While semio-chemical repellents are widespread to tackle insect pest, acoustic-based methods seem to be less commun. I only found this example where it has been used as a commercial tool by disrupting with vibrations the mating behaviour of leafhopper Scaphoideus titanus Ball in an Italian vineyard.
Do you know other acoustic-based insect/arthorpod repellents used in agriculture (excluding on-going experiments) that has been shown to be successful?
I have seen this study! Within, they suggest that vibrations which mimic caterpillar munching can help trigger the production of mustard oil in plants, an insect repellent. However, I'd also be curious to know if this knowledge has been put into place on a food production scale. Either at home gardens or commercially.
Additionally, when I used to work on a farm, we had an air gun go off at random intervals. This was enough to scare all but the most persistent birds away from eating the fruits. So I know using sound as pest control is not foreign to farmers.
