, Distribution of Artichoke Italian Latent Virus and Its Nematode Vector in Apulia,rvey show that AILV prevails in the Bari area, occurring in more than 70% of the sampled fields (Table 1).

Electron microscopy studies have been extended to include several non vector species to see if any differences exist between them and the vector species that could be associated with the ability to transmit viruses.

This example is given here only to consider with some care the doubts that are given on the validity of some species because they were “never found since their description”.
