Four colors and 3 types of colored sticky panels were tested for effectiveness in monitoring adults of Megastigmus spennotrophus Wachtl. Panels (gold Rebell) were used to catch chalcids in 44 seed orchard blocks over a 4-yr period. Although the relationship between number of M. spermotrophus captured and subsequent seed damage was weak, a threshold of a cumulative average of 1 female per panel (until 10 d after cone pendency) accurately predicted damage in 89% of the cases. This monitoring system could be used as part of a decision process that includes other factors such as cone crop size, tree phenology, seed value, and the likelihood of a secondary pest outbreak.
