Winter Temperatures

The European pine shoot moth, Rhyacionia buoliana (Schiff.), was first discovered in North America on Long Island, New York, in 1914 (Busck, 1914). Since that time it has spread throughout most of the northeastern United States, becoming one of the most important insect pests of pine plantations. In Ontario, it was first discovered in the Toronto area (McLaine, 1926) and since that time has dispersed throughout southern Ontario, appearing regvlarly south of a line from the southern end of Gcorgian Bay to a point just east of Lake Ontario (Fig. 1). Isolated occurrences of the shoot moth have been reported north of this line but these have been short-lived on small plantation trees, or have persisted in cities and towns on ornamentals protected by snow cover during the winter. The continuous distribution of the insect has remained relatively static since 1951, and it appears that the northern limit of its range in Ontario has been reached.

Ams Dates

AbstractA radiocarbon date of A.D. 1070 ± 60 was linked to the remains of maize (Zea mays), beans (Phaseolus vulgaris), and squash (Cucñrbita pepo) at the Roundtop site in the Susquehanna River valley of New York by William Ritchie in 1969 and 1973 publications. This date established the presence of beans in the Northeast at an earlier time than in most other areas of the eastern United States, where they are generally rare before A.D. 1300. Subsequently beans have been reported in pre-A.D.1300 contexts from at least eight other sites in the Northeast. Recent calibrated AMS dates on beans from Roundtop are no earlier than A.D. 1300 (Hart 1999a). Given that the original Roundtop date was responsible for the acceptance of early beans in the Northeast, the AMS dates suggested that beans may not become archaeologically visible there until ca. A.D. 1300. AMS dates on beans from four other sites, reported here, substantiate the Roundtop results. Beans and by extension maize-beans-squash intercropping are not evident in the Northeast before ca. A.D. 1300.

Eurasian Species

The frequency of the middorsally striped morph of Rana sylvatica in Ontario and Manitoba varies from absence in southern Ontario to 80% on the coast of Hudson Bay, with a general value of 20–30% in the boreal forest, a rise to 50% on the forest–grassland ecotone in southern Manitoba, and a decline westward to 20% on the edge of the prairies. This morph is rare in the northeastern United States and Maritime Canada. The suggested relationship between its frequency and the "grassiness" of the background on which predators view it is reexamined, and it is suggested that a linkage with earlier transformation as demonstrated in Eurasian species may explain certain anomalies.

Abstract Chronic wasting disease (CWD) is a prion disease that affects both wild and captive cervid populations. In the past 45 y, CWD has spread from northern Colorado to all bordering states, as well as the midwestern United States (Midwest) and northeastern United States (Northeast), Canada, and South Korea. Because CWD is a relatively new issue for wildlife management agencies in the Northeast, we surveyed a representative (e.g., cervid biologist, wildlife veterinarian) from 14 states to gain a better understanding of state-specific surveillance measures. Between 2002 and 2012, New York (37,093) and Pennsylvania (35,324) tested the greatest number of harvested white-tailed deer Odocoileus virginianus in the Northeast. Additionally, the 14 states surveyed have tested 121,730 harvested deer, or approximately 15,216/y, since CWD was first detected in 2005. The most common tissues used by agencies in the Northeast for testing were retropharyngeal lymph nodes, which have been determined to be the most reliable in detecting CWD in cervids. Understanding CWD surveillance efforts at a regional scale can help to provide guidance for the development of new surveillance plans or the improvement of existing ones. Furthermore, collaborations among state and regional agencies in the Northeast may attempt to identify deficiencies in surveillance by state or subregion.

Oecanthus Nigricornis

AbstractThe conopid fly Stylogaster neglecta Williston (Diptera: Conopidae) is a parasitoid with no known host. We report this species as the first recorded dipteran parasitoid of Oecanthus nigricornis Walker (Orthoptera: Gryllidae) (black-horned tree crickets). We reared field-collected O. nigricornis juveniles over several months in 2017 and found that larval S. neglecta emerged from them during late July into August. We estimated the incubation period for S. neglecta larvae to be around 30 days based on the length of time it took for them to emerge from the host and pupate (subsequently all hosts died). We documented several cases of multiple parasitism. In 2018, we dissected O. nigricornis sampled from four sites across southern Ontario, Canada and upstate New York, United States of America and found that the percentage of juvenile O. nigricornis parasitised ranged 2–39%. Further sampling will be necessary to determine whether this variation represents consistent population differences or between-year variation in parasitism.

Additional Control

Two introduced windgrass species have become crop weeds in North America. Common windgrass is a major weed of winter cereals in Europe and was first documented in North America in the early 1800s. It is a weed of roadsides and waste areas in the northeastern United States and in winter grain fields of southern Ontario and Michigan. Interrupted windgrass was first reported in North America approximately 90 yr ago; it is adapted to more arid sites than common windgrass and is distributed predominantly in the northwestern U.S.A. During the past 10 to 15 yr, interrupted windgrass has adversely affected winter grain and grass seed producers in the Pacific Northwest due to additional control costs.

A fragmented radius of a late Pleistocene peccary, Platygonus compressus Le Conte, has been recovered near Old Crow, Yukon Territory, Canada. The known northern limit of the species is thus extended approximately 3000 km, from the northeastern United States to north of the Arctic Circle in Pleistocene Beringia, and confirms the cold tolerance of the species. The small size of the specimen supports a theory that small size in P. compressus is correlated with periglacial environment. Although the age of the specimen is uncertain, a mid-Wisconsin age is inferred on the basis of availability of a route of dispersal to Beringia and palaeoecological evidence which suggest a largely treeless tundra dominated by sedges and grasses, but with a rich herb component.
