Abstract  Pheromone traps placed along a transect across the Nelson district from Waimea to Riwaka were used to determine the distribution of three native and one introduced species of leafroller of importance to fruit growing in the Nelson district. The light brown apple moth, Epiphyas postvittana (Walker), was dominant throughout the district. The brownheaded leafrollers, Ctenopseustis obliquana (Walker) and C. herana (Felder & Rogenhofer), and the greenheaded leafroller, Planotortrix excessana (Walker), were each recorded in various proportions at all trap sites. Ctenopseustis obliquana was dominant from Moutere Bluffs to Riwaka, while C. herana was dominant nearer to Nelson.
