Abstract
In this study, 30 plant species belonging to 18 plant families were sampled for thrips (Thysanoptera) and predatory insects. Collections of thrips and predatory bugs were carried out on ornamental plants in parks, home gardens and greenhouses in the Çukurova region of Turkey, mainly Adana Province. Thrips were sampled from ornamental plants at irregular intervals during 2013-2014. A total of 20 Thysanoptera species were recorded. The most notable species present (at least 10% of samples) were, in descending order of abundance, Frankliniella occidentalis (Pergande) and Thrips tabaci Lind. The thrips fauna was dominated by F. occidentalis which was found on 51% of the samples and contributed 81% of all specimens. A total of 5 predatory hemipteran species were recorded. Orius niger (Wollf) (Anthocoridae) was collected in the highest number (250 specimens), accounting for 43% of all individuals. Thrips and beneficial insects (mainly O. niger) were most common on the plant species belonging to the families Asteraceae Lamiaceae and Verbanaceae. On many plant species, the prey/predator ratio was less than 5 thrips per predator, which may indicate that species of thrips are being effectively suppressed by the predatory bugs detected, particularly on ornamental plants grown in open areas.
Özet
Thrips (Thysanoptera) and predatory bugs collections were carried out on ornamentals plants from parks, home gardens and greenhouses in the Çukurova region of Turkey (mainly Adana province). Thrips were sampled from ornamental plants at irregular intervals during 2013-2014. In this study, 30 plant species belonging to 18 plant families were sampled for thrips and predatory insects. A total of 23 Thysanoptera species were recorded. The most notable species present at least % 10 of samples, were in descending order Frankliniella occidentalis (Pergande) Thrips tabaci Lind. The thrips fauna was dominated by F. occidentalis, this thrips being found in 51 % of the samples and consisting 81 of the specimens. A total of 5 predatory hemipterans were recorded. Predatory Anthocoridae species, Orius niger (Wollf) was collected in the highest number (250 specimens), accounting 43% of total individuals. Thrips and and beneficial insects (mainly O. niger) were more common on the plant species belonging to families Asteracea, Lamiaceae and Verbanaceae. On many plant species, the prey / predator rates were less than 5 thrips per predator indicating that thrips species could be affectively suppressed by the predatory bugs detected particularly in ornamental plants grown in open fields.
