TRADIZIONE E INNOVAZIONE NEL CONTROLLO DEL PHILAENUS SPUMARIUS LINNAEUS, 1758 (HEMIPTERA APHROPHORIDAE)

Philaenus spumarius L., 1758 has rarely been considered a pest until the evidence of its attitude to transmit the phytopathogenic bacterium Xylella fastidiosa (Wells, Raju et al. 1986) ssp. paucaOQDS strain, responsible for the Olive Quick Decline Syndrome. This attitude requires the rational control of this new key±pest of olive by choosing means, control actions by efficacy, application timing, measuring mortality factors efficacy, impact and side effects. Exploiting for rational in Philaenus spumarius control, we are also targeting population size assessment by AquaSamPling (ASP) that purposely inspired MXYHQLOHV¶ lifestyle washes herbs and filter floating insects. Integration among control means is currently studied by effectiveness measure and quantification as mortality of juvenile due to weeds shredding, hot steam distribution or chemical control also based on carboxylic acids (C14-C20) potassium salts, pelargonic acid, sweet orange essential oil or others. Insecticides based on several synthetic active substances, with different MoA (IRAC: 1B, 3A, 4A, 4C, 9B, 16 and 23) and MoE (contact and ingestion, contact or ingestion), were distributed by spraying or injection. Formulates are conventional, adjuvant joined, or prepare for tree injection. Olive trunks were injected by innovative device as BITE (Blade for Infusion in TrEes) that injects formulates sustainably. Concerning IPM biological control components we focus on Zelus renardii Kolenati, 1856 (Hemiptera Reduviidae) mass rearing, the assassin bug has a good P. spumarius adult preying attitude that makes it an interesting candidate in inundative biological control programs. Each mortality factor under consideration must be evaluated within control strategies, measuring its effectiveness against the target species and the impact in the broadest sense of the term.
