Prevalence and Identification of Livestock Tick by Sex Ratio and Host in Tehran Province. [PDF]

Vet Med Sci
This study identified tick species infesting livestock and poultry in Tehran Province, revealing a female‐biased sex ratio and sheep as the most infested hosts. Rhipicephalus sanguineus sensu lato was the dominant species. These findings underscore the need for host‐targeted tick control to mitigate disease transmission and economic losses.

Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide‐susceptible and resistant strains

Pest Management Science, EarlyView.
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.

Identification of a novel ß-adrenergic octopamine receptor-like gene (ßAOR-like) and increased ATP-binding cassette B10 (ABCB10) expression in a Rhipicephalus microplus cell line derived from acaricide-resistant ticks [PDF]

, 2016
Background: The cattle tick Rhipicephalus (Boophilus) microplus is an economically important parasite of livestock. Effective control of ticks using acaricides is threatened by the emergence of resistance to many existing compounds. Several continuous R.
