Abstract
Orientus ishidae (Matsumura) (Hemiptera, Cicadellidae) is an invasive leafhopper from eastern Asia. Since it has a capacity to transmit Flavescence Dorée phytoplasma, this insect is a potential pest in vineyards. We studied vibrational communication in O. ishidae in order to understand the reproductive behaviour of this species and obtain necessary information needed to design control measures that can be applied to an Integrated Pest Management strategy and ecological viticulture. Vibrational repertoar of O. ishidae was rich and complex. Mating behaviour sequence can be divided into three phases, (1) recognition duet, (2) courtship phase that includes early and late courtship and (3) wing phase. Each phase was characterized by different types of male and female vibrational signals and duet structure. Each phase consisted of several cycles in which signals and phrases were repeated in a stereotyped pattern and progressively changed throughout the phase. Males had to complete all stages in order to obtain copulation. Male competitive behaviour was expressed in emission of high-amplitude rivarly signals emitted in the female reply window witin the duet with another male, as well as in satellite behaviour.

Title:Paritvena strategija japonskega škržatka Orientus ishidae Matsumura (Hemiptera: Cicadellidae)
Abstract:
Japonski škržatek (Orientus ishidae Matsumura; Hemiptera, Cicadellidae) je invazivna vrsta škržatka, ki izvira iz Vzhodne Azije. Zaradi zmožnosti prenašanja sevov fitoplazem Flavescence Dorée je lahko v vinogradih potencialni škodljivec. Preučevali smo vibracijsko komunikacijo japonskega škržatka, kar bi omogočilo razumevanje paritvenega vedenja vrste in odprlo možnost razvoja metod za kontrolo škodljivca, ki bi jih lahko uporabili v strategiji integriranega in ekološkega varstva rastlin. Vibracijski repertoar japonskega škržatka je bogat in kompleksen. Zaporedje paritvenega vedenja lahko razdelimo v tri faze, (1) duet prepoznavanja, (2) faza dvorjenja, ki vključuje zgodnje in pozno dvorjenje, in (3) faza kril. Vsako od faz so zaznamovali različni tipi vibracijskih signalov samcev in samic ter sestava dueta. Faze je sestavljalo po več ciklov, znotraj katerih so se ponavljale fraze v stereotipnem zaporedju in se postopoma spreminjale proti koncu faze. Samci so morali zaključiti vse faze, da so prišli do parjenja. Tekmovalno vedenje samcev se je izrazilo v obliki oddajanja rivalnih signalov z visoko amplitudo, oddanih v delu dueta, kjer bi moral priti samičin odgovor na signale drugega samca, kot tudi v obliki satelitskega vedenja.
