S. Budak ; S. Quisenberry ; X. Ni | 1999The 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 resistance is an economical management tactic to control D[...]article/chapitre/communication
R. Bowling ; G. Wilde | 1996Three sorghum cultivars resistant to greenbug biotype I (Cargill 607 E, PI550607, and PI550610) were evaluated to determine their mechanisms of resistance. Results indicated antibiosis and antixenosis were mechanisms of resistance in the 3 sorgh[...]article/chapitre/communication
I. Annan ; G. Schaefers ; W. Tingey ; W. Tjallingii | 1997Electrical penetration graph recordings using direct current (DC-EPGs) were used to analyze aspects of the probing behavior of cowpea aphid, Aphis craccivora Koch, on intact plants and on hexane, ethyl acetate, and methanol extracts of leaves of[...]article/chapitre/communication
A. Givovich ; H. Niemeyer | 1995Feeding behaviour of five species of cereal aphids in wheat seedlings differing in hydroxamic acid (Hx) levels, was monitored via electrical penetration graphs (EPG). Aphid species could be grouped as sensitive to the feeding deterrent effect of[...]article/chapitre/communication

D. Hardie ; S. Clement | 2001Laboratory and glasshouse bioassays were developed in Australia and the US for evaluating wild pea (Pisum fulvum Sibth. & Sm.) accessions for resistance to pea weevil (Bruchus pisorum) (L.). one of the most important pests of cultivated pea (Pis[...]article/chapitre/communication
X. Ni ; S. Quisenberry | 1997Five genotypes of wheat, Triticum aestivum L. ('Arapahoe', 'Halt', PI 137739, PI 225245, and PI 262660), were compared for their antixenotic effects on the Russian wheat aphid, Diuraphis noxia (Mordvilko). Comparisons were made by host plant cho[...]
