Abstract

1. In 1930, the Lesser Cabbage White was accidentally introduced into New Zealand, where it is now increasing in numbers and spreading rapidly. In the hope of arresting its spread, and diminishing the damage it causes, the Government of New Zealand decided to import the parasites attacking it in Europe. 2. The present paper comprises an account of the methods used in the collection and shipment of the parasites of Pieris, together with observations on their biology and interrelation; with an attempt to evaluate the effects of the various factors involved in the natural control of the Cabbage Whites in the areas studied.
