Knockdown and persistence efficacies of a pour-on containing Amitraz 1% and Cypermethrin 1% and a spray dip containing 12.5% Amitraz were compared. Knock-down and persistence efficacies of the Amitraz spray dip against Rhipicephalus (Boophilus) decoloratus and Amblyomma hebraeum were significantly higher for the duration of the trial than those of the pour-on. In the case of Rhipicephalus apped...

In order to determine the extent of acaricide resistance in the eastern region of the Eastern Cape Province 1-, 2- and 3-host ticks were collected from cattle at 59 dip-tanks over a period of 2 years. These ticks were tested for resistance against 3 compounds, namely amitraz, cypermethrin and chlorfenvinphos. The Shaw Larval Immersion Test detected emerging resistance to amitraz in Rhipicephalu...

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...

The objective of this work was to study the reproductive behavior of two strains of R. (B.) microplus, one wild-caught (Native) and one reference strain (Media Joya) for two years, measuring the reproductive efficiency index (REI) and reproductive aptitude index (RAI). Engorged ticks from each strain were collected monthly from February 2002 to February 2004. These were weighed and kept in the ...

Metarril SP Organic is a product based on the fungus Metarhizium anisopliae, which was developed for controlling agricultural pests. The present study evaluated the effect of Metarril SP Organic plus 10% mineral oil, for controlling Rhipicephalus microplus under field conditions. Three groups were formed: Control group, which received no treatment; Oil control group, which was bathed only with ...

The present research was conducted to find out acaricidal efficacy of methanolic extracts Calotropis gigantea against Rhipicephalus (Boophilus) microplus ticks in Udaipur (Rajasthan). Larval packet Test (LPT) and Adult Immersion (AIT) were used evaluate efficacy. A total four concentrations the extract (12.5%, 25%, 50%, 100%) along with one control group twice replications for each concentratio...

background: the distribution and ecological preferences of ticks of domestic animals in north of iran were studied four times a year from 2002 to 2005. methods: a total of 1720 tick specimens were collected from cattle, sheep and goats from different localities of caspian sea areas consisting of guilan, mazandaran, golestan and ardebil provinces, iran. results: fourteen tick species were identi...

With the objective of evaluating Rhipicephalus (Boophilus) microplus resistance to cipermetrina and amitraz, were collected engorged tick females from cattle on 20 farms on the Santa Catarina Plateau, in southern Brazil, between January of 2004 and May of 2006. Were also received 20 groups of engorged R. (B.) microplus females, collected by cattle farmers requesting acaricidal efficacy (AE) tes...

Abstract Background This review documents the hard tick species that have been reported in Nigeria, their distribution, pathogens transmitted and disease they cause Nigeria; literature considered studies were conducted between 2000 2021. Main body The (Ixodidae) widely present country are those of genera; Amblyomma, Rhipicephalus/Boophilus, Hyalomma, Ixodes, Dermacentor Haemaphysalis among whic...

The effect of commonly used acaricides (amitraz, cypermethrin, deltamethrin, fenvalerate, and flumethrin) on the eggs of Rhipicephalus (Boophilus) microplus collected from Ludhiana, Punjab, was evaluated by egg hatch assay (EHA). The regression graph of probit hatchability and per cent inhibition of hatching (IH%) of eggs was plotted against log values of concentration of various acaricides. Al...
