Boophilus microplus ticks found in West Africa
Experimental and Applied Acarology, 2007Early in 2007, during a small-scale survey of the ticks infesting cattle in Azaguie about 50 km north of Abidjan, Ivory Coast, ticks, belonging to a species which to our knowledge had never been reported in West Africa before, were encountered. Boophilus microplus was the only member of this genus collected from cattle in the area.

Responses of cattle to allergens from Boophilus microplus
International Journal for Parasitology, 1978Abstract Extracts of larvae of the cattle tick, Boophilus microplus , contain two allergens giving immediate hypersensitivity reactions in the skin of cattle which have been exposed to the tick. The partial purification of one of these is described. This, together with the other allergen whose purification has been described previously, was used to ...

Boophilus microplus: Antihistaminic and tranquillizing drugs and cattle resistance
Experimental Parasitology, 1969Abstract A significant increase occurred in the yield of engorged Boophilus microplus (Acarina, Ixodidae) from eight out of twelve continuously infested bovine hosts treated with the antihistaminic promethazine hydrochloride (Phenergan). Using other drugs an increase occurred with only one host out of six.

The innervation of the salivary gland of the tick, Boophilus microplus
Cell and Tissue Research, 1977Salivary of the ixodid tick Boophilus microplus Canestrini are at least partially innervated by a branch of the pedipalpal nerve. Axons containing both large granular and smaller agranular vesicles were observed within the acini associated with all types of secretory cells.

Test for Assortative Mating Between Boophilus microplus and Boophilus annulatus (Acari: Ixodidae)
Journal of Medical Entomology, 1992The 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.

Boophilus microplus tick burdens on grazing cattle in Colombia
Tropical Animal Health and Production, 1984This study was conducted at Carimagua Research Centre in a well-drained savanna area in the eastern plains of Colombia. The objectives were to note the effect of ecological factors on tick burdens, principally the effect of the environment given by four grasses on the seasonal variations of tick populations. Adult female tick counts were carried out on

The mechanism of feeding and salivation in Boophilus microplus (Canestrini, 1887)
Zeitschrift f�r Parasitenkunde, 1971The feeding apparatus of B. microplus is a primary tanned and secondary tanned (sclerotized) cuticular structure with segments of softer untanned cuticle. It begins as a channel between the hypostome and chelicerae and within the capitulum divides to give, ventrally the pharyngeal valve, pharynx and oesophagus and above these, the salivarium and paired

Sporogony and experimental transmission of Babesia equi by Boophilus microplus
Parasitology Research, 1998The development of Babesia equi in salivary glands of adult female Boophilus microplus was observed under a light microscope using semithin sections stained with toluidine blue. Engorged nymphs were obtained from splenectomized foals experimentally infected with B. equi.

Failure of Boophilus microplus to transmit irradiated Babesia bovis
Research in Veterinary Science, 1983Babesia bovis parasites which had either been freshly irradiated or had been reisolated from cattle infected 12 months previously with irradiated organisms were not transmitted transovarially by cattle ticks (Boophilus microplus). The parent unirradiated strain of B bovis was readily transmitted in this manner after being in host cattle for 12 months.

Efficacy of Azadirachta indica extracts against Boophilus microplus
Parasitology Research, 2008Extracts 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.
