(Z)-3-dodecen-1-ol (E)-2-butenoate and its use in monitoring and controlling the sweetpotato weevil

摘要

A pheromonal compound produced by the sweetpotato weevil has been identified as (Z)-3-dodecen-1-ol (E)-2-butenoate. The synthetically-prepared compound demonstrates activity toward the sweetpotato weevil comparable to or greater than that of the natural female and comparable to that of its natural counterpart under field conditions. The novel compound provides a sensitive tool for detection of the sweetpotato weevil. By attracting adult weevils to field traps, this compound provides a means for monitoring and controlling this major agricultural pest.
