In the years following the releases, five of the species have been recorded as being established at various locations. There is no evidence that the sixth species ever became established.

It has been a very effective biological control agent at some locations but not at others. Overall genetic diversity is one parameter that could have an effect on Aphthona establishment at specific locations. We have...
