Oxidative Responses of Resistant and Susceptible Cereal Leaves to Symptomatic and Nonsymptomatic Cereal Aphid (Hemiptera: Aphididae) Feeding
Abstract The impact of the leaf-chlorosis-eliciting Russian wheat aphid, Diuraphis noxia (Mordvilko), and the nonchlorosis-eliciting bird cherry-oat aphid, Rhopalosiphum padi (L.), feeding on D.Expand

Physiological and Growth Tolerance in Wheat to Russian Wheat Aphid (Homoptera: Aphididae) Injury
Plant tolerance to injury from insect herbivores has several advantages as a pest management approach. However, its use is limited because mechanisms conferring plant tolerance are not wellExpand

Fall Armyworm Symposium--1988: Oviposition Preference, Mating Compatibility, and Development of Two Fall Armyworm Strains
Host strains (corn and rice) of the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), were evaluated for oviposition preference, mating compatibility, and development on artificial diet andExpand

Characterization of Oxidative Enzyme Changes in Buffalograsses Challenged by Blissus occiduus
Abstract This research investigated the role of oxidative enzymes in the defense response of buffalograss, Buchloë dactyloides (Nuttall) Engelmann, to Blissus occiduus Barber. Changes in catalase andExpand

Comparison of Chlorophyll and Carotenoid Concentrations Among Russian Wheat Aphid (Homoptera: Aphididae)-Infested Wheat Isolines
Abstract Russian wheat aphid, Diuraphis noxia (Mordvilko), feeding injury on ‘Betta’ wheat isolines with the Dn1 and Dn2 genes was compared by assessing chlorophyll and carotenoid concentrations, andExpand

Pea leaf weevil (Coleoptera: Curculionidae) spatial distribution in peas
The effects of tillage, location within a plot, and date of sampling on the spatial distribution of adult Sitona lineatus (L.) in peas, Pisum sativum L., were evaluated using geostatistical analyses.Expand

Aphid (Hemiptera: Aphididae) resistance in wheat near-isogenic lines.
Plant and aphid biomass, photosynthetic pigment (chlorophylls a and b and carotenoids) concentrations, and chlorophyll a/b and chlorophyll/carotenoid ratios were quantified in aphid-infested 'Tugela'Expand

Comparison of Diuraphis noxia resistance in wheat isolines and plant introduction lines
The Russian wheat aphid, Diuraphis noxia (Mordvilko), is one of the most important aphid pests of wheat, Triticum aestivum L., worldwide. Among the various pest management options, plant resistanceExpand
