The use of substrate-mediated vibrational regeneration to control insect pests is a rapidly growing line of research targeting many problematic species. Among the current control approaches under testing, vibration inhibitor regeneration aimed at preventing feeding and disengages pests from the target area are relatively unmarked. In the experiments involving introduced pests in the New Zealand Orchard, Passion Vine Hopper (PVH; Scolypopa australis), PVH anti-processing factor behavior and alarm call response, and potential use of alarm calls as vibration-based inhibitory stimuli were investigated. Laser Doppler vibrations and video recordings were used to assess the vibrations and behavioral responses of PVH to the presence of predators (Maratus Griseus Jump Spider), by chance, discovers a new female call involved in the rejection of her companion. In our tests, no evidence of vibration alarm calls on the PVH were found. This significantly reduced the speed of general vibration-based signaling, and reduced overall call trends compared to control records. Instead, PVH responded to predator threats with a rapid jump escape response at 87.5% of attacks. We also tested the effectiveness of three suppressed vibration regeneration in driving PVH movement from the source point, and broadband white noise regeneration ranging from 301-688 Hz, resulting in significant movement from the playback source compared to silent control. It turns out that it caused the As a preliminary proof of the concept, we hope that these results will help develop successful vibration suppression in PVH.
