title: Toxic effects of various solvents against Rhipicephalus (Boophilus) annulatus.
abstract: The current need of identification of a new acaricidal agent which is acceptable to public as environmentally safe is a daring task. Use of herbal acaricides is such an alternative. Most of the herbal extracts or fractions are dissolved in polar or non-polar solvents or detergents before tested for acaricidal activity. The solvent or detergent to be used for dissolving the herbal extract should be of little acaricidal activity. In the present study, experimentations were carried out on adult engorged female ticks to detect the toxicity of different solvents, viz. hexane, petroleum ether, n-butanol, isopropyl alcohol, chloroform, glycerol, ethyl acetate, acetone, ethanol, and methanol. The study revealed that methanol was the least toxic solvent against Rhipicephalus (Boophilus) annulatus.
