INTRASPECIFIC VARIABILITY IN GRAPE PHYLLOXERA (DAKTULOSPHAIRA VITIFOLIAE FITCH) IN FRANCE: DEVELOPMENT OF REARING TECHNIQUES |
| Authors: | M. Yvon, F. Leclant |
| Keywords: | Rootstock, phylloxera, biotypes, virulence |
| Abstract:
In order to characterize virulence levels of phylloxera biotypes, and predict situations where the aphid could sidestep the resistance of some rootstocks, different techniques have been developed, based on laboratory tests on root cuttings or glasshouse tests with whole grape plants. | |
