Sex pheromone of the tea tortrix moth (Homona coffearia Neitner)
- 68 Downloads
Three compounds were isolated from female abdominal tips of the tea tortrix,Homona coffearia Neitner (Lepidoptera: Tortricidae) and identified as 1-dodecanol, 1-dodecyl acetate, and (E)-9-dodecen-1-yl acetate by chemical tests and mass spectrometry. These were the only appreciably active compounds detected in female gland extracts by male electroantennography of gas chromatographic collections. Synthetic (E)-9-dodecenyl acetate was shown to be active in attracting male moths in the field, and this activity was greatly increased by addition of dodecyl acetate and dodecanol. A very active lure for monitoring consists of 1 mg (E)-9-dodecenyl acetate, 3 mg dodecanol, and 1 mg dodecyl acetate in a polyethylene cap.
