Abstract

AbstractAdults of the blueberry maggot, Rhagoletis mendax Curran, were captured on Pherocon® AM traps and on 8.5 cm tartar red dark sticky spheres from early July to mid-August in lowbush blueberry fields. Spheres captured significantly more (P < 0.05) adults than Pherocon AM traps deployed vertically and at 45 °angles, but did not capture significantly more adults than Pherocon traps deployed above the plants. Immature females were captured more frequently on Pherocon traps whereas mature females and males were captured more frequently on spheres.The use of either type of trap to monitor adult prevalence to determine the time and need for control treatments appears feasible, but will require further study to provide reliable indexes of adult populations for predicting the need for treatments.
