Abstract

Matsucoccus resinosae in the United States,M. matsumurae in China, andM. thunbergianae in Korea use (2E, 4E)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one (1) (matsuone) as the primary component of their sex attractant pheromones. The structure was postulated from mass and NMR spectra and confirmed by synthesis of analogs3, (2E,4E)-4,6,11,12-tetramethyl-2,4-tridecadien-7-one, and4, (2E,4Z)-4,6,11,12-tetramethyl-2,4-tridecadien-7-one. Both analogs were attractive to the males ofM. resinosae in laboratory bioassays and toM. matsumurae in laboratory and field tests, but the 4Z analog (4) was much less so than the 4E analog (3) and had inhibitory effects at high concentrations. Dodecanol, isolated from aeration and solvent extracts of femaleM. resinosae, evoked characteristic wing-raising by pedestrian males, but the role of this response was not determined.
