Researchers discover key gene involved in bark beetle pheromone production

...National Academy of Sciences (PNAS). Bark beetles plague pine forests, especially when the trees are stressed. The Lake Tahoe basin lost 30 percent of its pines to bark beetle infestation during the 1986-1994 drought, according to Blomquist. There are several hundred species of bark beetles, which are in ...
