Abstract: | "Two sex pheromone components, 3(Z),6(Z),9(Z)-nonadecatriene (3Z,6Z,9Z-19 ratio H), and 3(Z),6(Z),9(Z)-eicosatriene (3Z,6Z,9Z-20ratio H), have been positively identified, and a third component, 6(Z),9(Z)-nonadecadiene (6(Z),9(Z)-19 ratio H) has been tentatively identified from abdominal tip extracts of female spring cankerworm moths,Paleacrita vernata Peck (Lepidopteraratio Geometridae). The pheromone components were identified by a combination of gas chromatography, electroantennography, mass spectrometry, chemical tests, comparison with standards, and field testing. Only 3Z,6Z,9Z-20 ratio H exhibited significant attractant activity when tested alone, and it was potentiated by the other two components. The attractive blend was an 8ratio2ratio1 ratio of 3Z,6Z,9Z-20ratioH/3Z,6Z,9Z-19ratioH/6Z,9Z-19ratioH. However, the two-component blend of 3Z,6Z,9Z-20 ratio H and 6Z,9Z-19 ratio H (8ratio1 ratio) was as attractive as the three-component blend in further field tests. A series of related compounds, the diene monoepoxides available from epoxidation of C19 and C20 3Z,6Z,9Z-trienes, some of which have been found in the pheromone blends of other moth species, were tested as behavioral antagonists. The attraction of male moths to synthetic lures was suppressed by the addition of 6Z,9Z-cis-3,4-epoxy-nonadecadiene to the lures. Additional experiments were performed to determine the effects of lure dosage, trap height, and trap design on the numbers of male moths captured" |
