Dendroctonus
Dendroctonus is a genus of bark beetles. Its name in New Latin is derived from Ancient Greek δένδρον dendron "tree", and κτόνος ktonos "murder", alluding to its ability to kill trees. It includes several species notorious for destroying trees in the forests of North America. The genus has a symbiotic relationship with many different yeasts, particularly those in the genera Candida and Pichia that aid in digestion and pheromone production.
Various bacterial species also appear to be associated with larvae or adults of different species of Dendroctonus. For example, the bacterial species Rahnella aquatilis, Stenotrophomonas maltophilia, Raoultella terrigena,Ponticoccus gilvus, and Kocuria marina help the species Dendroctonus rhizophagus by cellulose degradation. Dendroctonus rhizophagus is endemic to the Sierra Madre Occidental in Mexico and is an economically important insect pest there, it can severely damage or kill seedlings and young trees of eleven pine species.
