“…An extensive field survey of black hawthorns failed to detect R. pomonella in the PNW aside from areas where the fly was already known to occur (Hood et al 2013 ). A more recent survey found R. pomonella infesting black hawthorn at an isolated site in Troy, Montana (Yee et al 2015 ). However, flies were found infesting only one of 24 trees surveyed across a five-year period, a pattern consistent with a local introduction.…”

Hybridization may be an important process interjecting variation into insect populations enabling host plant shifts and the origin of new economic pests. Here, we examine whether hybridization between the native snowberry-infesting fruit fly Rhagoletis zephyria (Snow) and the introduced quarantine pest R. pomonella (Walsh) is occurring and may aid the spread of the latter into more arid commercial apple-growing regions of central Washington state, USA. Results for 19 microsatellites implied hybridization occurring at a rate of 1.44% per generation between the species. However, there was no evidence for increased hybridization in central Washington. Allele frequencies for seven microsatellites in R. pomonella were more ‘R. zephyria-like’ in central Washington, suggesting that genes conferring resistance to desiccation may be adaptively introgressing from R. zephyria. However, in only one case was the putatively introgressing allele from R. zephyria not found in R. pomonella in the eastern USA. Thus, many of the alleles changing in frequency may have been prestanding in the introduced R. pomonella population. The dynamics of hybridization are therefore complex and nuanced for R. pomonella, with various causes and factors, including introgression for a portion, but not all of the genome, potentially contributing to the pest insect's spread.

“…This interpretation is consistent with data showing low or no R . pomonella infestations in hawthorn or apple fruit in WA and Montana even where hawthorn tree abundance is high [10,12,50,51], although host fruit suitability (not examined here) could also be a factor.…”

Well-adapted and abundant insect pests can negatively affect agricultural production. We modeled the abundance of two Rhagoletis fly (Diptera: Tephritidae) pests, apple maggot fly, Rhagoletis pomonella (Walsh), and western cherry fruit fly, Rhagoletis indifferens Curran, in Washington State (WA), U.S.A. using biologically relevant environmental variables. We tested the hypothesis that abundance of the two species is influenced by different environmental variables, based on the fact that these two species evolved in different environments, have different host plants, and that R . pomonella is an introduced pest in WA while R . indifferens is native. We collected data on fly and host plant abundance at 61 randomly selected sites across WA in 2015 and 2016. We obtained land-cover, climate, and elevation data from online sources and used these data to derive relevant landscape variables and modeled fly abundance using generalized linear models. For R . pomonella , relatively high winter mean minimum temperature, low elevation, and developed land-cover were the top variables positively related to fly abundance. In contrast, for R . indifferens , the top variables related to greater fly abundance were high Hargreaves climatic moisture and annual heat-moisture deficits (indication of drier habitats), high host plant abundance, and developed land-cover. Our results identify key environmental variables driving Rhagoletis fly abundance in WA and can be used for understanding adaptation of insects to non-native and native habitats and for assisting fly quarantine and management decisions.

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 Rhagoletis fausta surveys. These are required to design statistically sound and risk‐based pest surveys, in line with current international standards.Rhagoletisfausta,a clearly defined taxonomic entity, is an important pest of Prunus avium and P. cerasus. Import of plants for planting of Prunus host plants is currently prohibited, while cherriesimport issubject to specific measures aiming to prevent the entry ofnon‐European Tephritidae into the EU. Nevertheless,the most likely introduction of R. fausta would be via transport of infested cherries followed by a gradual natural spread. Rhagoletis fausta is currently absent from the EU and surveys would thus be aimed at substantiating pest freedom. Adult trapping is the preferred survey methodfor detection of R. fausta. Focusing on trapping, the seasonal window for surveillance is limited to the period in which the adult flies are present, which is generally aligned to the period in which ripe host fruit isavailable. The primary hosts for detection surveys in the EU would be cultivated cherry trees. In addition, ornamental and wild Prunus species should be included in delimiting surveys.Rhagoletis fausta is expected to be able to become established inparts of the EU. Identification of R. fausta at the species level requires a morphological examination of the adult flies, and/or molecular tools.The pupae undergo a long dormancy period and adults usually emerge several months following pupation.
