Bio-Efficacy Of Flavonoid Extracts And Plant Powders Of Two Artemisia Against Tribolium Castaneum (Coleoptera: Tenebrionidae)

Abstract

This study aims to estimate, in laboratory conditions, the insecticidal effect (leaf powders and flavonoid extracts) of two medicinal plants: Artemisia herba-alba and Artemisia campestris against the pest of stored cereals Tribolium castaneum. The treatments were administered by direct contact to adults of T.castaneum. The vegetable powder was tested with five doses 1, 2, 3, 4, 5% and four doses of the flavonoids are tested 10, 30, 60, 80µl. The toxicity of the crude phytopreparations was estimated by evaluation of mortality, LD50, LD95, TL50. All tested products cause total mortality in adults of T. castaneum. A.herb- alba vegetable powder is more active than A. campestris powder. For flavonoid extracts, it is the butaolic fraction which is the most effective.
