Forestry Department University of Aberdeen
This paper discusses the species belonging to the genus Evetria Hbn. which are of interest and importance in British forestry. These four species are: E. buoliana Schiff., the pine shoot moth; E. turionana Hbn., the pine bud moth; E. resinella L., the pine resin-gall moth; and E. purdeyi Durr., the pine leaf-mining moth. The main morphological features of all stages of each of the four species are described. Details of the biology, the damage inflicted to individual host trees, and the forest status of each of the species are given and suggestions for control, based mainly on silvicultural techniques, are advanced.
