Small wasp to tackle giant willow aphid

Your views are sought on an application to introduce a wasp into New Zealand to combat the giant willow aphid.

New Zealand Forest Research Institute Ltd - Scion has applied to us to release an organism new to New Zealand. The small parasitic wasp, Pauesia nigrovaria, is part of an effort to control and eradicate the giant willow aphid.

The aphid, Tuberolachnus salignus, can grow 5.8mm in length. It was first reported in New Zealand in December 2013 in Auckland and has spread quickly across the country.

Environmental risks posed by the giant willow aphid include damaging willow trees, which may affect riverbank stability. Bees that consume honeydew made by the aphid produce a sour, unmarketable honey.
