Abstract
Polyphylla turkmenoglui Petrovitz, 1965 is one of the the most important pests of vineyards in the Aegean Region of Turkey. Larvae of this species feed on the roots of vineyards and in general, the larvaes are found under the soil. For this reason, controlling this pest is very difficult. The adults mostly feed on pines foliage. In the study, the seasonal activity of the adult beetles of P. turkmenoglui was studied via two light traps between May and August in 2016 and 2017 in two vineyard locations in Alaşehir and Sarıgöl districts, Manisa province of Turkey. At the end of the study, 1.552 specimens of P. turkmenoglui were evaluated. Total 362 and 1.190 specimens were collected from the localities in Alaşehir and Sarıgöl, respectively. In spite of the small differences in trapping localities, the number of the specimens belonging to this species increased as of June, reached the highest level in mid-June and early July, and started to decrease after that date. No specimens were collected after the second half of July. In addition, the morphological features of this species, both male and female, were defined and illustrated.
