Bedbugs (Latin Heteroptera) - a suborder of insects from the squad of Hemiptera, previously considered as an independent unit. About 40 thousand species from more than 50 families. In the Far East of Russia there are about 800 species (for the former USSR more than 2000 species were indicated).
Most bugs have odorous glands, the holes of which are located in adults on the underside of the chest between the first and second pair of legs. The secretions of these glands have a characteristic odor that is unpleasant to humans, suggest that it scares off the enemies, and possibly acts as a pheromone. The secret consists mainly of aldehydes, for example close to CH3- (CH2) 2-CH = CH-CHO, and is close to the pheromones in composition.
