Which species of Tortricid leafroller do I have in my vineyard?Leafrollers other than LBAM found in grapevine canopies for the first time

摘要

It is commonly regarded that light brown apple moth, Epiphyas postvittana (Lepidoptera: Tortricidae), is the key insect pest that causes economic damage in Australian vineyards. Larval LBAM damage leaves, flower clusters and berry skins. Damaged skinsprovide infection sites for Botrytis cinerea and other bunch moulds, which result in a reduction in fruit quality and yield losses (Ferguson 1995). Annual national losses from LBAM and related bunch rots were estimated to be $70 million per year in Australia (Scholefield and Morison 2010) and is likely to be higher as these figures are nearly a decade old.
