S1 Table. Amount (in grams) of each compound in 4.5 g of each blend reflecting their natural ratios of occurrence in zebra skin odor.
S2 Table. Mean catches ± SEM in the initial trials to determine the optimum repellent doses for each compound and blend in three replicates trials.
Blend A, K, and Z indicate 4-component blend of aldehydes, 3-component blend of ketones and 7-component blend of all EAD-active compounds, respectively, in their natural ratios of occurrence in zebra skin odor. Values underlined represent catches at optimum repellent dose (i.e. dose with the least catch or not significantly different from the dose that did).
S3 Table. Release rates ± SEM of individual compounds and blends from polyethylene sachets in three replicates.
Blend A, K, Z and 2C Blend K indicate 4-component blend of aldehydes, 3-component blend of ketones, 7-component blend of all EAD-active compounds and 2-component blend of ketones respectively, in their natural ratios of occurrence in zebra skin odor.
S1 Fig. GC/EAD profiles showing antennal responses of G. pallidipes to commercial standards of the physiologically-active compounds in zebra skin odor extract.
A aldehydes and B ketones. Upper trace is the GC/FID and lower traces represent EAD responses. 1, heptanal; 2, 6-methyl-5-hepten-2-one; 3, octanal; 4, acetophenone; 5, nonanal; 6, decanal; and 7, geranylacetone. The EAD runs were scaled to 10mV/div.
