“…Leafhoppers rely on substrate‐borne vibrations to identify and locate mating partners. A rival male intercepting a conspecific signal can employ different strategies to disrupt courtship and increase his chances of mating: alternation of male calls, production of rivalry signals that mask the female reply, silently approaching the duetting female and assuming the mating role of the first male (i.e. satellite behavior), and mimicry of the female signals .…”

Background The green leafhopper, Empoasca vitis, is a polyphagous pest of grapevine and tea plants. To date population density is controlled primarily by insecticides and there is a demand for more sustainable controls. To develop a vibrational mating disruption method, the natural occurrence of a ‘disruptive signal’ was investigated. Further, the efficacy of natural and artificial ‘disruptive signals’ was determined. Results With behavioral trials we described male rivalry and recorded a species‐specific disruptive signal (DP). The DP, a single pulse overlapping the competitor male call, interfered with the rival's ability to locate the female. Laboratory playback disruption trials revealed that the pair formation process was prevented by artificial disturbance noises that included the following features: E. vitis DP, Scaphoideus titanus disturbance noise, and a pure tone (250 Hz). Among these, the pure tone was most efficient at preventing mating. Conclusion Results support development of a vibrational mating disruption method as a control strategy for E. vitis. To simultaneously disrupt the mating of E. vitis and S. titanus, the possibility of applying the S. titanus disturbance noise combined with the pure tone is discussed. © 2018 Society of Chemical Industry

“…A few studies on other leafhopper species have reported changes in behavior under changing light conditions. In Graminella nigrifrons , the males oriented toward light when searching for mates [26]. Dalbulus maidis displays more phototaxis to 560 nm than any other wavelength [27].…”

Adult Tea Green Leafhoppers, Empoasca onukii (Matsuda), Change Behaviors under Varying Light Conditions

Insect behaviors are often influenced by light conditions including photoperiod, light intensity, and wavelength. Understanding pest insect responses to changing light conditions may help with developing alternative strategies for pest control. Little is known about the behavioral responses of leafhoppers (Hemiptera: Cicadellidae) to light conditions. The behavior of the tea green leafhopper, Empoasca onukii Matsuda, was examined when exposed to different light photoperiods or wavelengths. Observations included the frequency of locomotion and cleaning activities, and the duration of time spent searching. The results suggested that under normal photoperiod both female and male adults were generally more active in darkness (i.e., at night) than in light. In continuous darkness (DD), the locomotion and cleaning events in Period 1 (7:00–19:00) were significantly increased, when compared to the leafhoppers under normal photoperiod (LD). Leafhoppers, especially females, changed their behavioral patterns to a two day cycle under DD. Under continuous illumination (continuous quartz lamp light, yellow light at night, and green light at night), the activities of locomotion, cleaning, and searching were significantly suppressed during the night (19:00–7:00) and locomotion activities of both females and males were significantly increased during the day (7:00–19:00), suggesting a shift in circadian rhythm. Our work suggests that changes in light conditions, including photoperiod and wavelength, can influence behavioral activities of leafhoppers, potentially affecting other life history traits such as reproduction and development, and may serve as a method for leafhopper behavioral control.

“…In addition, it is likely that male-female duet is vulnerable also to eavesdropping by rival males. Although there is currently no information about rivalry behaviour in A. makarovi, male-male vibrational interactions have been described in other leafhopper species (Heady et al 1986;Hunt and Morton 2001;Nuhardiyati and Bailey 2005). The leafhopper S. titanus has a well developed intrasexual competition and intruding males use alternative tactics such as disturbance vibrational signals to disrupt an ongoing duet and satellite behaviour to approach silently a duetting female (Mazzoni et al 2009a, b).…”

Duetting Behaviour in the Leafhopper Aphrodes makarovi (Hemiptera: Cicadellidae)

et al. 2011

Mate recognition and location in Cicadellidae is mediated exclusively via substrate-borne vibrational signals. In the present study we investigated vibrational signals and mate searching behaviour of the leafhopper Aphrodes makarovi. We studied mating behaviour and exchange of vibrational signals between live insects and in playback experiments. Males emitted long and complex calling signals composed of several sections. Female reply was long and always overlapped the end of the male call. The exchange of male and female vibrational signals was a complex and dynamic interaction during which both partners modified their signals according to partner's reply. The duration of female reply was influenced by the duration of the male call to which she was responding, while the duration of male call was influenced by the duration of the previous female reply. Such relationship suggests the role of sexual selection in the evolution of male vibrational signals.
