Fungus gnats show a preference for non-infected (Control) as compared to Virus-infected plants. We counted the number of fungus gnats that preferred non-infected and virus-infected plants and expressed this as a percentage of the total number of trials per plant pair (for statistical procedure see “Materials and Methods”). Bars give mean percentage of adult female fungus gnats which preferred non-infected or virus-infected plants, respectively, as determined in dual choice tests. Error bars standard errors, *p < 0.05
