article/chapitre/communication
The probing and feeding behaviour of the cabbage aphid, Brevicoryne brassicae (L.), (Homoptera, Aphididae) was studied on several plant species that represented various levels of acceptability: Sinapis alba L. (a permanent host plant), Capsella [...]article/chapitre/communication
E. Prado ; W. Tjallingii | 1994Aphid salivation in sieve elements and phloem sap ingestion were linked to waveforms in the Electrical Penetration Graph (EPG). Non-viruliferous Rhopalosiphum padi (L.) (Hemiptera, Aphididae) on barley yellow dwarf virus (BYDV) infected wheat co[...]article/chapitre/communication
M. Caillaud | 1999Host specialization plays a central role in the diversification of herbivorous insects and yet we know very little about the evolution of this trait. Populations of the pea aphid, Acyrthosiphon pisum (Harris), are specialized and locally adapted[...]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
K. Ponder ; J. Pritchard ; R. Harrington ; J. Bale | 2000Effects of nitrogen deficiency in hydroponically grown barley seedlings (Hordeum vulgare L.) on the development and reproduction of the aphid Rhopalosiphum padi (L.) (Hemiptera: Aphididae) were investigated. Plant growth was significantly reduce[...]article/chapitre/communication
E. Prado ; W. Tjallingii | 1999Probing behaviour of Aphis fabae Scopoli and Rhopalosiphum padi (L.) was tested in different stress situations normally occurring in aphid-plant studies such as interruption of feeding or starvation, transfer to a new plant, and attachment to th[...]article/chapitre/communication
E. Prado ; W. Tjallingii | 1997Probing behaviour as affected by a previous infestation was studied in two aphid species on their respective host plants. Probing behaviour by Aphis fabae (reported to have beneficial effects when living in colonies) and Rhopalosiphum padi (with[...]article/chapitre/communication
M. Sauge ; J. Lacroze ; J. Poessel ; T. Pascal ; J. Kervella | 2002The effect of a previous infestation by the green peach aphid Myzus persicae (Sulzer) on the settling behaviour and reproduction of the same aphid species was investigated in the resistant peach cultivar Rubira, and compared with that observed i[...]article/chapitre/communication
R. Cole | 1994Feeding behaviour of the cabbage aphid, Brevicoryne brassicae, was monitored electronically on two resistant Brassica species, B. fruticulosa and B. spinescens, and compared with a susceptible control B. oleracea var. capitata cv. Offenham Compa[...]article/chapitre/communication
J. Chen ; Y. Rahbe ; B. Delobel ; N. Sauvion ; J. Guillaud ; G. Febvay | 1997In the melon, the Vat (monogenic, dominant) resistance gene governs both an antixenotic reaction to the melon aphid Aphis gossypii Clover (Homoptera, Aphididae) and a resistance to non-persistent virus transmission, restricted to this vector spe[...]article/chapitre/communication
J. Klingler ; G. Powell ; G. Thompson ; R. Isaacs | 1998The feeding behaviour, excretion rate, and life history traits of the cotton-melon aphid, Aphis gossypii (Glover) (Homoptera, Aphididae), were measured on a resistant melon, Cucumis melon L., breeding line, AR 5. The site of resistance detection[...]article/chapitre/communication
M. Sauge ; J. Kervella ; Y. Rahbe | 1998Electrical penetration graphs of Myzus persicae (Sulzer) (Homoptera: Aphididae) feeding behaviour on four resistant and two susceptible genotypes of peach (Prunus persica L. Batsch) and related species showed that resistance was mainly linked to[...]thèse/mémoire
M. Sauge ; Université de Paris 6 (FRA) | 1999article/chapitre/communication
W. Tjallingii ; B. Gabrys | 1999A deviating type of potential drop (pd), i.e. the electrically recorded intracellular punctures during the pathway phase of plant penetration by aphids, is described and discussed. This so-called repetitive pd (R-pd) has been observed in 4 aphid[...]
