Cloning and molecular analysis of voraxin-α gene of Rhipicephalus (Boophilus) microplus [PDF]

Journal of Parasitic Diseases, 2014
To identify suitable targets for development of cross-protective tick vaccine, in silico analysis was attempted and male tick derived molecule, voraxin-α was targeted. The voraxin-α homologue of Rhipicephalus (Boophilus) microplus was cloned, sequenced and analyzed employing standard methods.

Effect of various acaricides on hatchability of eggs of Rhipicephalus (Boophilus) microplus. [PDF]

Biomed Res Int, 2014
The effect of commonly used acaricides (amitraz, cypermethrin, deltamethrin, fenvalerate, and flumethrin) on the eggs ofRhipicephalus (Boophilus) micropluscollected from Ludhiana, Punjab, was evaluated by egg hatch assay (EHA). The regression graph of probit hatchability and per cent inhibition of hatching (IH%) of eggs was plotted against log values ...
