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.
