| Abstract: | Aliphatic and aromatic trifluoromethyl ketones have been evaluatedin the laboratory and in the field as inhibitors of the pheromoneresponse of the processionary moth Thaumetopoea pityocampa males.Among them, two compounds, (Z)-l, l, l-trifluoro-15-octadecen-13-yn-2-oneand (Z)-l, l, l-trifluoro-16-nonadeceo-14-yn-2-one, are closelyrelated analogs of the natural pheromone (Z)-13-hexadecen-11-ynylacetate. In the laboratory experiments, carried out by pre-exposureof males to vapors of the chemicals, |
