Résumé
In the current work, a field survey in thirty-two localities in Apulia region and twenty localities in Tunisia was done in order to identify the different species of the genus Orius (Wolff), their presence during the period of the study. In addition to this, we identified the different Thysanoptera species found in table vineyards in Apulia and studied their impact on this agro-ecosystem. F. occidentalis (Pergande) deserved our attention, along with its most important host plants. In Apulia, six Orius spp. were found, four of them common to Tunisia where we reported nine species. In both countries, O. laevigatus (Fieber) was the most abundant, although in Tunisia O. albidipennis (Reuter) was the most distributed. For the most abundant Orius spp. found, with several generations from the winter till the summer, Chrysanthemum coronarium has been the most important herbaceous host plant in both countries especially during the springtime. In Apulia table vine-growing agro-ecosystem, seven Thysanoptera species were found.
