The artichoke latent virus was transmitted from infected artichoke, Cynara scolymus L., to garden pea by Myws persicae (Sulzer) and Acyrthosiphon pisum (Harris). M. persicae transmitted the virus at about 10% efficiency after either a 15 or a 3D-sec artificially terminated acquisition probe, but A. pisum transmitted only after a 30-sec probe. The possibility that the stylets of A. pisum did not penetrate until sometime after 15 sec of labial contact was checked by measuring the length of exposed stylets after 15- and 30-sec probes. Both species were found to have exposed stylets after such probes, but more of them had exposed stylets after a 30-sec probe than after a 15-sec probe. Thus transmission efficiency did not appear to be a function of the depth or frequency of stylet penetration.
