“…For instance, deeper seed planting, hilling the rows, irrigation, and early harvest are a few of the methods suggested to prevent tuber infestation [10,122,126,139,144]. The use of chemicals, however, is still the main foundation of P. operculella control worldwide [139,[145][146][147]. It is advisable to check with your local extension or government agencies to review which pesticides are allowed to use in your region.…”

Potato (Solanum tuberosum L.) production is challenged by many factors including pests and diseases. Among insect pests, Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), known as the potato tuber worm or potato tuber moth, is considered one of the most important potato pests worldwide. Phthorimaea operculella is a cosmopolitan pest of solanaceous crops including potato, tomato (Solanum lycopersicum L.), and other important row crops. Adults oviposit in leaves, stems, and tubers; immature stage mines leaves causing foliar damage, but most importantly, burrows into tubers rendering them unmarketable. Currently, pest management practices are effective in controlling P. operculella, but the effectiveness depends on many factors that will be discussed later in this chapter. Each section includes up-to-date information related to P. operculella biology, ecology, and control, including origins, host range, life cycle, distribution, seasonal dynamics, and control methods.

“…Deeper seed planting, hilling the rows, irrigation and early harvest are a few of the methods suggested to prevent tuber infestation (Langford and Cory 1932;Langford 1933;Shelton and Wyman 1979a) since these methods discourage egg-laying moths from finding oviposition substrates. The use of chemicals, however, is still the main foundation of P. operculella control worldwide (Shorey et al 1967;Bacon et al 1972;Hofmaster and Waterfield 1972).…”

The potato tuberworm, Phthorimaea operculella (Zeller), is a worldwide pest of solanaceous crops especially devastating to potatoes. Adults mate and lay eggs in foliage or tubers throughout the growing season, preferring foliage over tubers. When foliage has naturally or artificially senesced and/or tubers are accessible, they deposit eggs in or near the eye buds. The larvae mine leaves, stems, and petioles causing irregular galleries, and excavate tunnels through tubers. Foliar damage to the potato crop usually does not result in significant yield losses but infested tubers may have reduced marketability and losses in storage may be up to 100% especially in non-refrigerated systems. The greatest risk of tuber damage occurs immediately before harvest while the crop is left in the field prior to digging; additional damage may occur in storage, if conditions are not maintained properly. Potatoes that are left in the field for any length of time can become infested. The pest is difficult to control and growers rely extensively on the use of insecticides and a variety of cultural practices. After harvest, the insect may continue to develop on tubers or volunteer plants remaining in the field as well as on other solanaceous plants. Incorporation of host plant resistance together with insecticides and appropriate biological and cultural practices may provide the best management options. This review addresses P. operculella bionomics, including origins, distribution, host range, life cycle and life stage behavior; seasonal dynamics; abiotic factors; cultural, biological, and chemical control methods; and host plant resistance.Resumen La palomilla de la papa Phthorimaea operculella (Zeller) es una plaga importante de cultivos de solanáceas en todo el mundo pero especialmente devastadora para la papa. Los adultos se aparean y ponen huevecillos en follaje o en tubérculo a lo largo del ciclo de cultivo, con preferencia de follaje sobre los tubérculos. Cuando el follaje senesce natural o artificialmente y/o los tubérculos están accesibles, las polillas depositan sus huevos en o cerca de los ojos de las yemas. Las larvas hacen minas en las hojas, los tallos y en peciolos causando galerías irregulares, y excavan túneles en los tubérculos. El daño al follaje del cultivo usualmente no resulta en pérdidas significativas de rendimiento, pero los tubérculos infestados pueden tener una reducción en el mercado y las pérdidas en el almacén pueden llegar hasta el 100% especialmente en sistemas no refrigerados. El mayor riesgo de daño en los tubérculos se presenta inmediatamente antes de la cosecha mientras el cultivo está en el campo antes de ser cosechado y transportado. Se puede presentar daño adicional en el almacén si las condiciones no se mantienen apropiadamente. Las papas que se quedan en el campo por tiempo prolongado pueden ser infestados. La plaga es difícil de controlar y los productores confían extensivamente en el uso de insecticidas y en una variedad de prácticas culturales. Después de la cosecha, el insecto pue...
