Grassland farming is the basis of our primary production and insetit pests constitute one of the factors which limit or decrease that production. A survey of the relative importance of different pest species and of the means available for their control should serve a useful purpose. Such a stocktaking will help in comparing the pasture pest situation in New Zealand with that in other countries, and in indicating some of the overseas pests whose accidental establishment in New Zealand could be potentially very serious.
