Abstract

In this research, Oarius grisescens Desbrochers des Loges has been identified for the first time in apricot orchards in the world and the Yalvaç district of Isparta province in Turkey. Field studies were carried out to monitor the presence of adults of Oarius grisescens in apricot orchards, and the type of damage caused and control. As a result of the surveys, O. grisescens adults were found in the root area of apricot trees during the day and became active during the night and fed on the newly emerging shoots. O. grisescens adults started to emerge from the second week of September, that they were present in the nature for approximately 6-7 weeks during September-November, and that they were active on trunks until December when the temperature was appropriate. It was requisite to monitor the pest in apricot orchards by using siliconized fiber traps starting from September and controlling adults before damaging the fruits and buds. O. grisescens can be controlled by mass trapping when the pest density is low. However, since the density of the pest was very high in the years of study, the traps solely could not be sufficient. Therefore, besides siliconized fibers, the pest should be controlled after harvest with an appropriate insecticide in the second week of September when the adults start to emerge
