Mating repulsion of male Cimex lectularius is regulated by the nymph-emitted alarm pheromone. (a) Frequency of male mounting on females and nymphs (n = 15 for each treatment) is the same (Kruskal-Wallis test: χ2 = 1.749, P = 0.626). (b) The percentage of mating with females (n = 14), nymphs (n = 12), silenced nymphs (with covered dorsal abdominal glands (n = 13) and sham-treated nymphs (n = 14), on the other hand, differs. Different letters represent significant differences in percentage of mating among the different associations.
