Abstract
In the northern areas of Pakistan, the use of
based therapeutics is a common practice. Plants of genus
are known to possess anthelmintic and therapeutic effect. Infections caused by gastrointestinal nematodes are major threat to livestock industry across the world resulting in loss of production and indirect economic losses due to high cost of anthelmintic drugs. Present study was carried out to evaluate
and
effect of
and
on
a parasitic nematode of small ruminants. Methanolic plant extract was tested against three different developmental stages using an egg hatch assay, infective larvae and adult worm motility assay. Different concentrations were used for the bioassays and post exposure mortality was recorded after 8 hr for adult worms and infective larvae, while egg inhibition percentage was observed after 27 hr. A highly significant ability to inhibit the egg hatching (100 %) was recorded for both plant extracts while, the highest activity for adult worm assay and larvicidal assay was 90 % for
. The highest activity for adult motility and larvicidal assay for
was 89 % and 86.6 % respectively. For
trials maximum parentage reduction was 77.0 % for
and 73.6 % for
. It is concluded that selected plant extracts were effective in reducing worm burden in animals.
