摘要:

A mixture of (E)-2-hexenal, α-terpineol, linalool, terpinen-4-ol, and benzyl alcohol attracts adults of the predaceous spined soldier bug, Podisus maculiventris (Say). The male-produced pheromone contains (+)-α-terpineol; however, ()-α-terpineol is not inhibitory to the bug, so artificial pheromone can be made with racemic α-terpineol. Four parasitic species use the pheromone as a kairomone and two of these parasitoids are partially inhibited by ()-α-terpineol. This is the first artificial long-range pheromone for a member of the true bugs (Hemiptera: Heteroptera) and the first such pheromone for a nonsocial predaceous insect.
