Rhipicephalus (Boophilus) microplus

2012
Rhipicephalus (Boophilus) microplus Aitken et al. (1958) recorded a few specimens of the southern cattle tick R. (B.) microplus from cattle and sheep in Trinidad. Williams and Gonzalez (1968) observed that Holstein heifers imported into Trinidad from Canada with the intent to develop a dairy industry were exposed to tick-infested pastures and that ...

Toxicity of piperonyl butoxide to Boophilus microplus

Nature, 1974
SYNERGISM studies with the cattle tick Boophilus microplus have been effected by enclosing larvae in packets impregnated with olive oil solutions of the test chemicals and recording mortality after 48 h1,2. In these conditions larvae exposed continuously to 0.4% piperonyl butoxide were apparently unaffected.

Repellent Effects of Encapsulated Carvacrol on the Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

Journal of medical entomology, 2019
Rhipicephalus (Boophilus) microplus (Canestrini) is a problem for livestock production systems, and its control has become challenging due to the selection of tick populations resistant to synthetic chemical acaricides.

Test for Assortative Mating Between Boophilus microplus and Boophilus annulatus (Acari: Ixodidae)

Journal of Medical Entomology, 1992
The closely related cattle ticks, Boophilus microplus (Canestrini) and B. annulatus (Say), were tested for possible assortative mating under conditions designed to mimic those in the field. Patterns in the numbers of the four possible types of matings were generally indicative of a preference for conspecific mates in both species.

Efficacy of winter–spring strategic control against Rhipicephalus (Boophilus) microplus infestations on cattle in an area with ecological conditions highly favourable for the tick in northeast Argentina

Medical and Veterinary Entomology, 2019
This work was performed to test the efficacy of winter–spring control strategies against Rhipicephalus (Boophilus) microplus (Ixodida: Ixodidae) infestations on cattle in the area ecologically most favourable for the development of this tick in Argentina.

Boophilus microplus: Passive Transfer of Resistance in Cattle

The Journal of Parasitology, 1976
Plasma from cattle highly resistant to the tick Boophilus microplus conferred some resistance to unexposed calves. In contrast plasma from hosts of low resistance had no significant effect compared with plasma from unexposed donors.

Efficacy of Azadirachta indica extracts against Boophilus microplus

Parasitology Research, 2008
Extracts were prepared from leaf, bark, and seed of Azadirachta indica, leaf and seed of Prunus persica, bark of Mangifera indica, and leaf of Psidium guajava and were evaluated against Boophilus microplus. Of the eight extracts screened, the extracts prepared from the A.

Life cycle of the southern cattle tick, Rhipicephalus (Boophilus) microplus Canestrini 1888 (Acari: Ixodidae) under laboratory conditions

Systematic and Applied Acarology, 2018
The southern cattle tick, Rhipicephalus (Boophilus) microplus is one of the most important tick species affecting bovine wealth worldwide. Three uninterrupted generations of this species were observed under laboratory conditions (28±3 °C and 80±5% R.H ...

Parthenogenesis in the Cattle Tick, Boophilus microplus

Nature, 1963
ALTHOUGH bisexual reproduction is usual among ticks, there have been reports of parthenogenesis in various species including Amblyomma agamum1, Rhipicephalus bursa2, A. dissimile3, Hyalomma anatolicum4, Ornithodorus moubata5, and Haemaphysalis bispinosa6; but there appears to be no previous record of parthenogenesis in Boophilus microplus.
