Apple Ermine Moth

The apple ermine moth, Yponomeuta malinellus Zeller, is a univoltine pest species that defoliates apple, Malus domestics (Borkh) (Rosaceae), in the temperate region of the Palaearctic. First instars overwinter within a communal hibernaculum beneath the covering of the egg batch (Kock 1998). In spring, larvae emerge to initially mine apple leaves and subsequently feed externally within a communal tent (Menken et al. 1992). During heavy infestations, the communal tents may envelop the entire apple tree, resulting in total defoliation (Parker and Schmidt 1985). There have been several accidental introductions and subsequent eradications of the apple ermine moth in eastern North America (Hewitt 1917; Parker and Schmidt 1985) but, by 1989, the pest was found in the Fraser River Valley in British Columbia, in Whatcom county, Washington, and in northwestern Oregon (Antonelli 1991; Unruh et al. 1993).

The geometrid moth Hemithea aestivaria (Hübner, 1789) was introduced from Europe to North America, first detected in British Columbia in 1973. Until 2019, its North American range was limited to a restricted area of the Pacific Northwest. Here, we report on the first records of H. aestivaria for eastern North America from three widely separated urban centers in eastern Canada during 2019-2020.

Eurasian water milfoil, Myriophyllum spicatum Linnaeus, was introduced into eastern North America late in the nineteenth century. It has spread and developed into a major aquatic weed in many areas of the United states and Canada (Aiken et al. 1979; Reed 1977). In British Columbia, it was first observed in the Vernon Arm of Okanagan Lake in 1970 and had spread to all major 1,akes in the Okanagan Valley by 1976 (Newroth 1979).

AbstractPhyllonorycter elmaella n sp. is described from specimens reared from ptychonomous mines on the lower surface of apple leaves from the vicinity of Vancouver, B.C. The species is compared with European P. sorbi (Frey) and the Japanese P. sorbicola (Kumata) n. comb., to which it is more closely similar than to species attacking apple and related trees in Eastern North America. The species has three generations a year and overwinters in the pupal stage.

Red Squirrel

Breeding in the red squirrel, Tamiasciurus hudsonicus (Erxleben), in southern British Columbia differed in some respects from that reported in eastern North America. The period during which males were capable of breeding varied from 2 to 6 months, and their reproductive organs showed only a single peak in size each year. All breeding females produced two litters in 1966, but only one litter in 1967. Females did not breed during the year of their birth, and, in 1967, some did not breed as yearlings. February appeared to be the earliest date for the onset of breeding in southern British Columbia. The timing of breeding may be influenced by weather conditions.

Microfossil Assemblage

Spores, pollen grains, and other microfossils are described from the Skonun Formation of Queen Charlotte Islands, situated off the western coast of British Columbia. The microfossil assemblage, apparently late Miocene to early Pliocene in age, is analyzed and compared with both other fossil floras and the extant flora. Results indicate the presence of distinctive genera and species, some of whose living equivalents are found only in Asia, Central and South America, or Eastern North America. The phytogeographic and paleoecologic implications of the microfossils are discussed, and reconstructions are attempted for both the climate and the physiography during the time of deposition.

Future Direction

Abstract In September 2019, destruction of a Vespa mandarinia Smith 1852 nest was reported for the first time in North America in Nanaimo, British Columbia, Canada. In December 2019, the Washington State Department of Agriculture also confirmed the first detection of an adult specimen of V. mandarinia in the United States, in Whatcom County, Washington. Vespa mandarinia is the largest hornet species and is a known predator of several insects, including the European honey bee (Apis mellifera) (Hymenoptera: Apidae) (Linnaeus, 1758). The establishment of V. mandarinia in North America poses a serious threat to apiculture, and this species is considered an actionable quarantine pest. Here we report details of the first detection of this species in the United States and use genetic sequence data obtained from five specimens across the globe to estimate differences in origin of the Canadian and U.S. detections. The full mitochondrial genomes of four V. mandarinia specimens representing different geographic locations were sequenced and compared with an existing reference genome. A maximum likelihood tree using 13 protein-coding regions from mitochondrial DNA suggests that the Canada and U.S. specimens are from two separate maternal lineages. A large-scale survey is currently underway to assess the level of Asian giant hornet establishment in both countries and to determine the future direction of eradication efforts.

Pollinating Insects

The Asian giant hornet (AGH, Vespa mandarinia) is the world’s largest hornet, occurring naturally in the Indomalayan region, where it is a voracious predator of pollinating insects including honey bees. In September 2019, a nest of Asian giant hornets was detected outside of Vancouver, British Columbia; multiple individuals were detected in British Columbia and Washington state in 2020; and another nest was found and eradicated in Washington state in November 2020, indicating that the AGH may have successfully wintered in North America. Because hornets tend to spread rapidly and become pests, reliable estimates of the potential invasive range of V. mandarinia in North America are needed to assess likely human and economic impacts, and to guide future eradication attempts. Here, we assess climatic suitability for AGH in North America, and suggest that, without control, this species could establish populations across the Pacific Northwest and much of eastern North America. Predicted suitable areas for AGH in North America overlap broadly with areas where honey production is highest, as well as with species-rich areas for native bumble bees and stingless bees of the genus Melipona in Mexico, highlighting the economic and environmental necessity of controlling this nascent invasion.

Oulema Melanopus

AbstractCereal leaf beetle, Oulema melanopus L., is an invasive pest insect of small grain cereal crops, particularly oat, wheat, and barley. The first report of cereal leaf beetle populations in North America came from Michigan in 1962. Surveys indicate that populations have become established throughout eastern North America from Ontario to Alabama and in northwestern North America from Utah to southern British Columbia. The establishment of O. melanopus in western North America has raised concern that its presence is a potential risk to the Canadian cereal industry, especially in the prairie ecozone of western Canada, where up to 10 million hectares of cereal crops are grown annually. Field surveys to date have indicated that O. melanopus has not yet become established in this region. A CLIMEX™ model for O. melanopus in North America was developed, based on climate and ecological parameters, and validated with actual distribution records. The actual distribution of O. melanopus in eastern North America matched the predicted distribution well. The model predicts that, once introduced, O. melanopus would readily survive in the cereal-growing areas of western Canada and present a significant risk to cereal production. The potential for establishment of O. melanopus in the prairie ecozone of western Canada substantiates the efforts by regulatory agencies to prevent accidental introduction of this pest species.
