| description | The vigor of six grapevine varieties was followed over three consecutive years in order to evaluate and
analyze its impact on the installation and selection of egg laying sites by an invasive bio-aggressor in
Algerian vineyards. The vigor was estimated by weighing the pruning during dormancy period from
December during three years. A total of ten vines were randomly selected along the diagonal of the
plot. Although the distribution of Jacobiasca lybica seems to be slightly in favor of some grape
varieties compared to others, host vigor seems to be one of the major parameters affecting the
repartition and distribution of this pest. The examination of the Principal Component Analysis (PCA)
showed many similarities; group 1 included the less vigorous varieties (namely Cardinal, Syrah and
Muscat of Alexandria), followed by group 2 including the Dattier of Beirut. On the other hand, group 3
with Cabernet Sauvignon and group 4 with Merlot varieties, are considered the most vigorous, but did
not show a correlation between larval infestations and adult populations. Furthermore, from a
numerical point of view, these grape varieties have the highest number of individuals as much as adults
than larvae. In contrast, it was observed a very pronounced adult trend with grape vigor. |
