Identification Guide to Lepidoptera Larvae Intercepted on Trade Pathways

Abstract

This Lepidoptera larval identification guide was prepared using invertebrate interception data collected from fresh produce imported into New Zealand covering pre- and post-border interceptions from 1990—2008. Imports into New Zealand include a wide range of fresh produce from all over the world and these commodities are essentially the same as those imported into Pacific Island countries. The guide provides information on the recognition of common interceptions as well as economically significant pests associated with fresh produce frequently imported into and exported from Pacific island countries. Moreover, the scope was expanded to include some potential interceptions, NZ natives, and other taxa of importance. The keys are simplified using basic terms where possible and contain multiple photographic and diagrammatic illustrations. Thus the guide is an ideal identification tool for training and to assist biosecurity officers throughout the Pacific with informed decision making.
