Abstract

AbstractSeven species groups of Dioryctria are defined on a combination of external and genital characters. Three American species, Dioryctria rossi Munroe, D. auranticella (Grote) and D. disclusa Heinrich, are referred to the auranticella group. Four Asiatic species are also referred to this group. These are D. okui Mutuura, D. castanea Bradley, D. pryeri Ragonot (= Salebria laruata Heinrich), and D. yiai n. sp. All the species feed on conifers. All except D. okui feed on pine, either cones or shoots, or both; D. okui eats the foliage of spruce.
