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.

Assortative Mating between Boophilus Decoloratus and Boophilus Microplus (Acari: Ixodidae)

Journal of Medical Entomology, 1986
Observation of mixed infestations of Boophilus decoloratus and B. microplus on cattle shows that assortative mating occurs. The result is a smaller number of hybrid matings than is expected from random mating. The finding has relevance to studies of species interactions and to attempts at genetic control.

Boophilus microplus: Cattle antienzymes to larval phosphomonoesterases

Experimental Parasitology, 1980
Abstract Cattle with previous experience in infection with the cattle tick, Boophilus microplus, were shown to have significant levels of antienzymes directed against phosphomonoesterases of Boophilus microplus larvae. Cattle without previous experience in infection do not show any antienzymatic activity.

Functional bovine immunoglobulins in Boophilus microplus hemolymph

Veterinary Parasitology, 1996
The aim of the present work was to quantify the passage of bovine immunoglobulins into the hemolymph of the tick Boophilus microplus during the feeding process and to determine their antibody activity. The knowledge is of paramount importance when vector control or blocking of disease transmission is attempted by vaccination of cattle. Approximately 2%

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.

A thrombin inhibitor from the gut of Boophilus microplus ticks [PDF]

Experimental and Applied Acarology, 2007
A thrombin inhibitor was identified for the first time in the gut of the cattle tick Boophilus microplus. Here we present the partial purification and characterization of this new molecule, which was purified from the gut extract by three chromatographic steps: ion-exchange, gel filtration and affinity chromatography in a thrombin-Sepharose resin.

Molecular Assessment of Anaplasma marginale in Bovine and Rhipicephalus (Boophilus) microplus Tick of Endemic Tribal Belt of Coastal South Gujarat, India

Acta Parasitologica, 2019
This study described the detection, prevalence and phylogeny of Anaplasma marginale in the bovine (cattle and buffaloes) and Rhipicephalus (Boophilus) microplus tick belonged to the tribal area of coastal South Gujarat, India, by amplifying 576 bp of ...

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.
