Abstract
Rhipicephalus (Boophilus) microplus
is considered as one of the most widely distributed tick species
ecto-parasitizing on livestock and causes fatal diseases with
significant production loss. To address the problem of controlling
acaricide resistant tick infestations on animals, attention has been
paid to develop eco-friendly phyto-acaricides. The present study was
undertaken to evaluate the comparative anti-tick activities of
commercially available herbal and chemical products with chemically
characterized phyto-formulations developed recently against field ticks
and resistant tick lines of R. (B.) microplus. The chemical product Butox®
Vet was found nearly passive against all the tested resistant tick
lines. However, one of the commercial polyherbal product, Zerokeet®
showed an efficacy (E%) of 41.8-75.4 % ([Formula: see text]) using
recommended dilution (1:2) against field ticks and resistant tick lines.
However, the other commercial product, Erina® EP has very
limited efficacy against all the tested tick. In comparison, the newly
developed phyto-formulation, NBA/13/B/2 and NAC-01 conferred an E% of
82.4-91.3 % ([Formula: see text]) and 62.3-94.6 % ([Formula: see text]),
respectively, against tested resistant ticks. Results indicated higher
marketing potentiality of newly developed formulation in the existing
tick problem scenario.
