Impacts of a weed biocontrol agent on recovery from water stress in a target and a non-target Hypericum species

Willis, Anthony J; Berentson, Peter; Ash, Julian


1. Biological control agents that impact on non-target native species have limited desirability. Aculus hyperici was introduced into Australia to help control the weed St John's wort Hypericum perforatum, despite indications from pre-release trials that this eriophyid mite could survive and reproduce on a non-target native species, Hypericum gramineum. We used field experiments to explore the probability of A. hyperici colonizing either H. gramineum or H. perforatum in sympatric populations of...[Show more]
