Abstract:		"SCOT capillary Chromatographic and SCOT capillary chromatographic-mass spectrometic analyses of gland washes and effluvia of virgin femaleChoristoneura occidentalis Free, have been conducted with both a diapausing and nondiapausing strain of this insect. The following compounds were identified in gland washes and effluvia in both strains:E andZ11-14ratioAld,E andZ11-14ratioAc,E andZ11-14ratioOH and 14ratioAld, 14ratioAc, and 14ratioOH. The average aldehyde: acetate: alcohol ratio found by analysis of single glands by virgin females (nondiapausing strain) was 1ratio7ratio0.73. Analysis of virgin female effluvia gave this ratio as 10ratio3ratio8 (diapausing strain: %Z=8, 11, 15, respectively) and 10ratio3ratio6 (nondiapausing strain: %Z=8, 11, 12, respectively). The saturated components were generally 1-2% of theE isomer in each case. Comparisons of EAG responses of bothC. occidentalis andC. fumiferana toE11-14ratioAld,E11-14ratioAc andE11-14ratioOH were made. Correlations with both laboratory and field data previously published were also made betweenC. fumiferana andC. occidentalis"
