Reproductive strategy of the leafhopper Orientus ishidae Matsumura (Hemiptera: Cicadellidae)López Díez, Juan José (Avtor) Rusjan, Denis (Mentor) Virant Doberlet, Meta (Komentor) mating behaviourOrientus ishidaeleafhopperphytoplasmaFlavescence doréemating disruptionvibrational communicationOrientus 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.[J. J.
