Abstract
The number of native budworm caterpillars in a crop is the major factor determining potential economic damage from the pest. Table 1 was generated with results from department trials to provide an estimate of potential loss from native budworm damage.
Crop loss (kilograms per hectare (kg/ha)) for each caterpillar netted in 10 sweeps (or found per square metre (m2 )) is shown in Table 1. One caterpillar netted in 10 sweeps is equivalent to about 20,000 caterpillars/ha for most pulse crops, assuming an even distribution over the crop
