Corrigendum: Evidence of a female-produced sex pheromone in the european pear psylla, cacopsylla pyri (Bulletin of Insectology 71, 1, 57-64, 2018)

Change “11,13-dimethylheptacosane” to “11,15-dimethylheptacosane” along all the text. Page 61, add figure 4, the experimental mass spectrum relevant to the peak 2 and the fragmentation scheme for the compound 11,15-dimethylheptacosane, similar to the one reported by Kenig et al. (1995). (Figure presented)Page 61, table 1, add this information in the footnotes “Molecular ions in the brackets were not visible in the spectrum, but could be inferred by the diagnostic ions”. Page 62, delete “11,13-dimethylheptacosane was reported as a sex pheromone component of Cataglyphis species (Hymenoptera Formicidae) (Dahbi et al., 1996).” Page 63, References, delete “DAHBI A., LENOIR A., TINAUT A., TAGHIZADEH T., FRANCKE W., HEFETZ A., 1996.-Chemistry of the postpharyngeal gland secretion and its implication for the phylogeny of Iberian Cataglyphis species (Hymenoptera: Formicidae).-Chemoecology, 7: 163-171.” Page 63, References, add “KENIG F., SINNINGHE DAMSTÉ J.
