Abstract
Using an electron capture detector, a sensitive gas chromatographic method has been developed for the determination of the juvenile hormone methyl(2E, 6E)-10, 11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate (JH III) in insect material. The sensitivity in electron capture detection of the bisheptafluorobutyrate was determined. The work-up procedure was checked by adding known amounts of JH III to insect material. The method seems equally applicable to all three juvenile hormones.
