A. Vanderwesthuizen ; Z. Pretorius | 1995The effect of Russian wheat aphid (RWA), Diuraphis noxia infestation on protein, free amino acid, free proline, chlorophyll and phenolic contents as well as respiration rate was studied in resistant (cv Tugela-DN) and susceptible (cv Tugela) whe[...]article/chapitre/communication

H. Niemeyer ; J. Jerez | 1997Hydroxamic acids are defensive secondary metabolites in wheat, the most abundant aglucones being DIMBOA and DIBOA, The location of genes coding for the accumulation of hydroxamic acids by wheat (Triticum aestivum L.) seedlings was explored compa[...]article/chapitre/communication

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
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
E. Gianoli | 2000The cereal aphids Rhopalosiphum padi L, and Sitobion avenae (F.) coexist on the same host plant but occupy different ecological niches. R. padi arrives first in the season and reaches its population peak before S, avenae. In addition, R padi pre[...]article/chapitre/communication

A. Givovich ; H. Niemeyer | 1994The feeding behaviour of five cereal aphid species in wheat seedlings (measured by the time taken by an aphid to penetrate the phloem and the time spent in committed pholem ingestion) and their performance (measured as mean relative growth rates[...]article/chapitre/communication
E. Gianoli ; H. Niemeyer | 1997The effects of temperature and photoperiod on accumulation of hydroxamic acids (Hx) in wheat (Triticum aestivum L.) seedlings were evaluated under laboratory conditions. Hx concentrations were significantly higher at higher temperatures. No such[...]article/chapitre/communication
C. Caputo ; A. Barneix | 1997The effect of different N supply on amino acid export to the phloem was studied in young plants of wheat (Triticum aestivum L. cv. Klein Chamaco), using the exudation in EDTA technique. Plants were grown in a growth cabinet in pots with sand, an[...]
