The behavioral data robustly suggested that the 3 alkanols synergistically created a female attractant odor or male pheromone in the budgerigar and that bird uropygial glands have broader implications in sexual behavior than previously known.

张健旭研究组在性信息素，即费洛蒙研究方面获得了多个成果，曾以以11页的篇幅，在国际上首次阐述了比小鼠更与人类接近的模式动物——大鼠的性信息素成分。

The mating disruptions of the sex pheromone on the concentration of 0.15 g/0.1 ha, 0.75 g/0.1 ha and 2 g/0.1 ha were very low, the attraction inhibition were 14, 20.5 and 14.3 %, respectively. The number of egg mass of L. xylina had not been decreased significantly after the mating disruptants treated.

性费洛蒙浓度於0.15 g /0.1 ha、0.75 g /0.1 ha及2 g /0.1 ha对黑角舞蛾的诱引抑制率很低，分别为14、20.5及 14.3 %，翌年卵块数目没有明显下降，显示没有达到交尾干扰效果，其原因在文中会加以讨论。

The female sex pheromone of the banded cucumber beetle,-6,12-dimethyl pentadecan-2-one, was obtained in 19.8% overall yield through 17 steps, using-4-methylvalerolactone as the starting material.

以-4-甲基戊内酯为原料，经过最长线性步骤17步，以19.8%的总收率合成了蔬菜害虫Diabrotica balteata LeConte的雌性信息素的主要成分(6R，12R)-6，12-二甲基-2-十五酮。

Delta-shaped traps baited with virgin females in the field attracted (233±16.3) males per day, whereas traps containing virgin males attracted 0 female and (1±0.6) male per day, indicating the presence of a female sex pheromone in R. longicauda.

活体雌蚊诱捕器田间诱捕雄蚊(233±16.3)头／24 h，活体雄蚊诱捕器诱捕雌蚊0头／24 h、雄蚊(1±0.6)头／24 h，说明雌蚊对雄蚊有引诱作用，而雄蚊对雌蚊、雄蚊均无引诱作用，菊花瘿蚊由雌蚊释放性信息素吸引雄蚊交配。
