In a field bioassay conducted in Brazil, significant numbers of males and females were caught in traps baited with synthesized Editor: Cesar Rodriguez-Saona, Rutgers The State University of New Jersey, UNITED STATES racemic 10-methyldodecanal, consistent with the aggregation-sex pheromones produced by males of many cerambycine species. This compound represents a new structural class Received: June 16, 2016 of cerambycid pheromones, and it is the first pheromone identified for a species in the tribe Accepted: July 25, 2016 Eburiini.
