“…It is important to remark, though, that our findings suggest that the height position of the bait spray could play a role in its effectiveness. It has also been shown that height played a role in trap efficacy in field conditions, where traps suspended at 1 to 1.5 m above the soil captured the highest rate of D. suzukii compared to traps located at ground level and 2 m above the soil [35].…”

Background Foraging behavior in insects is optimised for locating scattered resources in a complex environment. This behavior can be exploited for use in pest control. Inhibition of feeding can protect crops whereas stimulation can increase the uptake of insecticides. For example, the success of a bait spray, depends on either contact or ingestion, and thus on the insect finding it. Methods To develop an effective bait spray against the invasive pest, Drosophila suzukii, we investigated aspects of foraging behavior that influence the likelihood that the pest interacts with the baits, in summer and winter morphotypes. We video-recorded the flies’ approach behavior towards four stimuli in a two-choice experiment on strawberry leaflets. To determine the most effective bait positioning, we also assessed where on plants the pest naturally forages, using a potted raspberry plant under natural environmental conditions. We also studied starvation resistance at 20 °C and 12 °C for both morphs. Results We found that summer morph flies spent similar time on all baits (agar, combi-protec, yeast) whereas winter morphs spent more time on yeast than the other baits. Both morphs showed a preference to feed at the top of our plant’s canopy. Colder temperatures enhanced survival under starvation conditions in both morphs, and mortality was reduced by food treatment. Conclusions These findings on feeding behavior support informed decisions on the type and placement of a bait to increase pest control.
