“…This life-history strategy enables flies to exploit relatively predictable host plants (Bush 1966). While most Rhagoletis adults emerge during the following season, a proportion of individuals emerges without becoming dormant or after a multi-year or prolonged diapause (Boyce 1931, Dean 1973, Moraiti et al 2012, Rull et al 2016, Neven and Yee 2017). A complex interaction between genes and environment is responsible for dormancy regulation (Feder and Filchak 1999, Dambroski and Feder 2007).…”

The walnut husk fly Rhagoletis completa (Cresson), native to the Midwestern United States and Mexico, is invasive in California and Europe. It is one of the most important pests of walnuts in areas gathering 30% of the world production. Knowledge of life-history regulation is important for the design of management strategies. Research on dormancy has been performed on invasive populations, and not on populations at the southern extreme of its native range. Here, we examined the effect of winter length on fly and parasitoid emergence, survival, and duration of dormancy. Percent emergence was higher for chill periods at 5°C ranging from 8 to 20 wk. No or insufficient chill resulted in low emergence and a significant proportion of individuals in prolonged dormancy (>1 yr). Duration of dormancy was longer for pupae at constant temperatures and a 4-wk chill period than longer winter durations. Dormancy was longer for Mexican than that reported for U.S. populations, suggesting the existence of a latitudinal cline where populations at southern latitudes have evolved slower metabolic rates. Three parasitoid species were found associated with R. completa ( Aganaspis alujai (Wharton and Ovruski) (Hymenoptera: Figitidae), Diachasmimorpha juglandis Muesebeck, and Diachasmimorpha mellea Gahan) (Hymenoptera: Braconidae). Results suggest that rearing of R. completa is possible by subjecting pupae to chill periods between 8 and 20 wk. Overwintering mortality of flies and A. alujai could be further reduced above 5°C. Our findings can contribute for the accurate development of predictive models on invasion potential, development, fly and parasitoid rearing, and biological control.

“…A new generation of adults emerges from early June (Mattsson et al, 2015) onwards to September and adults live for approximately 30 to 40 days (Dean and Chapman, 1973). After emergence, they feed for 7 to 10 days before reaching sexual maturity.…”

“…Eggs hatch after 3 to 7 days, while the emerging larvae take about 2 to 3 weeks to develop within the fruit (Christenson and Foote, 1960), undergoing three larval instar stages. Development times depend on the host species, fruit softness and temperature (Christenson and Foote, 1960;Messina and Jones, 1990;Dean and Chapman, 1973). The larvae tunnel through the flesh of the fruit while feeding, leaving a brown trail and causing the fruit to deteriorate.…”

This pest survey card was prepared in the context of the EFSA mandate on plant pest surveillance (M‐2017‐0137) at the request of the European Commission. Its purpose is to guide the Member States in preparing data and information for Rhagoletispomonellasurveys. These are required to design statistically sound and risk‐based pest surveys, in line with current international standards.Rhagoletis pomonella is part of a species complex of closely related and morphologically similar sibling species that have distinct host plant affiliations.It is most clearly defined by its capacity to infest apples. Import of plants for planting of the major host plants is currently prohibited, while applesare subject to special import requirementsthat aim to prevent the entry of R. pomonella.Nevertheless,the most likely introduction of R. pomonella would be via transport of infested fruit, followed by gradual natural spread. Rhagoletis pomonella is currently absent from the EU and surveys would thus be aimed at substantiating pest freedom. Adult trapping is the preferred survey methodfor detectingR. pomonella. The best timing for trapping is limited to the presence of adults, which generally overlaps with the period in which the host fruit are available.Since the pupae undergo a long dormancy period, adults usually emerge several months following pupation. The primary host for detection surveys in the EU would be cultivated apples, whereas Crataegus species should be includedfor delimiting surveys. Rhagoletis pomonella is expected to be able to become established in most or all areas ofthe EU where apple and hawthorn species grow. Identification of R. pomonella at the species level requires morphological examination of the adults. Identification is most accurate when adultsare obtained from flies reared in apples.
