PLANT RESISTANCE Plant Responses to Seven Russian Wheat Aphid (Hemiptera: Aphididae) Biotypes Found in the United States
The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is a serious wheat, Triticum aestivum L., and barley, Hordeum vulgare L., pest throughout the small grain-producing areas in the western United States. The virulency and classiÞcation of recently described Russian wheat aphid biotypes 1Ð7 (RWA1Ð7) were clariÞed using 24 plant differentials. These seven biotypes had bee...
متن کاملDistribution and diversity of russian wheat aphid (Hemiptera: Aphididae) biotypes in North America.
Wheat, Triticum aestivum L., with Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) resistance based on the Dn4 gene has been important in managing Russian wheat aphid since 1994. Recently, five biotypes (RWA1-RWA5) of this aphid have been described based on their ability to differentially damage RWA resistance genes in wheat. RWA2, RWA4, and RWA5 are of great concern beca...
متن کاملSalivary proteins of Russian wheat aphid (Hemiptera: Aphididae).
Salivary secretions play critical roles in aphid-host plant interactions and are responsible for damage associated with aphid feeding. The objectives of this study were to evaluate aspects of salivation and the salivary constituents of Diuraphis noxia (Hemiptera: Aphididae). Salivary proteins were isolated and compared from three aphid probed diets: pure water, 15% sucrose, or amino acids (100 ...

متن کاملPLANT RESISTANCE Limited Genetic Variation Within and Between Russian Wheat Aphid (Hemiptera: Aphididae) Biotypes in the United States
Insect biotypes are populations able to kill or injure crops with resistance genes and complicate pest management programs based on host plant resistance. Biotypes occur in Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), a worldwide pest of wheat, Triticum aestivum L., and barley, Hordeum vulgare L., that was introduced into Mexico in 1980 and then spread into Texas by ...
