AB 1. Cerambyx welensii Küster (Coleoptera: Cerambycidae) is a wood-borer responsiblefor the decline of Mediterranean oaks in open woodlands.2. To establish that contact pheromones are involved in mate recognition ofC. welensii, we extracted the cuticular hydrocarbons by solid phase microextractionat pre-reproductive, beginning and ending of the reproductive period, and by solventextraction of prothorax and elytra. The extracts were analysed by GC–MSunder electron impact and chemical ionization conditions. Cuticular hydrocarbonprofiles varied according to the reproductive period, although differences betweensexes were not significant. Two compounds, 11/13-methylheptacosane and11-methylnonacosane were more abundant in females at the beginning and endingof the reproductive periods. Compound 11/13-methylheptacosane was also morerepresentative in female prothorax than in males, and 2-methyloctacosane wasricher in male elytra than in females.3. We also studied the role of cuticular hydrocarbons in mate recognition in arena bioassays.Treatment of solvent-washed dead females and glass dummies with onefemale equivalent (FE) of cuticular extract elicited mating responses in males, especiallyat the beginning of the reproductive period, with copulation attempts reaching61.9% on solvent-washed dead females and 23.8% on dummies. The successivetreatment with synthetic compounds approaching a male cuticular profile inhibitedmale response.4. Our results confirm that contact pheromones mediate mate recognition inC. welensii. Knowledge of the precise role played by the major compounds11/13-methylheptacosane and 11-methylnonacosane and other minor compoundsrepresentative in female prothorax may contribute to the development of novelmanagement strategies against C. welensii.
