Effects of destruxin A on Rhipicephalus (Boophilus) microplus ticks (Acari: Ixodidae).
This study evaluated the effects of destruxin A on Rhipicephalus (Boophilus) microplus females, since this toxin is one of the likely causes of high mortality induced by the entomopathogenic fungus Metarhizium anisopliae in arthropods. Ticks were immersed or inoculated with different concentrations of destruxin A. Despite the doses applied, there were no deaths or significant alterations in ovi...
متن کاملDetection and characterization of amitraz resistance in the southern cattle tick, Boophilus microplus (Acari: Ixodidae).
Amitraz, a formamidine acaricide, plays an important role in the control of the southern cattle tick, Boophilus microplus (Canestrini), and other tick species that infest cattle, dogs, and wild animals. Although resistance to amitraz in B. microplus was previously reported in several countries, the actual measurement of the level of amitraz resistance in ticks has been difficult to determine du...
متن کاملBiological Parameters of Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) Fed on Rabbits, Sheep, and Cattle
In order to determine the effect of various hosts on feeding performance of Rhipicephalus (Boophilus) microplus, we used 3 mammalian species as hosts, cattle (Qinchuan), sheep (T an), and rabbits (Japanese white rabbit) for infest-ing ticks. Five hundreds of R. microplus larvae were exposed to each animal (3 animals/host species). Tick recoveries were 11.0%, 0.47%, and 5.5% from cattle, sheep, ...
متن کاملSusceptibility of Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) to pyrethroids and their associations in Pernambuco, Brazil.
The synthetic pyrethroids and their associations have been widely used for controlling Rhipicephalus (Boophilus) microplus. The frequent use of acaricides has been inducing the development of resistance in the tick populations. The aim of this study was to assess the susceptibility of R. (B.) microplus populations to pyrethroids and their associations in the region of Garanhuns, Pernambuco, Bra...
متن کاملCharacterization of permethrin-resistant Boophilus microplus (Acari: Ixodidae) collected from the state of Coahuila, Mexico.
Southern cattle ticks, Boophilus microplus (Canestrini) (Acari: Ixodidae), collected in Coahuila, Mexico, were determined to be resistant to permethrin. Discriminating concentration (DC) tests at the LC99 and 2X the LC99 of susceptible ticks produced 0 and 0.5% mortality, respectively, for permethrin. However, measured mortalities for coumaphos and amitraz acaricides were within the expected ra...
