B. Gabrys ; W. Tjallingii ; T. Vanbeek | 1997Probing behavior of adult apterous Brevicoryne brassicae (L.) was monitored with the electical penetration graph (EPG) technique on Sinapis alba L. Old, young, and mature leaves, as well as the generally preferred stems were compared with respec[...]

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[...]

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[...]

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[...]

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[...]

A. Urbanska ; W. Tjallingii ; A. Dixon ; B. Leszczynski | 1998Sucrose-agarose gels and sucrose liquid diets were used to study the phenol oxidising enzymes in the salivary secretions of the grain aphid, Sitobion avenae (Fabricius). Activity indicating the presence of two oxidoreductases, polyphenol oxidase[...]

M. Vanhelden ; W. Tjallingii ; A. Teris ; T. Vanbeek | 1994The chemical composition of phloem sap from lettuce, collected by three different methods, was compared. Phloem sap from stylectomy samples contained sucrose and 14 amino acids. Honeydew and EDTA chelation samples showed considerable breakdown o[...]

M. Vanhelden ; W. Tjallingii ; T. Vanbeek | 1994Three methods to collect phloem sap on different lettuce lines were optimized and are described in detail. The success ratio for stylectomy of aphids was over 80% through the combination of a specially designed setup and electrical penetration g[...]
