From: β-caryophyllene emitted from a transgenic Arabidopsis or chemical dispenser repels Diaphorina citri, vector of Candidatus Liberibacters

Figure 2

Responses of D. citri, tested in a 4-arm-olfactometer, to different concentrations of two synthetic volatiles, dimethyl disulphide (DMDS) and β-caryophyllene (β-car) dissolved in hexane. Bars represent the overall percentage of time spent in each odor source, comparing air (grey bar) or a synthetic volatile (black bar) versus hexane (white bar). Error bars represent SE (n = 10 independent tests). The number of responding psyllids is indicated in the black bars and the total number of insects tested is given between parentheses for each comparison. Time spent in odor sources were analysed by paired t-test. Asterisks indicate significant differences between odor sources (*P < 0.05).
