Descripción: Abstract: Drosophila suzukii (Matsumura), also known as the spotted wing Drosophila (SWD), is a fastspreading polyphagous pest. Native from South-east Asia, it is well known for causing serious damage in soft-skinned fruit due to the puncture made by the enlarged serrated ovipositor of adult females and the subsequent larvae feeding. Currently, the most commonly used approaches to control D. suzukii infestation are the frequent foliar application of synthetic insecticides and non-selective traps. However, these strategies are inefficient to control D. suzukii spread and crop infestation. Through this study, we aimed to evaluate Drosophila suzukii responses to two different types of chemical stimuli (attractive and repulsive) to be implemented as part of a push-pull system. Both, push and pull components were separately evaluated for a better understanding of Drosophila suzukii behavior. As attractive candidates, aggregation pheromones were studied and to evaluate repellent and oviposition deterrent responses, the following chemical candidates: 1-heptanol, 2-heptanol, 1-hexanol, 2-hexanol, delta-undecalactone (dUDL) and propionic acid were tested. Our results suggest that aggregation pheromones influence different D. suzuki females' and males' host choices. Repellence responses were observed in 1-hexanol and 2-hexanol treatments and oviposition deterrence behavior was observed in 1-hexanol as well, but also in 1-heptanol and 2-heptanol treatments. Our results offer new insights into the use of two-choice assays in D. suzukii behavior studies and new knowledge related to the mechanisms underlying these promising push-pull elements.
