Observation The seed feeder accepted a broad range of flowerhead developmental stages.
Observation On average the seed feeder attacked half of available flowerheads.
Observation Attacked flowerheads contained 3.9 to 4.8 larvae per head on average.
Association Apical flowerheads were attacked more than nonapical heads.
Observation Host specificity data indicated that the seed feeder lives monophagously on the plant.
Recommendation The authors proposed complete host range screening.
Observation Each larva required 21 seeds on average to complete development.
Observation The seed feeder predominantly destroyed apical heads.
Observation Resource utilization of individual flowerheads averaged 35%.
Observation Immature seed feeders had mortality as high as 91.1%, mainly due to parasitoids.
Mechanism The authors expected higher attack and seed reduction without natural enemies.
