Abstract:

We analyzed data on total annual Choristoneura fumiferana (Clemens) catch in light traps from 1961 to 1976 at 10 trap locations in the state of Maine. No defoliation caused by C. fumiferana had occurred at these locations between the 1950's and the general state-wide outbreak in the mid-1970's. Inspection of the total annual catch for each site showed that outbreaks were detectable from 4 to 7 years before defoliation occurred. When the data were clustered, outbreaks were detectable 5 years before the first evidence of defoliation within a region. Early detection methods would prove useful in forest management since 8 to 10 years would pass before tree mortality commenced.
