The emerging success of the broom gall mite (Aceria genistae) has people starting to notice galls on other plants too.
Japanese butterfly takes flight
New Zealand’s newest butterfly, the Honshu white admiral (Limenitis glorifica), has established well near the Coromandel Peninsula and is starting to spread its wings in other regions where Japanese honeysuckle (Lonicera japonica) is a target weed.
A lucky break in Uruguay
In February, Hugh Gourlay and Hamish Hodgson travelled to Uruguay to search for biocontrol agents for moth plant (Araujia hortorum) and woolly nightshade (Solanum mauritianum). Unsure of what they would find there, this excursion into the unknown has provided some much-needed breakthroughs.
