研究了小地老虎(Agrotis Ipsilon)性信息素信号和反应的周期性和年龄相关性。雌蛾在羽化后的第一晚开始鸣叫，主要在暗期的后半段鸣叫。雌性叫声的比例从1日龄增加到3日龄，从3日龄下降到6日龄(P<；0.001)。1日龄雌鱼呼唤的时间晚于2日龄和3日龄雌鱼(P=0.016)。1~2日龄雌虫信息素腺体提取液中Z7-12：Ac、Z9-14：Ac和Z11-16：Ac的含量随光周期的变化而变化，在暗期增加，在光期减少(P<0.001)。这些振荡用包含周期为24小时的角项的方程来描述。Z7-12：Ac和Z9-14：Ac的数量随雌性年龄的增加而变化，而Z11-16：Ac的数量则不随年龄变化(P<；0.001，P=0.021和P=0.529)。Z9-14：Ac和Z11-16：Ac与Z7-12：Ac的比值在整个叫期不随年龄和时间变化。雄性在风洞中对雌性信息素的反应随着年龄和暗期时间的增加而增加。雄性的反应类型(飞行、定向飞行和信息素来源接触)受年龄和暗期时间的影响(P<；0.001)。
Periodical and age-related changes in sex pheromone signaling and response were studied in the black cutworm moth, Agrotis ipsilon. Females began to call on the first night after eclosion and called mainly during the second half of the scotophase. The percentage of females calling increased from 1- to 3-day-old Females and decreased from 3- to 6-day-old females (P < 0.001). One-day-old females called later in the scotophase than 2- and 3-day-old females (P = 0.016). The quantity of Z7-12:Ac, Z9-14:Ac, and Z11-16:Ac in pheromone gland extracts of 1- to B-day-old females varied with rime of the photoregime, increasing during scotophase and decreasing during photophase (P less than or equal to 0.001). These oscillations were described by using equations containing angular terms with a period of 24 hr. The quantities of Z7-12:Ac and Z9-14:Ac, but not of Z11-16:Ac, varied with female age during the calling period (P < 0.001, P = 0.021, and P = 0.529, respectively). The ratios of Z9-14:Ac and Z11-16:Ac to Z7-12:Ac did not change with age or time during calling period. Male response to female pheromone in a wind tunnel increased with age and time of the scotophase. The type of response exhibited by the males (taking flight, oriented flight, and pheromone source contact) was affected by both age and time of the scotophase (P < 0.001).
