Macadamia lace bug management and control

Summary

Macadamia lace bugs (Ulonemia spp.) are native to northern NSW and Atherton, Queensland.

Macadamia species and other similar Proteaceae plants are their native host. There are at least four macadamia lace bug (MLB) species, with Ulonemia decoris, which is the most damaging, found in NSW. Once established, MLB populations can increase rapidly and become self-sustaining.
