MOLECULAR METHODS FOR DETECTION AND QUANTITATION OF VIRUS IN APHIDS.

Following the introduction of a hitherto uncommon or wholly novel virus into a crop it is necessary to do three things: to identify the target, to manage spread, and (ideally) to eliminate sources of inoculum. Here, we have contrasted a number of approaches that have value for these purposes. In any geographic region (whether "developing" or "developed") it is crucial to be prepared for the unexpected and to have developed a range of technologies that enable these objectives to be addressed.
