Biological control agent – release approved

March 14, 2019

Good news to eucalypt growers! The EPA has approved the release of a parasitoid wasp for the biological control of the Eucalyptus tortoise beetle, Paropsis charybidis. The approval has come after several years of containment trials by a Scion team led by Dr Toni Withers. Paropsis beetles are major defoliators of some eucalypt species.
