Dendroctonus mexicanus
Mexican bark beetle
Dendroctonus mexicanus is a bark beetle native to Mexico and Central America, recognized as the most widely distributed and destructive bark beetle in Mexico. It colonizes more than 21 pine species and causes significant tree mortality in coniferous forests. The species' population dynamics are strongly influenced by climate variables, particularly temperature and precipitation, with outbreak risk increasing under warmer, drier conditions. It is considered a major forest pest affecting wood supply and ecosystem services.

pseudotsugae
Douglas-fir beetle, Douglas fir beetle
The Douglas-fir beetle (Dendroctonus pseudotsugae) is a bark beetle native to western North America and a major pest of Douglas-fir (Pseudotsuga menziesii). Adults are small (4.4–7 mm), light brown when young, darkening to brown or black with reddish wing covers. Outbreaks typically follow disturbances such as storms, fire, or drought, which provide stressed or dead host trees. The species has one of the most thoroughly studied pheromone systems among bark beetles, with operational use of its antiaggregation pheromone (MCH) to protect high-value trees developed over 40 years of research. The beetle also infests downed western larch (Larix occidentalis), though brood do not survive in live larch due to high 3-carene content.
