Monitoring traps are essential tools for surveying Drosophila suzukii (Matsumura) populations. The standard deli cup trap, a clear 946mL polystyrene deli-cup perforated with 12 0.5cm holes around the rim of the cup, has been used for both “summer” and “winter” morphs of D. suzukii. However, the height of trap placement has not been evaluated for these two morphs. I hypothesized that winter morph D. suzukii would be captured more frequently when traps were placed on the ground. I also evaluated a modified storgard “dome” trap which was designed to capture stored product beetles foraging on the ground. Trap height and design were evaluated in the laboratory with results validated in field trials. My laboratory experiment showed that regardless of trap design, winter morphs were more frequently captured with traps placed on the ground, whereas summer morphs were more frequently captured in traps hung at 1m. During the field trials, the hanging cup traps were the favored trap for wild D. suzukii summer morphs; additionally, traps placed on the ground were favored by wild D. suzukii winter morphs, similar to laboratory findings for both morphs. These experiments showed that summer and winter morph D. suzukii respond differently to height strata. Overall, the morph of D. suzukii being targeted should be the determining factor for where traps should be placed to accurately estimate population levels.
