Efforts to control the moth Lymantria dispar received a boost more than 30 years ago when the fungus Entomophaga maimaiga, native to Japan, was discovered in the United States. Since then, the fungus has played a significant role in curtailing the moth larvae’s attempts to devour large chunks of forest. A new article published in July in Environmental Entomology chronicles the spread of the fungus, both naturally and with the aid of scientists and natural resource managers. Shown here are L. dispar larvae killed by the E. maimaiga fungus. (Photo by Steven Katovich, Bugwood.org)
