  • a Scale of 1-5, where 1 is hollow and 5 is completely solid.

  • b Visual assessment of percent cut stems in the field.

  • c Mortality is calculated as total larval mortality in the stem minus the number of large larvae killed by parasitoids divided by the total number of infested stems.

  • d Laboratory assessment on collected plots at the time of dissection.
