Spread of fungus-farming beetles is bad news for trees
Date:7/13/2011

North Carolina State University researchers have found that a subset of fungus-farming ambrosia beetles may be in the early stages of a global epidemic threatening a number of economically important trees, including avocados, poplars and oaks.

"Only about 12 species of ambrosia beetle are creating problems so far, but there are thousands of other species in the world, many of which could be devastating to any number of tree species," says Dr. Jiri Hulcr, a postdoctoral research associate at NC State and lead author of a paper describing the research. "Dutch elm disease is also caused by a fungus that is spread by beetles, and it ravaged the elm population in North America and Europe."

Ambrosia beetles tunnel into trees, creating chambers that they fill with fungal conidia effectively "seeds" that grow into fungal crops that the beetles rely on for food. Ambrosia beetles target dead wood when in their native habitats. However, some species have been found to target living trees when transported into new environments.

For example, the redbay ambrosia beetle is originally from southeast Asia, where it colonizes dead wood exclusively. But since the species was accidentally introduced into the southeast United States it has begun colonizing living redbay and avocado trees posing a significant threat to Florida's avocado industry.

The ambrosia beetles kill trees because their fungus triggers a strong response from the tree's own immune system. The tree effectively cuts off its own water supply in an attempt to thwart the invasive fungus, and then dies of thirst.

The researchers found that, in addition to the redbay ambrosia beetle, problems with invasive ambrosia beetle species have affected oak trees in Japan; poplars in Argentina and Italy; and various other tree species in Korea, Israel, Thailand and the United States from Ohio to Florida. The various species are spread primarily through international commer
