Abstract
Population fluctuation monitoring of wheat thrips Haplothrips tritici (Kurdjumov, 1912) (Thysanoptera: Phlaeothripidae) was evaluated on the Tosunbey (wheat) and Tarım92 (barley) cultivars by weekly samplings from plant emergence to the harvest season in 2016 and 2017 in Isparta (Center). Adult and nymphal stages of individuals were collected using direct sampling and shake-out methods. In the direct sampling method, the plant was cut from the above-ground part and brought to the laboratory in polyethylene bags. In the shake-out method, thrips individuals were forced to fall into a white container by making 50 strikes (totally) to the plants, were taken into the eppendorf tubes containing 70% alcohol with the help of a mouth aspirator. The thrips nymphal and adults were separated under a stereomicroscope and their presence numbers were recorded. The population of H. tritici (adult, nymph and egg stages) on Tosunbey wheat variety reached to high numbers with 28.77 and 8.85 specimens/ear on June 13 in 2016 and 2017, respectively. The highest numbers on Tarım92 barley variety was recorded as 3.22 and 3.2 specimens/ear on June 13 in 2016 and on May 25 in 2017, respectively. It is thought that the decrease in thrips population density in 2017 may be due to the number of rainy days in 2017 compared to 2016.
