Different extract of Anabasis setifera were evaluated under lab. conditions for its biological activity against the adult stage of the rice weevil, Sitophilus oryzae (L.) (Fam: Curculionidae) and cowpea beettle, Challosobruchus chinensis L. (Fam: Bruchidae). The ethanolic extract of A.setifera was toxic (>50 % mortality) to both insect species then applied topically at > 30 ug/insect to S.oryzae and > 40 ug /insect to C.chinensis . When applied to wheat, the ethanolic extract was repellent to S.oryzae and C.chinensis. Application of the ethanolic extract to wheat at concentrations of 63 – 500 p.p.m. reduced the hatchabilty of eggs to 79 – 42.0 respectively in case of C.chinensis. On the values were 70% 42 – 59% in case of S.oryzae . Volatile essences from Anabasis setifera used at 0.5 ml/petri dish killed weevils in 3days and completely suppressed population build – up.
