The citrus gall wasp (Bruchophagus fellis) is a native insect native to coastal regions around the border of Queensland and New South Wales. It has now spread throughout the eastern states, including South Australia and Victoria and has also been found in suburban Perth. The wasp produces lumpy, woody galls around it’s larvae on branches. The galls weaken the trees, reducing fruit size and yield and sometimes causing branch dieback.
Inspired by Gardening Australia, I went with ‘peal and reveal’ to deal with the gall wasp infestation.
