摘要
Tested the hypothesis that feeding by the western conifer seed bug has different effects of Pseudotsuga menziesii seed development at different times during the growing season. Total number of aborted seeds was significantly related to seed bug feeding, especially during early and mid-season treatments. Partially filled seed was significntly related to both seed bug feeding and season, with the seed bug effect increasing during seed development. Seed aborted as a result of seed bug feeding during early stages of seed development was 50% higher than in control cages. -from Authors
