Since the first reports of damage by
Drosophila suzukii
, the spotted-wing
Drosophila
(SWD), over a decade ago in Europe, widespread efforts have been made to understand both the ecology and the evolution of this insect pest, especially due to its phylogenetic proximity to one of the original model organisms,
D. melanogaster
. In addition, researchers have sought to find economically viable solutions for the monitoring and management of this agricultural pest, which has now swept across much of Europe, North America and Asia. In a new direction of study, we present an investigation of plant-based chemistry, where we search for natural compounds that are structurally similar to known olfactory cues from parasitoid wasps that in turn are well-described ovipositional avoidance cues for many
Drosophila
species. Here we test 11 plant species across two plant genera,
Nepeta
and
Actinidia
, and while we find iridoid compounds in both, only those odorants from
Actinidia
are noted to be detected by the insect antenna, and in addition, found to be behaviorally active. Moreover, the
Actinidia
extracts resulted in oviposition avoidance when they were added to fruit samples in the laboratory. Thus we propose the possible efficacy of these plants or their extracted chemistry as a novel means for establishing a cost-effective integrated pest management strategy towards the control of this pest fly.
