This paper presents data on the biology and economic importance4 of the orange tortrix, Argyrotaenia citrana (Fernald), which is the most important of several species of small moths, the larvae of which have caused damage for many years to the orange and occasionally to other citrus fruits in southern California. Other species considered to a lesser extent, are Holcocera iceryaeella (Riley), Platynota stultana Walsingham, and Pyroderces rileyi (Walsingham).
The orange tortrix is a member of the Tortricidae, which is a family of small Lepidoptera including the leaf-rollers and bud moths. The species was described and placed in the genus Tortrix by Fernald in 1889, but its generic position has been somewhat uncertain in recent years. The author follows August Busck5 of the United States Department of Agriculture, who places it in the genus Argyrotaenia.
(Coquillett (1894))6 suspected that the orange tortrix was imported from some of the Pacific Islands. Prior to the inauguration of the rigid plantquarantine service in California, it could easily have been brought into this country in the egg, larval, or pupal stage on imported plants.
