Theresistance mechanisms exhibited by the five selected maize varieties against Ostrinia furnacalis [Gueene] or Asian corn borer (ACB) were identified and evaluated in study terms of insects’ percent mortality development. The detached leaf-feeding assay was used experiment laid out Complete Randomized Design (CRD) with 5 treatments replicated three times. Findings among tested ACB, Bt had a hi...

Russian wheat aphid (Diuraphis noxia, Kurdjumov) feeding on susceptible Triticum aestivum L. leads to leaf rolling, chlorosis and plant death - symptoms not present in resistant lines. Although the effects of several D. noxia (Dn) resistance genes are known, none have been isolated or characterized. Wheat varieties expressing different Dn genes exhibit distinct modes of D. noxia resistance, suc...
