Many species of small-bodied pests experience classical responses to host resistance phenomena during an encounter with foliage of 5. berthaultii. These include host avoidance and restlessness, reduced feeding, delayed development, reduced adult weight and reproductive performance, increased mortality, and diminished longevity. In several cases, these responses are associated with entrapment or immobilization by trichome exudate. 

Where several species of bark beetle co-exist and also use the same host tree species for breeding, one species may exploit the pheromone of another and so colonize a host more efficiently, or conversely, it may avoid the pheromone of another species and so avoid potential hybridization or detrimental competition for a resource. Wood (1970) suggested that the specificity of pheromones in the Scolytidae might be one mechanism maintaining breeding isolation between sympatric species. This has been substantiated for sympatric species of Ips, and besides breeding isolation, competition for host resources is also mediated via chemical communication. Two mechanisms have been discovered (i) nonattraction to the pheromone of another species, and (ii) interruption of a potential response to host material occupied by another species.
