Distribution of Longidorus attenuatus Hooper in Apulian artichoke fields and its relationship with Italian latent virus
AbstractArtichoke (Cynara scolymus L.) is grown in Apulia on about 15,000 ha (i.e. more that 25% of the total acreage in Italy), thus constituting a crop of major economic importance. Traditionally, it used to be cultivated on the coastal vegetable gardens in the vicinity of Bari from where it spread to the provinces of Brindisi and Foggia (Fig. 1). Favourable environmental conditions and availability of irrigation have greatly contributed to the considerable development of the crop in these areas, which are now the leading Apulian districtis in artichoke production (Marzi, 1967). Although artichoke plants, 2.part from a few remarkable exceptions (for a review see: Martelli and Rana, 1973), do not seem to react with clear-cut symptomatological responses to infection by viruses, it is evident that, in Apulia, the health of crops is far from satisfactory.
