Volatile terpenes were assayed in sixteen Gossypium hirsutum L. genotypes, seven of which were also analysed for terpenoid aldehydes. Consistent with previous studies, the major volatile terpenes detected were trans-b-caryophyllene, b-bisabolol, a-humulene, myrcene, g-bisabolene, trans-b-ocimene, a-pinene and b-pinene. Across genotypes, relative percentages of major individual terpenes were similar within, but differed widely between the leaf, square and boll coat. The boll coat was relatively rich in trans-b-ocimene and heliocides H1 and H4. These heliocides together accounted for approximately 50-80% of total terpenoid aldehydes in the boll coat. This finding may have significance for the development of cultivars resistant to Helicoverpa  spp. in Australia.
