Characterization of resistance components to russian wheat aphid diuraphis noxia (mordvilko) in several wheat (triticum SPP.)genotypes

Evaluation of wheat (triticum SPP.) resistance to the russian wheat aphid (diuraphis noxia mordvilko)

Modeling the effect of Russian wheat aphid, Diuraphis noxia (Mordvilko) and weeds in winter wheat as guide to management

Infocrop, a generic crop growth model was used to simulate the effect of Russian wheat aphid, Diuraphis noxia (Mordvilko) damage on winter wheat at Fort Collins and Akron, Colorado state, USA,. Observed and simulated yield reductions in four experiments over a period of two years were found to be closely related (R = 0.85). The aphid damage mechanisms coupled to the crop growth model could thus...

biological responses of russian wheat aphid, diuraphis noxia (mordvilko) (homoptera: aphididae) to different wheat varieties

in recent years, the russian wheat aphid, has been included worldwidely in the list of the important pests of cereals, particularly wheat plants. in addition to direct serious damage, the aphid is the main vector of barley yellow dwarf, barley mosaic, and sugarcane mosaic viruses. the pest was reported from east azarbaidjan province (iran) a few years ago and it is now widespread in tabriz,...

Components of resistancce to russian wheat aphid diuraphis noxia (kurdjumov)(homoptera : aphidae) in small grains in fars province

Reproduction and Population Dynamics as Biotypic Markers of Russian Wheat Aphid Diuraphis noxia (Kurdjumov)

Russian wheat aphid Diuraphis noxia (Kurdjumov) is widely established in wheat-growing countries where it causes significant economic losses. The development and use of Russian wheat aphid (RWA)-resistant wheat varieties has been constrained by the variation in resident RWA populations and the evolution of virulent biotypes. An experiment was set up at the Kenya Agricultural and Livestock Resea...

Variation between Ethiopian and North American Barley Varieties (Hordeum vulgare) in Response to Russian Wheat Aphid (Diuraphis noxia) populations

The Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae), causes severe damage to barley, Hordeum vulgare L. (Poales: Poaceae), in the highlands of Ethiopia. Little information is available on the control of this pest in Ethiopia. An experiment aimed at evaluating the resistance of barley varieties from the USA to D. noxia populations and determining biotypic variation betwee...
