What's New in Biological Control of Weeds? Issue 65
August 2013
In this issue
Scottish ‘Laddies’ Flown in for Genetic Rescue
A novel experiment is underway to improve the vigour of heather beetles (Lochmaea suturalis).
Finding a Perfect Match
Our project to develop biocontrol for pampas (Cortaderia spp.) has thrown up a few surprises.
Ginger Biocontrol Edges Closer to Fruition
Research aiming to biologically control wild ginger (Hedychium gardnerianum) is now in its fifth phase and prospects of success remain promising. Since our last update (Issue 61), the team at CABI Europe-UK have continued to make progress.
Manchurian Wild Rice, Coming to a Wetland near You?
Manchurian wild rice was accidentally introduced into New Zealand via soil ballast from ships, and it is now considered a weed around waterways in Northland where it grows up to 4 m tall.
Value of Silver Leaf Fungus Explored
No-one wants their drinking water contaminated with chemical herbicide residues. Nonetheless, we need to control weeds that grow in and beside water (riparian weeds).
Mite We Have the Answer for Old Man’s Beard?
Three agents have already been released to control old man’s beard (Clematis vitalba) (OMB) but none have been able to do the job for different reasons.
Spring Activities
Most biocontrol agents become active during spring, making it a busy time of year for biocontrol activities.
Biocontrol Agents Released in 2012/13
97 releases made to control broom, tradescantia and wolly nightshade.
Who’s Who in Biological Control of Weeds?
Summary of control agents, how they function and how well they are working to control their target weeds.
