  2. Chilean Flame Creeper Beetle Passes the Test

    Chilean flame creeper is a climbing vine that has become an important environmental weed in Southland, Otago and Canterbury. It is present in the lower regions of the North Island, but it is only considered a minor weed there. A biological control programme was initiated in 2021 following the serend...

  3. Yellow Flag Iris Flea Beetle Touches Down

    With the new year a new candidate biocontrol agent arrived at our insect containment facility at Lincoln.

    We are excited to report that our most recently introduced biocontrol agent, the Sydney golden wattle bud-galling wasp, has shown positive signs of establishment following its release last summer.

  5. Variability in Herbivory Shows Patterns, and it Matters
