Wine-baited traps to evaluate the efficacy of the mating disruption technique against Lobesia botrana in Douro Demarcated Region

Description

Abstract: Wine-baited traps as tools for assessing effectiveness of the mating disruption technique (MD) against Lobesia botrana were used in vineyards of the Douro Demarcated Region. More specifically, this type of “food trap” was tested to: i) monitor the second and third flights of L. botrana in plots under MD; (ii) investigate the influence of uncultivated habitats and/or neighbouring MD-free vineyards on the pest occurrence in MD-treated plots; (iii) detect the mating status of the females captured. As expected, this type of trap was capable of capturing both males and females of L. botrana and other moths, despite the presence of specific clouds of synthetic pheromones, proving to be a valid basic and complementary tool to better understand and improve the MD against European grapevine moth.
