AbstractFull Text

Rhipicephalus (Boophilus) microplus infestation is responsible for significant economic losses in cattle industry. The use of acaricides at strategic times and selection of resistant animals can minimize economic losses. This study aimed to determine the anatomical distribution and population...

Abstract

The Rhipicephalus (Boophilus) microplus is the main cattle tick, responsible for large losses in Brazilian cattle. Control of R. (B.) microplus relies almost exclusively on the use of chemicals. But increasingly this species of tick has shown resistance to products used mainly by the poor use of...

Abstract

Inclusion of cattle genetic resistance to ticks in selection programs represents an auxiliary method in strategic control of this parasite. This study was conducted to estimate genetic parameters for cattle tick resistance measured by tick counting on the inner hind legs region (TCHL) and on one...

Abstract

The cattle tick Rhipicephalus microplus causes significant economic losses to cattle production systems and is a main barrier to the introduction of Bos taurus breeds and their crosses in Brazil. These breeds have the genetic potential to generate animals that are more productive, but they are also ...

AbstractFull Text

Rhipicephalus microplus tick is responsible for large economic losses in the national livestock, mainly due to the reduction in the productive performance of cattle, with damages estimated at billions of dollars per year. The tick is not only a haematophagous ectoparasite, but also a vector of...

Abstract

The objective of the present study was to evaluate the performance of Brangus and Nellore cattle in an extensive production system. Sixty growing bulls, 30 of the Brangus and 30 of the Nellore breeds that were naturally infested with Rhipicephalus microplus were subdivided into four groups: control ...

Abstract

Mogiana tick virus (MGTV) is a segmented jingmenvirus isolated in 2011 from cattle ticks in Brazil. Here, we present a complete coding genome sequence for MGTV isolate MGTV/V4/11, including all four segments. MGTV is evolutionarily related to the Jingmen tick virus isolates SY84 and RC27.
