The flight phenology of the raspberry cane midge Resseliella (Thomasiniana) theobaldi was monitored over three successive years (2006-2008) in a raspberry orchard of the Fruit Research Institute in Čačak (Serbia), at the Zdravljak site. This was the first time that large white delta traps baited with the raspberry cane midge sex pheromone were used. No insecticides were used during the monitoring period. Throughout the period, over three growing seasons, the midge presence was detected from April-May to September-October. During the three years, there were variations in the numbers of midges caught per trap, as well as those in the total numbers of midges trapped across years and peak numbers per trap. The highest total number (2,419) of midges during the season and the highest number of midges per trap in a sample (729) were recorded in 2007. The earliest maximum catch per trap (729) occurred in 11 May, 2007.
