Sažetak
The beetles Cetonia aurata and Potosia cuprea belonging to the subfamily Cetoniinae (Coleoptera: Cetoniidae) are present in peach orchards in Northern Dalmatia, Ravni kotari region. They are often described as flower pest (Rose chafers, flower beetles), and are throught not to be significant as fruit pests. However, during the last ten years some serious damage to fruit has been observed. Since this damage occurs when the fruits are ripening, insecticides cannot be used. There are no literature data about the amount of the damage or how to monitor the damage. This paper describes our monitoring of the population dynamics of the Cetonia aurata and Potosia cuprea, and the method for calculating the damage to fruit suitable for the orchards in this area.the study was conducted during the spring and summer of the year 2005, 2006 and 2007 in the Ravni kotari region, near the villages of Prkos and Smilčić. We used Csalomon VARb3k funnel traps. We took into consideration the population dynamic of the Cetonia aurata and Potosia cuprea, the determination of the other trapped members of the subfamily Cetoniinae, as well as the damage percentage of each cultivar.
