Other claims from this paper (11)
- Observation The oviposition period lasted 6–10 weeks, up to 13 weeks.
- 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.
- 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.
