Abstract

Reliance on vibrational communication in pair-formation characteristic of leafhoppers presents a unique opportunity for mating disruption using acoustic signals. A proof of concept has been developed, targeting the invasive grapevine pest Scaphoideus titanus, a well-known vector of the phytoplasma disease Flavescence dorée, to create a novel method for controlling this disease. We used a simulated intraspecific disturbance signal, which was played back to the animals using a minishaker attached to the substrate, or a loudspeaker placed next to it. We have also tested requirements for efficiency of this technique and its limitations in laboratory and semi-field conditions, focusing particularly on amplitude threshold for behavioural effect, diel activation pattern, and means of transmitting disturbance signals to host plants. Such a technique could enable substituting chemical methods of pest control with a more environment-friendy approach in certain settings, such as vineyards and greenhouses
