Hoy, J.M. 1964a The effects of insects on natural vegetation.. Proceedings of the New Zealand Ecological Society 11: 56-59.

Notes: Within the context of this paper the term "natural" has been taken to mean indigenous as opposed to exotic. This definition has some significance in relation to a discussion of the effect of a scale insect, Eriococcus orariensis Hoy on Leptospermum species in New Zealand.
