     signals of different modalities are involved in the behaviour of the green stink bug, nezara viridula (l.) (pentatomidae, heteroptera). long range attraction is mediated by male pheromones, resulting in aggregation of bugs on the same plant where vibratory signals, vision and various chemical signals become important. both males and females sing spontaneously. when both are on the plant, males start vibratory communication as often as females. females induce the exchange of vibratory signals spontaneously or triggered by the male pheromone while males initiate the duet either spontaneously or after seeing the female. males and females sing spontaneously and respond to signals of different modalities more often in the daylight than in the dark. long lasting autonomous emission of the female calling song is present when triggered by the male pheromone and males respond to female calling predominantly by the emission of the courtship song.
