Table 2. Mean catches (± SEM) and estimated catch indices of pooled males and females G. pallidipes in cow urine and acetone-baited Ngu traps combined with individual compounds.

Aldehydes (n = 12)					Ketones (n = 10)
Treatment	Mean catches*	% CR	Estimate	Catch index	Treatment	Mean catches*	% CR	Estimate	Catch index
Baited trap	28.17 ± 5.65 b	-	-	-	Baited trap	31.40 ± 7.72b	-	-	-

Experiments were carried out in 6 x 6 and 5 x 5 Latin square designs for the aldehydes and ketones, respectively. Means with the same letter, within the same column, are not significantly different. n, total number of replicates for each treatment; CR, catch reduction. 1, heptanal; 2, 6-methyl-5-hepten-2-one; 3, octanal; 4, acetophenone; 5, nonanal; 6, decanal; and 7, geranylacetone. Baited trap, positive control; WRC, negative control.
