Grape phylloxera biotypes are defined by their specific performance on, or preference for, a
particular host (eg, feeding on a particular rootstock). Numerous studies have phenotyped …

Grape phylloxera biotypes exist throughout viticultural regions causing substantial economic
losses. In the past different biotyping assays were employed to determine host adaption and …

Laboratory bioassays were used for rapid initial evaluation of the susceptibilities of 26 grape
rootstocks to the two known California biotypes of grape phylloxera. An indicator of the …

Studies conducted between 2006 and 2012 examined phylloxera survival characteristics on
commonly planted American rootstock species used in Australia. Although there are still …
