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 andZ11-14∶Ald,E andZ11-14∶Ac,E andZ11-14∶OH and 14∶Ald, 14∶Ac, and 14∶OH. The average aldehyde: acetate: alcohol ratio found by analysis of single glands by virgin females (nondiapausing strain) was 1∶7∶0.73. Analysis of virgin female effluvia gave this ratio as 10∶3∶8 (diapausing strain: %Z=8, 11, 15, respectively) and 10∶3∶6 (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 toE11-14∶Ald,E11-14∶Ac andE11-14∶OH were made. Correlations with both laboratory and field data previously published were also made betweenC. fumiferana andC. occidentalis.

摘要

已对滞育和非滞育两种品系的处女雌性Choristoneura occidentalis Free 的腺体分泌物和分泌物进行了 SCOT 毛细色谱和 SCOT 毛细色谱-质谱分析。在两种品系的腺体分泌物和分泌物中均鉴定出以下化合物：E 和 Z11-14∶Ald、E 和 Z11-14∶Ac、E 和 Z11-14∶OH 和 14∶Ald、14∶Ac 和 14∶OH。通过对处女雌性（非滞育品系）单个腺体的分析，发现平均醛：酯：醇比为 1∶7∶0.73。对处女雌性分泌物的分析得出的比率为 10∶3∶8（滞育品系：%Z=8、11、15，分别）和 10∶3∶6（非滞育品系：%Z=8、11、12，分别）。在每种情况下，饱和成分通常占 E 异构体的 1-2%。对 C.occidentalis 和 C.fumiferana 的 EAG 反应对 E11-14∶Ald、E11-14∶Ac 和 E11-14∶OH 进行了比较。还对 C.fumiferana 和 C.occidentalis 之间先前发表的实验室和现场数据进行了相关性分析。
