| Abstract: | "Males of several species in the large cerambycid beetle subfamily Lamiine, native to South and North America, are known to produce aggregation-sex pheromones composed of three related structures: the sesquiterpene catabolic product geranylacetone, its corresponding alcohol (known as fuscumol), and the acetate ester of the alcohol (fuscumol acetate). Here, we show that males of two lamiine species native to the eastern USA, Astylopsis macula (Say) and Leptostylus transversus (Gyllenhal) (both tribe Acanthocinini), produce pheromones composed of the structurally related (S)-6-methylhept-5-en-2-ol ([S]-sulcatol). Males of both species also produced 6-methylhept-5-en-2-one (sulcatone), and males of A. macula produced trace amounts of (R)-fuscumol acetate. Field experiments demonstrated that both species were attracted by (S)-sulcatol. Sulcatone was not attractive as a single component, nor did it influence attraction of A. macula to (S)-sulcatol, while its effect on L. transversus was unclear. Data from the field experiments, and a separate experiment using traps fitted with a timer mechanism that rotated trap jars, revealed that the two species overlap only slightly in both seasonal and daily flight period, thus minimizing interspecific attraction. Racemic fuscumol acetate and fuscumol antagonized attraction of both species to sulcatol. The identification of sulcatol as a cerambycid pheromone extends the known range of pheromone components in the subfamily Lamiinae" |
