Gas chromatographic and mass spectral analyses were conducted on the pheromone gland extracts of female moth of Helicoverpa armigera (Lepidoptera:Noctuidae). Saturated aldehyde (16:Ald), (Z)‐9‐hexadecenal (Z‐9–16:Ald), (Z)‐11‐hexadecenal (Z‐11–16:Ald), hexade‐canol (16:OH) and (Z)‐11‐hexadecenol (2–11–16:OH) were found from gland extracts in the ratio of 6.1:4. 5 :100:3. 5 :8.8. In field tests of Shandong and Shanxi Provinces, 2 mg blends of Z ‐11–16:Ald and Z‐9–16:Ald (97:3) applied on a rubber dispenser effectively attracted H. armigera males. The addition of 4%‐7% 16 :Ald to the binary mixture caused increase over that of the binary mixture. The addition of 1% Z‐ 11–16:OH to binary or trinary mixture may reduce catches, while addition of 5% Z‐11–16:OH reduced catches singnificantly.
