AB  - An in vitro screening of the effect of whole plant extracts was carried out. Twenty-one indigenous
plant species were extracted in methanol and tried against the most prevalent tick species;
<i>Hyalomma dromederi</i> of camels. Fully engorged female ticks of the same weight were immersed in the different
extracts for 5, 15, 30 and 60 min. Treated ticks were revived and incubated with the control groups for daily
observation of their activity and egg production. While some plant extracts have killing effects after 30-60 min
exposure (<i>Rhanterium epapposum, Achillea fragrantissima and Eragrostis poaeodes</i>) others have stopped
oviposition (<i>Artemisia herba alba, Haloxylon salicornicum, Plantago coronopus, Moltkiopsis ciliate and
Lasiurus hirsutus</i>). Marked reduction of the egg masses associated with delayed oviposition was recorded on
exposure to <i>Lepidium sativum seeds</i> extract. Most of the extracts have reducing effect on the egg mass that can
be attributed to synergistic effect of flavonoids and phenolics. Tannins and non-tannin phenolics, flavonoids,
alkaloids and saponins were determined by a standard methods. Further studies are going on to support such
ant-tick effects of the bioactive components.
