Abstract
Ticks are ectoparasites
belonging to the phylum Arachnida infesting humans and animals. Besides their
parasitic role, ticks also spread multiple bacterial, viral, and parasitic
diseases because of their vector role. Hyalomma is a major genus of ticks
containing species of zoonotic and pathogenic significance. Control of the ticks
is the primary importance, but chemical acaricides are being avoided because of
resistance and one health-related issue. In this study, acaricidal and repellent
activities of the ethanolic and ethyl acetate extracts of Tobacco (Nicotiana
tabacum) have been evaluated against the ticks of Hyalomma genus.
Each extract was serially diluted to have 1.25, 2.5, 5, and 10% concentrations.
The parameters taken were adult mortality, larval mortality, egg hatchability
and product effectiveness. The results suggested that the ethyl acetate and
ethanolic extracts had statistically comparable (P>0.05) effects on adult
mortality (tick immersion), larval mortality (larval immersion test), egg
hatchability and tick repellency parameters. This research also revealed that
extracts of N. tabacum were also comparable to (P>0.05) standard
medicated control at the highest concentrations. Ethanolic and ethyl acetate
extracts had significantly (P<0.05) different acaricidal effects from the blank
control at 10% concentration. This research suggests that the N. tabacum
can be used as an acaricidal and tick-repellent agent.
