Isolation, identification and stimulatory activity of a second component of the sex pheremone system (complex) of the female almond moth, Cadra cautella (Walker)

$\text{Cis}$-9-tetradecen-l-ol acetate was isolated from both extracts of female abdominal tips and of filter paper exposed to female $\text{Cadra}$$\text{cautella}$ (Walker). It is the second sex stimulant isolated from this species and, in stimulatory bioassays, it is ca. 1/100, 000 as active as the stimulant isolated previously, $\text{cis}$-9, $\text{trans}$-12-tetradecadien-l-ol acetate. According to attractancy tests, the natural sex pheromone system of complex contains other components in addition to these 2 stimulants.
