“…The main economic damage occurs towards the end of the growing season, when moths lay eggs on exposed tubers. Secondary damage by potato tuberworm re-infestation as well as pathogen inoculation during larvae entry also affect potatoes during storage and are considered a problem (Trivedi & Rajagopal 1992. Foliar damage to potato crops usually does not result in significant yield loss, but infested tubers and storage losses may reduce marketability as much as 100%, especially in nonrefrigerated systems (Rondon 2010).…”

The potato tuberworm Phthorimaea operculella (Zeller) is an important agricultural pest that causes significant economic losses to potato growers worldwide. The addition of an effective method of biological control for the potato tuberworm is greatly needed, and is currently unavailable in Brazil. The granulosis virus (Baculoviridae) is a promising biological control agent to protect post-harvest potatoes and in storage from the potato tuberworm. However, the control measure must be economically feasible. Liquid suspensions of a granulosis virus applied alone or in mixture with two commercial neem oil-based products (DalNeem™ and NeemAzal™), and a dry powder formulation of viral granules were evaluated for control of potato tuberworm larvae by treating potato tubers under laboratory conditions. High larval mortality (86.7%) was achieved when DalNeem and virus were applied together at 4 mg of azadirachtin/L and 10 4 occlusion bodies (OBs)/mL, respectively. This combination resulted in ≥50% efficacy in relation to their counterparts alone. Conversely, NeemAzal did not enhance virus effectiveness against larvae of the potato tuberworm. The talc-based virus formulation was used for dusting seed tubers at different concentrations and resulted in 100% larval mortality at 5×10 8 OBs/g. Formulated and unformulated virus provided 50% mortality at 166 OBs/g and at 5.0× 10 5 OBs/mL, respectively. As a result, talc-based virus formulation had a better control efficiency on potato tuberworm than the aqueous virus suspension. The granulosis virus combined with DalNeem at low rates or formulated with talc powder is a viable option to control the potato tuberworm under storage conditions.

“…It occurs widely in Africa, Asia, Europe, Americas and Oceania (Trivedi and Rajagopal, 1992;Vargas et al, 2004;Kroschel et al, 2013). This pest has been reported in tropical, subtropical, and Mediterranean zones (Trivedi and Rajagopal, 1992;Golizadeh and Esmaeili, 2012). The Hungarian introduction of this moth had been already predicted in 1926 (Jablonowski, 1926).…”

The invasive gelechiid moth, potato tuberworm Phthorimaea operculella (Zeller, 1873) was first recorded in Hungary (Komló, Baranya County) and Northern Croatia (Lug, Osijek-Baranja County) in December 2015. This quarantine species has not been reported from Hungary so far and it was known in Croatia only from the coastal region. The occurrence of Ph. operculella in the Carpathian basin is of great concern as this invader is able to cause negative impacts on the Hungarian potato cultivation. This occurrence of the species is one of the northernmost data in Europe so far.

The Potato Tuberworm: A Literature Review of Its Biology, Ecology, and Control

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...
