Monitoring and controlling olive flies

Sex pheromone of the olive fly, Daws oleae, is used as an attractant in methods for the monitoring and control of the fly. The pheromone has the chemical mane 1,7-dioxaspiro (5,5)undecane (abbreviated to DSU). Prepn. of DSU comprises self-condensing delta-vabrolactone (II) under basic conditions, fo...

Zusammenfassung:	Sex pheromone of the olive fly, Daws oleae, is used as an attractant in methods for the monitoring and control of the fly. The pheromone has the chemical mane 1,7-dioxaspiro (5,5)undecane (abbreviated to DSU). Prepn. of DSU comprises self-condensing delta-vabrolactone (II) under basic conditions, followed by acidification. The prod. is a racemic mixt. of (Ia) and (Ig). A trap for male D.oleac, e.g. a window trap comprises an effective amt. of DSU and conventional means for retaining the fly in the trap e.g. adhesive surfaces or a tortuous path to the exit, or for killing e.g. one or more insecticides or an electrically charged grid. Generally about 1-100 mg of DSU are used per trap. The trap may also contain the sex pheromone of Prays oleae, the olive moth, viz. Z-7-tetradecenal.
