Induced resistance in wheat Triticum aestivum L. by chemical- and bio- fertilizers against English aphid Sitobion avenae (Fabricius) (Hemiptera: Aphididae) in greenhouse
International Journal of Tropical Insect Science 40 (4), 1043-1052
Abstract: Wheat, Triticum aestivum L., is damaged by many insect pests including Sitobion avenae (Fabricius) (Hemiptera: Aphididae). Induced host-plant resistance is an important strategy to reduce damage of the cereal aphids. This study evaluated the effects of wheat seed treated with biofertilizers (Biofarm and Probio96) and the leaves treated with micronutrients (Librel Zinc and α-Iron) on biological parameters of the S. avenae in greenhouse conditions. The treatments have effects in the secondary metabolites in wheat leaves. The higher phenol and anthocyanin contents of wheat leaves occur in Biofarm treatment (345.70 and 0.750 mg/mL, respectively). The lower fecundity of S. avenae (5.33 offspring) occurs on plants treated with Biofarm treatment. The net reproductive rate of aphid fed on plants treated with different treatments changes from 1.63 to 29.56 offspring individual^{- 1}, with the lower and higher values on Biofarm and control treatments, respectively. The lower and higher values of intrinsic rate of increase (r) and finite rate of increase (λ) of S. avenae occur on wheat treated with Biofarm (r = 0.018, λ = 1.018 day^{- 1}) and control (r = 0.148, λ = 1.016 day^{- 1}), respectively. The results indicate that treating seed with biofertilizers (Biofarm and Probio96) is an environmentally safe method and could be used to manage S. avenae.
