Sex Pheromone of the Smaller Clearwing Moth Synanthedon tenuis (Butler)

Abstract

The smaller clearwing moth, Synanthedon tenuis (Butler) (Lepidoptera: Sesiidae), is a major pest of persimmon in northeast Asia. A previous study reported attraction of S. tenuis males to Z3,Z13-18:OAc, but this compound had no effect on male catch in the persimmon orchards in Korea. In this study, we analyzed pheromone gland extracts of S. tenuis females and identified Z3,Z13-18:OH as the main component. In field trapping trial, Z3,Z13-18:OH alone was attractive to S. tenuis males and competitive with live virgin females. These results indicate that the pheromone of this species consists of a single component, Z3,Z13-18:OH. However, Z3,Z13-18:OAc, a previously reported attractant, was not detected in the gland extracts of females. Furthermore, the addition of Z3,Z13-18:OAc to the main pheromone component strongly inhibited attraction for males, suggesting that the diene acetate is not a pheromone component. This is the first report of an octadecadienol as female-produced sex pheromone from the genus Synanthedon.

Stored product pest Nemapogon variatella (Clemens): Identification of sex pheromone, putative antagonist and mitotype characterization

“…Recent studies on the sex pheromone of N. granella have shown that it can be effectively used to control pests through mating disruption in ham factories (Savoldelli et al, 2023).

“…Z 3 Z 13‐18:OH has been identified as a sex attractant component for three other moth species of Tineidae ( Triaxomera fulvimitrella Sodoffsky, Nemapogon flavifrons Petersen, Monopis monachella Hübner; Būda et al, 1993; Karalius et al, 2005). Nevertheless, as a pheromone or one of the components of pheromones Z 3 Z 13‐18:OH is more common in sesiids ( Aegeria tibialis Harris, Carmenta chrysophanes Meyrick, Glossosphecia romanovi Leech, Nokona pernix Leech, Paranthrene robiniae Edwards, P. tabaniformis Rottemburg, Sesia apiformis Clerck, Sphecia siningensis Hsu, Synanthedon haitangvora Yang, S. bicingulata Staudinger, S. tenuis Butler; Cowles et al, 1996; Francke et al, 2004; Guangzhong et al, 1990; Kovalev et al, 1988; Mozūraitis & Karalius, 2007; Naka et al, 2006, 2010; Underhill et al, 1978; Vickers & Rumbo, 2001; Yang et al, 2009, 2012; Yang, Cho, & Choi, 2011; Yang, Kim, & Lee, 2011).…”
