Open-field Y-shape trail-following bioassays with O. formosanus activated D phase workers showing preference to recruitment pheromone.

The sample arrangements were 0.01 gnawing worker sternal gland extract (0.01 GWG/cm) laid in base and one arm, (3Z)-dodec-3-en-1-ol (DOE), (3Z,6Z)-dodeca-3,6-dien-1-ol (DDE), soldier sternal gland extract (SDG), and searching worker sternal gland extract (SWG) laid down in the other arm for contrast. The same protocol was used as in footnote of Table 3.

样本布置方案如下：在实验装置的基底与单侧臂上铺设0.01 啮食工蚁腹板腺提取物（gnawing worker sternal gland extract, GWG，浓度为0.01 GWG/cm）；在另一侧臂上铺设(3Z)-3-十二碳烯-1-醇（(3Z)-dodec-3-en-1-ol, DOE）、(3Z,6Z)-3,6-十二碳二烯-1-醇（(3Z,6Z)-dodeca-3,6-dien-1-ol, DDE）、兵蚁腹板腺提取物（soldier sternal gland extract, SDG）以及觅食工蚁腹板腺提取物（searching worker sternal gland extract, SWG）作为对照。本实验采用与表3脚注一致的实验方案。
