Native budworm, the worst pest of lupins, is a bit of a uiill-o-the-unsp. Some years the native budworm moths go virtually unnoticed. In others, they appear in plague proportions without warning - in these years, the cost to growers in lost yield runs into millions of dollars.
If an early warning system can be developed to predict the extent of moth flights into lupin crops, and this seems possible, major crop losses could be averted.
The Department of Agriculture has started research to develop a system of predicting the size of spring flights of native budworm moth. We need to know how and where the pest survives the summer, autumn and winter, its life cycle, and survival tactics.
