Rhipicephalus (Boophilus) microplus
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 ...

Interspecific behavioural interference and range dynamics: current insights and future directions
ABSTRACT Novel biotic interactions in shifting communities play a key role in determining the ability of species' ranges to track suitable habitat. To date, the impact of biotic interactions on range dynamics have predominantly been studied in the context of interactions between different trophic levels or, to a lesser extent, exploitative competition ...

By using molecular tools 12.2% Theileria, 4.7% Babesia, and 1.8% mixed infections were detected. B. Bigemina isolates (MH790974 Sirajganj) T. annulata (LC439356 Sirajganj) are highly conserved species and Theileria sp (LC419995.1 Rangpur) was found as a different genetic clade which may introduced from neighboring India and Myanmar Abstract Background ...

Reassociation kinetics-based approach for partial genome sequencing of the cattle tick, Rhipicephalus (Boophilus) microplus [PDF]
Background: The size and repetitive nature of the Rhipicephalus microplus genome makes obtaining a full genome sequence fiscally and technically problematic. To selectively obtain gene-enriched regions of this tick's genome, Cot filtration was performed,

Evaluation of phytotherapy alternatives for controlling Rhipicephalus (Boophilus) microplus in vitro [PDF]
Abstract The objective of this study was to identify the main chemical components of the essential oil of Cuminum cyminum L. (cumin) and of the fixed oils of Bertholletia excelsa (Brazil nut) and of Helianthus annuus (sunflower seed). As well as testing the three oils and three different commercial synthetic acaricides against engorged females of ...
