Responses of cattle to allergens from Boophilus microplus

International Journal for Parasitology, 1978
Abstract 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 ...

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.

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 ...

Boophilus microplus: Antihistaminic and tranquillizing drugs and cattle resistance

Experimental Parasitology, 1969
Abstract 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.

Distribution of catecholamines in the cattle tick Boophilus microplus

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1977
Abstract 1. The distribution of monoaminergic neurones in the synganglion and peripheral nervous system of the cattle tick Boophilus microplus was studied by the Falck-Hillarp histofluorescence method. 2. Fluorescent cortical cell bodies were associated with the pedal and opisthosomal ganglia and with the stomodeal pons and varicosities in the ...

Boophilus microplus: Strain differences of the cholinesterase system

Experimental Parasitology, 1978
Abstract Cholinesterase (EC 31.1.7 and EC 31.1.8) activity was determined for homogenates of two Argentinian strains of larval ticks, Boophilus microplus . One strain (strain A) was sensitive to organophosphate acaricides. The other strain (strain G) was insensitive to coumaphos and to a lesser degree to other 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.

The innervation of the salivary gland of the tick, Boophilus microplus

Cell and Tissue Research, 1977
Salivary 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.

PROSTAGLANDIN IN THE SALIVA OF THE CATTLE TICK BOOPHILUS MICROPLUS

Australian Journal of Experimental Biology and Medical Science, 1976
SummaryPrevious 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.
