Mating disruption by vibrational signals: state of the field and perspectives

Until a few years ago, the concept of mating disruption had been exclusively associated with the use of pheromones to reduce population density of insect pests. Since the early 2000s, a novel approach has been proposed to the scientific community: vibrational mating disruption (VMD). The novelty is the use of disturbance vibrations to disrupt the mating behavior of insect pests that communicate by means of substrate-borne vibrations. This research falls within the new field of biotremology and it brought the VMD from a theoretical concept to practical open field experimentation: in 2017, VMD was applied in an organic vineyard in Northern Italy to control leafhopper pests’ population density. This achievement gave us the opportunity to report the state of the field for the method, to discuss the ongoing research and to make a comparison between pheromone mating disruption (PMD) and VMD. In this chapter, we review the salient moments that led to the field application of VMD. Then, we discuss the VMD characteristics and we provide a benchmark, using as reference the traditional PMD to discuss similarities and differences. Furthermore, we analyze the advantages and disadvantages of applying VMD to commercial crops. We are convinced that the first vibrational vineyard is a starting point and that biotremology will provide many innovative possibilities for farmers to control pests in the future. We also think that the introduction of electronic devices in the vineyard could be a trailblazer for the diffusion of smart technology in viticulture, thus improving its general management.
