Drosophila suzukii Matsumura (Diptera: Drosophilidae), also known as the spotted-wing drosophila, is a global pest fly. The degree of infestation of D. suzukii varies greatly among host plants, possibly depending on the physical properties of the fruits. Because some of the physical properties of fruits can only be judged by touching them, D. suzukii may choose to oviposit based on the physical properties of fruits and remote sensory information such as visual cues. Here, we conducted associative learning experiments with artificial substrates consisting of water, cornmeal, fructose, and agarose with different colors and firmness. We assessed associative learning by conditioning flies with combinations of two colors (purple or green) and degrees of firmness (firm or soft), and comparing their choice between the conditioned color and the other color afterward. We demonstrated that D. suzukii had an associative learning ability but it was limited to the association between green and soft. Drosophila suzukii conditioned with green and soft substrate preferred green as the first choice in the test phase. The proximate cause of this asymmetrical associative learning ability is completely unknown, but the pattern of learning coincides with D. suzukii's preference for immature fruits on the tree in nature, possibly to avoid competition with other fruit flies. The associative learning ability of D. suzukii was found to be limited to a certain combination of color and firmness. It suggests that the asymmetrical association of the natural fruit color and physical properties played a role in the evolution of color-specific associative learning ability of D. suzukii.

“…Previous studies in laboratory, semi‐field, or field conditions have shown D. suzukii prefer darker colors, such as red and black (Lee et al., ; Kirkpatrick et al., ; Rice et al., ). This sphere trap color study conducted in raspberry high tunnels shows a similar response to color under field conditions, where red and black sphere traps consistently captured the most wild D. suzukii .…”

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) were trapped in the field using colored plastic sphere traps coated with insect Tangle-trap. Red and black spheres captured significantly more D. suzukii than white spheres. Translucent deli-cup traps deployed in cherry orchards and baited with yeast, the Alpha Scents lure, or the Scentry lure captured significantly more flies than the Tr ec e lure and Suzukii bait; all attractants had poor selectivity for D. suzukii. No-choice evaluations of attractants conducted in field cages corroborated the cherry orchard field study, though translucent deli-cup traps provisioned with the yeast bait captured significantly more flies than those baited with the Alpha Scents lure. Red sphere traps baited with the Scentry lure captured 3-69 more flies than the deli-cup trap baited with the same lure, and 3-49 more flies than the deli-cup trap baited with yeast bait, demonstrating that a trap integrating both visual and olfactory cues is a superior tool for monitoring D. suzukii. Moreover, this simple sticky, dry trap design requires far less labor and maintenance than does a liquid-based deli-cup trap.

“…Attractive chemical and visual stimuli have been identified for D. suzukii , including odor blends from potential food (fermentation products) and oviposition sources (fruit), as well as visual cues that stimulate landing . Management approaches have been attempted, with mixed success, that use attractive stimuli to divert D. suzukii adults to mass trapping devices or to insecticide‐treated ‘attracticidal’ materials where they are captured or dosed with an insecticide before they lay their eggs .…”

BACKGROUND: Drosophila suzukii Matsumura is a serious pest of small fruits that lays its eggs in growing fruit. Current management strategies rely on an unsustainable schedule of foliar applications of chemical insecticides. Alternative approaches to suppressing oviposition are under investigation, such as attract-and-kill and the use of oviposition deterrents. Here, we evaluated two behavioral control approaches in combination as a push-pull strategy using laboratory and field assays. RESULTS:In laboratory caged assays, both an attractive mass trapping device (pull) and an oviposition deterrent (push: 1-octen-3-ol) reduced oviposition by D. suzukii, and the combination of the two (push-pull) resulted in significantly greater reduction than either treatment alone. In field experiments, oviposition reduction was observed in fruit from plots treated with oviposition deterrent (push) or a combination of mass trapping devices and deterrent (push-pull) compared with fruit from control plots. However, oviposition in plots with mass trapping devices (pull) was higher than observed in all other treatments. Additionally, the protection provided by the deterrent in push plots extended to the entire plot rather than just in fruit closest to deterrent dispensers. CONCLUSION: Push-pull treatments negatively affected D. suzukii infestation in both laboratory and field experiments. The reduction in oviposition observed in laboratory experiments was based on the additive effect of push and pull components acting on a finite population, while the reduction observed in field experiments appeared to be mainly based on the effect of pull components. We discuss potential underlying reasons for the discrepancy results and suggest potential improvements.
