ABSTRACT
Stink bugs, similar to many other insects, use multimodal communication, comprising chemical, visual, and vibrational signals. Chemical communication is probably the most important signal used by insects at long distances and at medium to short distancesto locate hosts and find mates and food. Chemical communication in stink bugs has been widely studied, and there are some good reviews on this topic (Millar 2005, McBrien and Millar 1999, and more recently, Weber et al. 2016, in press). The stink bugs’ semiochemistry comprises different signals, like sex, aggregation, and alarm pheromones, allomones, kairomones, and synomones. These signals are produced by different structures in the insects, like dimorphic cells, cuticular glands, and metathoracic glands (MTGs) in adults and dorsal abdominal glands (DAGs) in nymphs (Aldrich et al. 1978, Aldrich 1988, Borges and Aldrich 1992, Aldrich et al. 1994, Borges and Aldrich 1994).
