ABSTRACT- We report evidence that the longhorn beetle, Neoclytus acuminatus, have both a contact pheromone and a long-range pheromone. Female beetles have cuticular hydrocarbons that males respond to by mounting the female when the male antennae come in contact with the female. We have identified two active hydrocarbons as 7Me-C27 and 9Me-C27. Field experiments show that male beetles produce a long-range attractant that the female beetle recognizes and follows to the male.
Key words: pheromone
