Beggs, J.R. 2000. Impact and control of introduced Vespula wasps in New Zealand. Hymenoptera: Evolution, Biodiversity and Biological Control. eds. A.D. Austin, M. Dowton. CSIRO publishing. pp 404–409.

This paper summarises the introduction of social Vespula wasps to New Zealand, and the impact that they are having, particularly in honeydew beech forests. There is also a summary of wasp control in New Zealand, dealing with two main strategies: poison-baiting for short-term, localised control; and biological control for self-sustaining, widespread control.
