This CD-ROM contains an interactive identification guide and is a source of information on economically important tortricids in Europe and Asia for all practicing entomologists working in agriculture, forestry and horticulture, and for those interested in plant protection and quarantine. It contains a pictorial key to the males and females of 188 species that represent the primary and secondary parasites on the economically most important crops of Eurasia. Further, detailed information is given on their life histories, host plants, distribution, parasitoids and attractants. Notes on related non-pest species and diagnostic characters to distinguish them from economically important species are also included. This work was compiled using the most recent literature from renown experts in the field and using unique photographs provided by numerous institutes.
