Figure 8From: Identification of a self-regulatory pheromone system that controls nymph aggregation behavior of rice spittlebug Callitettix versicolor Behavioral responses of fifth instar nymphs of C. versicolor to various doses of mixtures of (a) undecane + pentadecane, (b) dodecane + pentadecane, (c) tridecane + pentadecane, (d) tetradecane + pentadecane, (e) hexadecane + pentadecane and (f) all these six compounds. Each assay block consisted of testing 10 to 20 nymphs individually and mean ± SE were calculated from 3 blocks of assays. There were significant differences between the responses of nymphs with different characters (p < 0.05, one-way ANOVA with LSD test).Back to article page
