efficacy of iranian isolate of beauveria bassiana against russian wheat aphid diuraphis noxia (mordvilko) (homoptera:aphididae) on the laboratory conditions

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...

an investigation of the efficacy of two iranian isolates of metarhizium anisopliae against russian wheat aphid, diuraphis noxia (hemiptera: aphididae) under laboratory conditions

in this study, the effects of two metarhizium anisopliae isolates, originally obtained from red palm weevil (rhynchophorus ferrugineus) and a beetle (parandra caspica), on adults of russian wheat aphid diuraphis noxia were studied under laboratory coditions. after a determination of the minimum & maximum concentrations, the adults were treated with conidial concentrations of 1×103 to 1×106 coni...

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,...
