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.

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

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.

PROSTAGLANDIN IN THE SALIVA OF THE CATTLE TICK BOOPHILUS MICROPLUS
Australian Journal of Experimental Biology and Medical Science, 1976SummaryPrevious studies of saliva from engorged female cattle ticks revealed a component which induced contraction of some isolated smooth muscles. Fractionation and further characterisation have shown that this substance is of the “slow‐reacting” type, but that it is neither a bradykinin nor slow‐reacting substance of anaphylaxis.

Novel vaccination for control of the Babesia vector, Boophilus microplus
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1989An antigen was isolated from the tick gut wall. Antibody to this antigen bound to the tick gut cells when the ticks fed on immunized animals. Gut function in the ticks and tick development were inhibited.

Electrical studies on the feeding of the cattle-tick, Boophilus microplus
Zeitschrift f�r Parasitenkunde, 1971The patterns of feeding activity and salivation of the cattle tick, Boophilus microplus are described. The form of the electrical signal traces is discussed in relation to the structure of the feeding apparatus. For the first six days after attachment female ticks are mainly inactive.

Ticks with Special Emphasis on Boophilus Microplus
1974Man, with his domestic animals, has intruded into many complex host-parasite relationships involving ticks. Indeed, with the exception of the form of Ornithodorus porcinus which feeds almost exclusively on man in the Kenya Highlands (Walton 1962), all of man’s and many of his domestic animals’ contacts with ticks are casual in that wildlife are the ...

Boophilus microplus: Digestion of hemoglobins by the engorged female tick
Experimental Parasitology, 1974Abstract When the cattle tick Boophilus microplus , after dropping from its host, was maintained at 27 C, the digestion of hemoglobins in the gut proceeded at a steady rate and was virtually complete by the 13th day. The rate was essentially the same whether the ticks were strains susceptible (Yeerongpilly) or resistant (Biarra) to organophosphorous
