Other claims from this paper (15)
- Observation Cedrela leaf phenology varied over time and at minimum 51% of trees retained leaves in a dry period.
- Observation The minimum proportion of foliated Swietenia trees was 87%.
- Observation No Swietenia shoot borer attacks occurred before week 50.
- Observation Initial Cedrela attacks occurred in week 6.
- Observation By week 84, 74% of Cedrela trees had been attacked.
- Observation By week 84, 77% of Swietenia trees had been attacked.
- Association Attack peaks in both tree species coincided with new shoot production.
- Observation Both tree species showed pronounced spatial variation in attack.
- Association Cedrela attacks per block were negatively correlated with available calcium at week 12.
- Association Cedrela height growth was positively correlated with available phosphate.
- Observation Height to first damaging attack varied significantly in both species.
- Observation Only 6% of Cedrela remained undamaged to 3 m by the end of observations.
- Observation Only 0.4% of Swietenia remained undamaged to 3 m by the end of observations.
- Recommendation Shoot borer control should account for seasonal attack and host phenology.
- Recommendation Manipulating soil nutrient status may form part of integrated shoot borer management.
