Termite responses to glass dummies treated with heneicosane or tetracosane alone and together with worker extracts. Lateral shaking (A) and antennation (B) in response to glass dummies treated with heneicosane (n-C21) or tetracosane (n-C24) alone (blue bars) and with worker extracts (red bars) were measured during 5-min assays for each treatment. Glass dummies were coated with 20 μL of each solution. Worker extracts were created by pooling six workers with mass approximately equal to three neotenic queens to approximate the queen concentration. Each assay dish consisted of 30 workers, 2 soldiers, and an introduced glass dummy. Letters indicate significance using one-way ANOVA and Tukey’s HSD. Error bars are SEM. Ten replicate assays were conducted for each treatment.
