Abstract

This article focuses on identifying the aggregation-sex pheromone of the cerambycid beetle species *Eustromula valida* (LeConte) in southern California. Field trials using generic blends of known cerambycid pheromones initially attracted *E. valida* weakly, but chemical analysis of volatiles from live males revealed that males produce 3-methylthiopropan-1-ol (methionol), a sulfur-containing compound not included in the tested blends. Subsequent bioassays demonstrated that methionol alone strongly and specifically attracts both sexes of *E. valida*, confirming it as the species’ male-produced pheromone. The study also notes that methionol has been identified as a pheromone component in other cerambycid species across North and South America, suggesting it may be a common pheromone within the subfamily Cerambycinae.
