“…The effects of six VOCs on the two flies were tested by dual choice trap assays, including isoamyl alcohol and five esters with five gradient concentrations. Isoamyl alcohol, which had been reported as VOC composition of raspberry, red wine, yeast and the commercial bait Droskidrink, elicits strong antennal electrophysiological responses in D. suzukii 43–45 . It was attractive to Bactrocera oleae (Diptera: Tephritidae) within concentrations ranging from 1 to 100 μg ml −1 , and could improve the efficiency of yellow sticky traps in field tests 46 .…”

BackgroundBehavior‐based manipulation is an essential part of Drosophila integrated pest management (IPM). Effective compounds are useful for improving the efficiency of baits and the development of attract‐and‐kill or push–pull strategies to manage Drosophila populations. Here, we investigated the olfactory behavior of two Drosophila species, as well as their pupal parasitoid, to volatiles from bananas, for the identification of effective compounds to control fly populations.ResultsThe results showed that overripe bananas were most attractive to both flies, with a higher attraction index (AI) in Drosophila melanogaster than in Drosophila suzukii. The profiles of volatile organic compounds (VOCs) from bananas with three different ripening stages were compared, and six VOCs were selected for behavioral tests. D. suzukii showed significantly different responses to isoamyl alcohol with D. melanogaster. The effects of ethyl butyrate and ethyl isovalerate on the two flies were dose‐dependent, with lower concentrations acting as repellent and higher concentrations acting as attractant. Isoamyl acetate, isoamyl butyrate and isoamyl isovalerate (0.005–0.05% v/v) were attractive to both flies. The parasitoid wasp Pachycrepoidus vindemmiae was repelled by isoamyl alcohol and ethyl butyrate, and attracted by ethyl isovalerate, but showed no significant response to isoamyl acetate, isoamyl butyrate and isoamyl isovalerate at the tested concentration.ConclusionThis study indicated that the behavioral response of Drosophila to the odor of chemical compounds is dose‐dependent. Isoamyl alcohol and isoamyl acetate at certain concentrations could be used as repellents, whereas ethyl isovalerate as an attractant in control strategy design for D. suzukii. © 2023 Society of Chemical Industry.

The Green Revolution has greatly changed agricultural production methods. Agriculture has become more specialized and intensive, and the use of phytopharmaceutical products, including insecticides, has intensified. However, these are harmful to the environment and human health. At the same time, globalization has led to the introduction of alien species (called invasive), whose establishment in Europe has been facilitated by the abundance of nutritive resources and the absence of natural enemies. These observations are particularly true with Drosophila suzukii. This fly is now considered as the main fruit pest in the world. Thus, it is becoming urgent to find alternative control methods to insecticides to counter the economic damage caused by this new pest. However, the development of an integrated pest management approach requires an excellent understanding of the biology and ecology of the species. In this paper, we first present the state of knowledge on the life cycle, host plants and phenology of D. suzukii. The current geographical distribution and the history of invasion of this pest are detailed, before estimating the extent of the economic losses caused. In a second part, the known alternative control methods against D. suzukii are listed: cultural practices, post-harvest treatments, sterile insect releases, uses of natural enemies and behavioral manipulations (visual and olfactory). Finally, in a third part, we will see how these methods can be combined to improve the control of this pest.

The invasion of Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) worldwide has disrupted existing or developing integrated pest management (IPM) programs in soft-skinned fruits. Currently, with a reliance on only broad-spectrum insecticides, there is a critical call for alternative control measures. Behavioural control is one of the pillars of IPM, and, in the present study, it is investigated whether mass trapping could be viable for D. suzukii management. By quantifying trap interference in 4 × 4 replicate trapping grids, an estimate of the attraction radius for a certain attractant and context can be obtained. Traps designed for dry trapping (no drowning solution, but a killing agent inside) and synthetic controlled released experimental lures were tested in a two-year field study. Apple cider vinegar (ACV) was included as a reference bait and trials were performed with 5, 10 and 15 m inter-trap spacings at different seasonal timings. Clear trap interference and, hence, overlapping attraction radii were observed both in spring and summer for both the synthetic lures and ACV. In early spring, ACV shows the most potential for mass trapping, however from June onwards, the experimental dry lures show equal or better results than ACV. Based on our findings, workable trap densities are deemed possible, encouraging further development of mass trapping strategies for the control of D. suzukii.
