Table 3. Mean trap catches (SEM) and catch indices of G. pallidipes in cow urine and acetone-baited Ngu traps combined with different blends (n = 10).
| Female | Male | |||||||
|---|---|---|---|---|---|---|---|---|
| Treatment | Trap catches* | % CR | Estimate | Catch index (95%) | Trap catches* | % CR | Estimate | Catch index (95%) |
| Baited trap | 20.1 ± 5.28c | - | - | - | 11 ± 3.76c | - | - | - |
| Baited trap + WRC | 7.9b ± 1.75a | 60.7 | -1.02 | 0.36 (0.23–0.56) | 4.8 ± 1.76a | 56.4 | -1.01 | 0.37 (0.22–0.6) |
| Baited trap + Blend A | 17.1 ± 5.24bc | 14.9 | -0.34 | 0.71 (0.47–1.06) | 11.2 ± 3.49bc | -1.8 | -0.14 | 0.87 (0.56–1.34) |

Experiment was carried out following a 5 x 5 Latin square design. Means with the same letter, within the same column, are not significantly different. n, total number of replicates for each treatment; CR, catch reduction. Blend A, K, and Z indicates 4-component blend of aldehydes, 3-component blend of ketones and 7-component blend of all EAD-active compounds, respectively, in natural ratios of occurrence in zebra skin odor. Baited trap, positive control; WRC, negative control.
