Book Description
Excerpt from Forest Insect and Disease Conditions in Alaska Ground and aerial surveys detected significant blotch miner damage on hectares of quaking aspen near Fairbanks. Before last summer, damage caused by this miner was practically nonexistent. It was not until 1977 that the causal agent was identified as L. Ontario. Likewise, a related but unidentified species of Lithocol/etis caused considerable mining on alder in and around Fairbanks. Efforts will be undertaken next year to monitor the effects of these hardwood blotch miners. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
