Efficacy of three vegetal powders against Sitophilus granarius in stored wheat and the evaluation of their effect on grain parameters

Doses of 5,10,15, 20 and 25 g of three plant powders,Atractylisgummifera rhizome (AGRP), Daphne gnidium (DGP) and Thapsiagarganica (TGP), were added to 100 g of durum wheat to study their insecticidal effect and ability to preserve the agronomic characteristics of stored grains against the attacks o...

Summary:Doses of 5,10,15, 20 and 25 g of three plant powders,Atractylisgummifera rhizome (AGRP), Daphne gnidium (DGP) and Thapsiagarganica (TGP), were added to 100 g of durum wheat to study their insecticidal effect and ability to preserve the agronomic characteristics of stored grains against the attacks of Sitophilus granaries durum wheat pest overa storage period of 6 months inTiaret district. Algeria. Our results showed that AGRP and DGPcaused 100% mortality, andTGP induced 90%. LD 50 and LD 90 values of 7.24, 8.51, 10.71 and12.88, 15.48, 26.91 g/100 g of wheat were recorded respectively with AGRP, DGP and TGP. We observed a highly significant reduction in the number of eggs laid and offspring emergence, a decrease in weight loss and grain damage, anda high germination percentage in the treated grains. The three powders represent a promising alternative against Sitophilusgranarius.
