Description

Sequential survey procedures are described for classifying damage to white pine produced by the pine leaf chermid. Damage classes are based on degree of needle stunting, and field procedures for making measurements are given. Survey procedures are also presented for classifying infestation levels of two stages of the insect. These allow prediction of damage levels before damage occurs.
