Y-shape trail-following bioassays using activated workers for active thresholds and synergistic effect.

Samples were (3Z)-dodec-3-en-1-ol (DOE), (3Z,6Z)-dodeca-3,6-dien-1-ol (DDE), a blend of both compounds, a sternal gland extract (GEQ), an abdominal tergites extract (WEQ) in O. formosanus workers or soldiers. Hexane was used as control in the other branch. Selections were analyzed with a Mann-Whitney U-test with Continuity Correction (***P<0.001; **P<0.01; ns, not significant, P > 0.05). The columns marked with the same small letter were not significantly different (Diff) (P > 0.05); n indicated the total number of termites used.
