Liedtke, H. C., Åbjörnsson, K., Harraca, V., Knudsen, J. T., Wallin, E. A., Hedenström, E. & Ryne, C. 2011. Alarm pheromones and chemical communication in nymphs of the tropical bed bug Cimex hemipterus (Hemiptera: Cimicidae). PLos ONE 6(3) e18156.
The study showed that the antennal morphology and volatile emissions (alarm pheromones) of the tropical bedbug closely resemble those of the common bed bug (Cimex lectularius), though in somewhat different ratios. The nymph specific compounds are suggested to be the cause of a repellent effect demonstrated in biotests.
The findings suggest that common pheromone-based pest control methods can be used for both the common and the tropical bed bug.
