Installation of baited Pherocon AM traps for monitoring adult populations of Rhagoletis mendax (Diptera: Tephritidae) in lowbush blueberry fields.
Pherocon AM traps baited with protein hydrolysate and ammonium acetate were evaluated to determine the effect of trap orientation and location on captures of adults of Rhagoletis mendax in lowbush blueberry fields in Nova Scotia, New Brunswick and Maine. Traps that were folded to form a 45° angle with the apex pointing downwards captured significantly more insects than those with the apex pointing upwards. In each case, the baited sticky yellow surface was facing the ground, but was most visible to flies when the apex was pointing downwards. The location of traps between or above blueberry plants did not significantly affect the level of captures.
