“…In South Korea, they were believed to have been introduced into the Jeju Island from Japan in 1963-1964 by importing potato seeds and were initially limited to the southern part of the Korean peninsula, which has an average temperature of −8 • C or higher during winter [21]. Now, the potato tuber moth is distributed in most parts of South Korea due to climate change as well as due to its adaptation to the domestic climate [32].…”

Potato tuber moth (Phthorimaea operculella), one of the leading potato-damaging pests in the world, has caused severe damage to potato production in South Korea after its introduction in the 1960s. This study surveyed the field occurrence of potato tuber moth in various sites in South Korea and used the results to validate the CLIMEX model, which spatiotemporally evaluated the potential distribution of potato tuber moths in response to climate change. The potato tuber moths were predicted to appear throughout the country, consistent with the results obtained for potato tuber moths in 96% of the field survey area. In addition, the climatic suitability of potato tuber moths will remain high due to climate change, suggesting a high risk for damage to seasonal potato production from seeding to harvesting. This spatiotemporal assessment of potato tuber moth distribution is expected to aid in establishing control strategies optimized based on time and place.

“…As previously mentioned, in central China, where all three types of EI were high, the occurrence of the potato tuber moth has not yet been officially recorded. However, the potato tuber moth has been officially confirmed in South Korea at the same latitude [58]; thus, the probability of a potato tuber moth invasion in central China is quite high. Particularly, Gansu and Hebei provinces were identified as risky areas.…”

This study evaluated the potential distribution of the potato tuber moth. This species severely impacts global potato production, especially in China and India, which have the world’s largest potato production. We developed two indices considering host plant availability and production in addition to climatic suitability, which was simulated using the CLIMEX model. Thus, three different indices were used to project potential distribution of the potato tuber moth under a climate change scenario: (1) climatic suitability (ecoclimatic index (EI)) (EIM), (2) climatic suitability combined with host plant availability (EIN1), and (3) climatic suitability combined with host plant production (EIN2). Under the current climate, EIM was high in southern India and central to southern China, while EIN1 and EIN2 were approximately 38% and 20% lower than EIM, respectively. Under the Special Report on Emissions Scenario A1B, the potato tuber moth would probably not occur in India, but its distribution could be extended to the north, reaching N47°. The areas with the highest climatic suitability by potato tuber moth based on three indices were Sichuan and Karnataka in response to climate change. These areas require adequate pest control, such as prevention of spread through transport of potato seed or by using cold storage facilities.

“…In Korea, the PTM was first noticed during 1963–1964 in Jeju (having arrived there possibly from nearby Japan), and subsequently found to be initially restricted to the southern parts of South Korea (Aryal & Jung ; Choe & Park ). Recent surveys, however, showed that the PTM had expanded its distribution further to the north (Kwon et al ). Even given this distribution expansion, PTM is still a relatively low priority pest in Korea as the cultivation of the potato and its economic importance have declined (Faostat ).…”

The potato tuber moth (PTM) is an important pest of the potato plant and its tuber. With the expansion of its geographic range, the PTM could be potential threat to the tomato (Solanum lycopersicum L.), a congeneric species of the potato. To assess that risk, we tested larval feeding and development of PTM on leaves of five cultivated tomato varieties namely Moneymaker, Campari, Ailsa Craig, LA3475, E6203 and one wild tomato variety S. pimpinellifolium. PTM larvae accepted all tested plant leaves and developed into adults. Larval development was fastest on the Ailsa Craig variety. Pupae developed fastest on the Moneymaker variety and slowest on LA3475. Host acceptance and survival were highest on Ailsa Craig and lowest on LA3475. The significantly highest male proportion occurred on LA3475 variety. The study showed that PTM could be a potential threat to tomato cultivation which is rapidly increasing in temperate regions owing to climate change.
