Other claims from this paper (5)
- Observation Bagworm larvae were most abundant on apical and subapical folioles in the upper palm crown.
- Method / resource Upper crown leaves gave the most accurate density estimates with limited foliole sampling.
- Association Accuracy decreased from upper to lower leaves as larval proportions became more variable.
- Method / resource Sampling one palm per hectare gave reasonably accurate estimates of larval density per area.
- Recommendation The one-palm-per-hectare sample size should not be a general recommendation until density effects are investigated.
