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[...]

J. Sandstrom ; A. Telang ; N. Moran | 190Three aphid species were compared with respect to ability of enhancing the nutritional quality of their host plants. Rhopalosiphum padi, which does not induce macroscopic changes in its host plants, was compared with Schizaphis graminum and Diur[...]

A method was devised for collecting phloem sap from the CAM species Opuntia ficus-indica using severed stylets of a scale insect (Dactylopius opuntiae), for which exudation could continue for up to 5 d. For both basal (planted) cladodes and firs[...]

J. Weibull | 1994The phloem sap content of glutamic acid was determined in EDTA leaf exudate samples from a collection of Hordeum vulgare subsp. spontaneum previously screened for Rhopalosiphum padi resistance. Segregating populations of crosses between subsp. s[...]

J. Sandstrom | 1994The performances of three clones of pea aphids, with different host affiliations, were evaluated on four host plants species and on four artificial diets. The amino acid compositions of the diets mimicked those of the phloem sap of the respectiv[...]

A. Givovich ; J. Sandstrom ; H. Niemeyer ; J. Pettersson | 1994Phloem sap of wheat seedlings differing in whole leaf hydroxamic acid (Hx) concentrations was collected by cutting stylets of feeding aphids. DIMBOA-glucoside was the only Hx-related product found. Concentration of DIMBOA-glucoside in phloem sap[...]
