A vertical, four-sided vane trap consisting of sticky, yellow-painted cardboard was developed for monitoring the seasonal activity of Psila rosae (F.). These traps were as attractive to P. rosae as the Stevenson yellow-orange bristol-board trap. Vertical traps caught significantly more P. rosae than horizontal ones and catch increased linearly with trap size. Traps placed 5 to 10 cm above the carrot canopy caught significantly more P. rosae than traps at other heights. In commercial carrot fields, P. rosae catches were always greatest at the headland/crop interface. In areas with uniform P. rosae distribution, total catch increased linearly with trap density but the mean numbers per trap were not significantly different. A large variation in P. rosae population levels among fields suggests that growers would benefit most from a monitoring program implemented on the basis of individual fields.
