gado do México
Ticks and the diseases they transmit cause great economic losses to livestock in tropical countries. Non-chemical control alternatives include the use of resistant cattle breeds, biological control and vaccines. However, the most widely used method is the application of different chemical classes of acaricides and macrocyclic lactones. Populations of the cattle tick, Rhipicephalus (Boophilus) m...
متن کاملFirst report of the cattle tick Rhipicephalus microplus resistant to ivermectin in Mexico.
Three cattle farms with ticks, Rhipicephalus microplus, thought to be resistant to ivermectin in Yucatan, Mexico were studied (SFDO, SPN, LUADY). Each field-population was collected and tested twice several months apart. The larval immersion test was used on the progeny of collected adult females to test the susceptibility to ivermectin. Dose-mortality regressions, lethal concentrations (LC), t...
متن کاملMast cell counts correlate with Rhipicephalus (Boophilus) microplus tick load in different cattle breeds
The number of dermal mast cells in several European and Zebu cattle breeds was determined and correlated with the tick load. Breeds included European registered and non-registered Holstein, Brown-Swiss and Jersey cows, Zebu (Nelore and Gyr) and crossbred cows with either high or low tick infestations. Animals were naturally infested with Rhipicephalus (Boophilus) microplus and evaluated at regu...
