Résumé - Des expériences réalisées en laboratoire ont établi que B persicae est un vecteur de la sharka. Les adultes, aptères ou ailés, ont transmis le virus à de jeunes plants de 2 cultivars de pêcher, GF 305 et Rubira. B persicae pourrait intervenir dans la propagation naturelle de la maladie car il colonise toute l'année les vergers de pêcher, abricotier et prunier.


Abstract - Experimental transmission of plum pox virus by Brachycaudus persicae Passerini. In laboratory experiments B persicae, apterous and alate adults transmitted plum pox virus to seedlings of 2 peach cultivars, GF 305 and Rubira. It is considered that the aphid might participate in the natural spread of plum pox disease because it colonizes peach, apricot and plum orchards throughout the year.


Key words: virus vector / aphid / plum pox virus / peach seedling / experimental transmission

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
