The aromatic beta-carboline norharmane was determined in workers, nymphs, and ergatoids of Reticulitermes speratus (Kolbe) (Isoptera: Rhinotermitidae) by gas chromatography/mass spectrometry. Norharmane levels in workers, nymphs, and ergatoids collected in May (approximately 4.3 ng/termite) were higher than those in November (approximately 0.2 ng/termite).(More)

The aromatic-carboline norharmane, which is located in the fat body of Reticulitermes speratus, stimulated the activity of juvenile hormone epoxide hydrolase (JHEH) of larva, ergatoid, and nymphoid homogenates. JHEH activity of ergatoid (16.67 ± 1.30 μU/termite) and nymphoid (20.94 ± 1.64 μU/termite) homogenates fortified with 0.1 mM norharmane was(More)
