This study describes the biological characteristics of Potato tuber moth (PTM), Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) and its management. It is an economic and cosmopolitan pest of solanaceous crops and weeds including potato, Solanum tuberosum L. Larva can mine the leaf and infest tuber during season and even during the storage. In this paper, we present biology, identification, damage symptom, and different control options of potato tuber moth. Management options cover cultural, chemical, biological and microbial control during season. Three hymenopteran parasitoids are being extensively tested for biological control. Information on Apentels subandinus Blanchard, Orgilus lepidus Muesebeck and Copidosoma desantisi Annecke and Mynhardt (=C. koehleri sensus) was presented. After season, postharvest PTM management issues were discussed relative to human health problems in developing countries where storage facility or condition is not optimum. In Korea, as PTM warning is increasing, further research on management is demanded.
