Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest risk assessment of Amyelois transitella (Lepidoptera: Pyralidae), the navel orangeworm, for the EU. The quantitative assessment considered two scenarios: (i) current practices and (ii) a requirement for chilled transport. The assessment focused on pathways of introduction, climatic conditions and cultivation of hosts allowing establishment, spread and impact. A. transitella is a common pest of almonds, pistachios and walnuts in California, which is the main source for these nuts imported into the EU. Based on size of the trade and infestation at origin, importation of walnuts and almonds from the USA was identified as the most important pathways for entry of A. transitella. Using expert knowledge elicitation (EKE) and pathway modelling, a median estimate of 2,630 infested nuts is expected to enter the EU each year over the next 5 years (90% certainty range (CR) from 338 to 26,000 infested nuts per year). However, due to estimated small likelihoods of transfer to a host, mating upon transfer and survival of founder populations, the number of populations that establish was estimated to be 0.000698 year −1 (median, 90% CR: 0.0000126-0.0364 year −1 ). Accordingly, the expected period between founding events is 1,430 years (median, 90% CR: 27.5-79,400 year). The likelihood of entry resulting in establishment is therefore considered very small. However, this estimate has high uncertainty, mainly concerning the processes of transfer of the insect to hosts and the establishment of founder populations by those that successfully transfer. Climate matching and CLIMEX modelling indicate that conditions are most suitable for establishment in the southern EU, especially around the Mediterranean basin. The median rate of natural spread was estimated to be 5.6 km/year (median, 90% CR 0.8-19.3 km/year), after an initial lag period of 3.1 year (mean, 90% CR 1.7-6.2 year) following the establishment of a founder population. If A. transitella did establish, estimated median yield losses in nuts were estimated to be in the order of 1-2% depending on the nut species and production system. A scenario requiring imports of nuts to be transported under chilled conditions was shown to provide potential to further reduce the likelihood of entry.

Codling moth (CM Cydia pomonella) is a pest of quarantine concern on apple exports to Asian markets Apples exported to Japan must be fumigated with methyl bromide (MB) and then cold stored Ethyl formate (EF) as an alternative to MB is effective against a range of pests This project investigated the effectiveness of EF to control an internal pest such as CM by determining the responses of key insect stages without fruit and inside apples Trials without fruit in a 2 h fumigation showed that latestage CM eggs and third instar CM larvae were the most tolerant life stages requiring a mean concentration of 134194 EF to achieve 99 mortality but 100 mortality of 4th/5th instar CM larvae Trials with CM in fruit in a 2 h fumigation showed that 113 EF resulted in 534 mortality of 4th/5th CM larvae inside apples Increasing the mean concentration to 24 EF increased the mortality of 4th/5th larvae inside apples to 852

“…For instance, the fumigation period can be high (>24 h), depending on the temperature and target pest [11]. At lower temperatures, PH 3 fumigation must be conducted for longer periods to control the larvae of coding moths (Cydia pomonella L.) and peach fruit moths [12,13]. In an attempt to increase toxicity, to control the larval stage at a low application temperature, and to reduce fumigation time, PH 3 has been applied under O 2 -rich atmospheric conditions (>60%), which reportedly affected the light brown apple moth (Epiphyas postvittana Walker) [14].…”

Phosphine Fumigation Followed by Cold Treatment to Control Peach Fruit Moth, Carposina sasakii, Larvae on “Fuji” Apples Intended for Export

et al. 2022

The fumigation of apples using methyl bromide (MeBr) can cause severe deterioration in fruit quality. Moreover, maintaining the quality of apples during postharvest storage and eradicating pests, especially those involved in quarantine issues, are important for facilitating the export of apples, including the “Fuji” apple (Malus pumila var. “Fuji”) in South Korea. In the present study, phosphine (PH3) fumigation as an alternative to MeBr was found to be more effective for the control of peach fruit moth larvae (Carposina sasakii), which had naturally infested Fuji apples, at a high temperature (25 °C) rather than at a low temperature (5 °C). To achieve the industry requirement of better-quality perishable commodities and meet quarantine guidelines for export, PH3 fumigation at the low temperature (5 °C) was followed by cold treatments at 3 ± 2 °C for 2 and 4 weeks, which led to higher efficacy than was achieved using PH3 at 5 °C alone. Given that chemical treatments, such as treatment with 1-methylcyclopropene, can inhibit ethylene synthesis, low-temperature PH3 fumigation for 72 h followed by 4 weeks of cold treatment could also extend the shelf life of apples and resolve known quarantine issues when used as an alternative to MeBr treatment.
