Scarab beetle infestation causing slow tree decline
2020 | NSW DPI, Bright J
Fact Sheet
Scarab beetles are present in all macadamia growing regions of Australia. Reports of scarab beetles in the 2013–14 macadamia season and again in 2017 and now 2020 suggest that they appear to be a dry weather pest or at least a pest that is seen most when dry conditions prevail.
Industry help is required to understand the extent of this problem.
