### Behavioural Responses of T. hawaiiensis to the Main Components of G. jasminoides VOCs  
#### 3.3.1 Six-Arm Olfactometer Bioassays  
In these experiments, the number of insects that entered the control arm connected to the vessel with mineral oil were significantly lower than those of insects found in the arms with the different doses of linalool ([PERSON] test: \(\chi^{2}\) = 30.00, \(df\) = 5, \(p\) < 0.001, [PERSON] tests: \(p\) = 0.026-0.028), (Z)-3-hexenyl tglate ([PERSON] test: \(\chi^{2}\) = 29.88, \(df\) = 5, \(p\) < 0.001, [PERSON] tests: \(p\) = 0.026-0.027), or (E3,E7)-4,8,12-trimethyltrideca-1,3,7,11-tetraene ([PERSON] test: \(\chi^{2}\) = 29.88, \(df\) = 5, \(p\) < 0.001, [PERSON] tests: \(p\) = 0.026-0.028) (Figure 2). \begin{table}

Table 1: Volatile components of _G. jasminoides_ flower. There were relatively significant differences in attraction among all doses of linalool (Wilcoxon tests: \(p=0.026\)-0.028), (Z)-3-hexenyl tiglate (Wilcoxon tests: \(p=0.026\)-0.038), and (E3,E7)-4,8,12-trimethyltrideca-1,3,7,11-tetraene in a six-arm olfactometer. Control was mineral oil. Each box plot represents the median and its range of dispersion (lower and upper quartiles and outliers). Above each box plot, different letters indicate significant differences (Wilcoxon test, \(p<0.05\)).

Control was mineral oil. Each box plot represents the median and its range of dispersion (lower and upper quartiles and outliers).
