Abstract:
A study was conducted to observe the effectiveness of galls by Trichilogaster acaciaelongifoliae on the
vegetative growth of Acacia longifolia subspecies longifolia at six study locations in the Greater Grampians
(GGr) Bioregion of Victoria, Australia during a study period from September 2014–December 2016. The
results of this study have showed that galls formed by Trichilogaster acaciaelongifoliae on Acacia longifolia
subspecies longifolia plants have negative impacts on vegetative growth of Acacia longifolia subspecies
longifolia growing in the native home range of the weed, however it is not sufficient to reduce the invasive
spread of the plant. An integrated weed management approach is required to control the invasive weed
Acacia longifolia subspecies longifolia.
