| Abstract: | This paper reviewed the status of complex and interspecies diversity of Bark Beetles chemical communication, discussed the behavior regulation mechanism of kairomones, allomones and pheromones in the host selection, attack, colonization and reproduction of Bark Beetles. And it stated that the semiochemicals biogenesis and release of Bark Beetles effect on the population density, spatial niche and attacking time, and effect on the entomophagous insect species, population density and their control role to Bark Beetles. |
