• Soil population monitoring
  • Started: 1989-05-01
    
  • Method Description: Method 2. Soil populations are monitored using fall soil samples with forced emergence to estimate relative populations. Two bulb-planter soil samples are collected in the fall from 2 and 4 m from each of 5 selected sugar maple trees. Injury to foliage is recorded on associated trees.

• Adult population monitoring
  • Started: 1991-04-01
    Ended: 1991-06-13
    
  • Method Description: Method 1. Adult population levels are monitored weekly using 4 yellow sticky traps located at 3 feet above ground during flight period (April - June). Damage to sugar maple foliage is assessed using 8 trees.
