AbstractA spotted tentiform leaf miner, often present during recent years in large numbers in apple orchards in the Maritime Provinces of Canada, is identified as Lithocolletis blancardella Fabr., a species common on apples in Europe. Recent collecting indicates that the species occurs widely in Eastern Canada and the northeastern United States. Diagnostic characters, especially those of the male genitalia, are compared with those of specimens identified as L. crataegella Clem. and L. propinquinella Braun, two similar species which commonly occur on apple and black cherry respectively.

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.

First Report

Isoetes acadiensis Kott is a plant of the Maritime provinces of Canada and the northeastern United States. In the Chesapeake Bay region, this quillwort has previously been misidentified as Isoetes riparia Engelm., Isoetes saccharata Engelm., or Isoetes saccharata var. reticulata A.A. Eaton. Isoetes × carltaylorii hyb.nov. is the hybrid between I. acadiensis (2n = 44) and Isoetes engelmannii A. Braun (2n = 22). This is the first report of a hybrid with I. acadiensis. An apparently sterile triploid (2n = 33), this rare plant of freshwater tidal marshes has the predicted range of sizes and megaspore features of a hybrid. This brings to 14 the number of interspecific quillwort hybrids described from North America since 1985. Key words: Isoetes saccharata var. reticulata, Isoetes riparia, Isoetes saccharata, megaspores, tidal freshwater rivers.

AbstractColeophora deauratella Lienig and Zeller is reported for the first time in North America. This casebearer species was introduced accidentally from Europe almost 30 years ago but remained unrecognized. It currently is known from eastern Canada and northeastern United States. Larvae feed on seeds of red clover, Trifolium pratense L. Diagnostic characters of the larval case and the adult, as well as features separating C. deauratella from two similar casebearer species, are presented.

AbstractTwo exotic species of Xyleborus (Coleoptera: Scolytidae) of Asian origin have recently been detected in the United States. Xyleborus pelliculosus Eichhoff has been collected in Pennsylvania and Maryland, and X. atratus Eichhoff from Tennessee, Georgia, Maryland, Virginia, and West Virginia. Descriptions of both species and a revised, illustrated key to members of the genus Xyleborus in eastern North America are presented. An explanation is proposed for the large numbers of recent introductions of exotic ambrosia beetles from eastern Asia into eastern North America.

Grape Leafhopper

Abstract Eastern grape leafhopper, Erythroneura comes (Say), is a key pest of grapes (Vitales: Vitaceae) in the central and northeastern United States and eastern Canada. This native insect uses its piercing-sucking mouthparts to puncture the mesophyll cells of leaves and suck out the contents, thereby reducing the quality and quantity of fruit. Eastern grape leafhopper has been reported as a vineyard pest for nearly 200 yr and is one of several Erythroneura spp. that feed on grapes in North America. Overwintered adults become active in early spring and may feed on grasses, weeds, and other plants before feeding on grapevines. Although eastern grape leafhopper has an extensive host range, it is only known to oviposit on wild and cultivated grapes. This multivoltine species can outbreak periodically, which has generated much research into improved monitoring and integrated pest management strategies employed throughout its native range. In this review, we describe the biology, life history, population dynamics, and phenology of eastern grape leafhopper and provide a historical account of monitoring and management strategies for this important vineyard pest.

Adelges Piceae

The balsam woolly aphid, Adelges piceae (Ratz.), causes serious damage to balsam fir, Abies balsamea (L.) Mill., in Eastern Canada. It was introduced from Europe before 1900 (Balch, 1952) and has also become established in the northeastern United States. In continental Europe A. piceae is common on Abies alba Mill. but is not so serious a pest as in Canada. It has an extensive complex of insect predators in both Canada (Balch, 1934) and Europe (Delucchi, 1954). Balch (1934, 1952) found those in Canada inadequate as control agents. Some of the predators of Pineus pini Koch and Pineus strobi (Htg.) studied by Wilson (1938) in England, and recommended for introduction to new areas, were imported to Canada and released against A. piceae. Predators were first introdnced from Ensland in 1933 and later from continental Europe beginning in 1951.

Abstract This study investigates the relationship between earthquake magnitude and the size of damage areas in the eastern and western United States. To quantify damage area as a function of moment magnitude (M), 149 MMI VI and VII areas for 109 earthquakes (88 in the western United States, 21 in the eastern United States and Canada) were measured. Regression of isoseismal areas versus M indicated that areas in the East were larger than those in the West, at both intensity levels, by an average 5 × in the M 4.5 to 7.5 range. In terms of radii for circles of equivalent area, these results indicate that damaging ground motion from shocks of the same magnitude extend 2 × the epicentral distance in eastern North America compared to the West. To determine source and site parameters consistent with the above results, response spectral levels for eastern North America were stochastically simulated and compared with response spectral ordinates derived from recorded strong ground motion data in the western United States. Stress-drop values of 200 bars, combined with a surficial 2-km-thick low velocity “sedimentary” layer over rock basement, produced results that are compatible with the intensity observations, i.e., similar response spectral levels in the east at approximately twice their epicentral distance in the western U.S. distance. These results suggest that ground motion modeling in eastern North America may need to incorporate source and site parameters different from those presently in general use. The results are also of importance to eastern U.S. hazard assessments as they require allowance for the larger damage areas in preparedness and mitigation programs.

This chapter describes two invasive crane fly species which are pests of turfgrass, particularly in the northwestern and northeastern United States, as well as southern British Columbia and the metropolitan Toronto area in Canada. The European crane fly and the common or marsh crane fly, order Diptera, family Tipulidae, subfamily Tipulinae, have elongated maxillary palpi that distinguish members of this subfamily from other subfamilies. Larvae of invasive crane flies are sometimes called leatherjackets, in part because the pupae are leathery in appearance. Invasive crane flies have a relatively limited distribution in North America, but can cause considerable damage on golf courses, lawns, athletic fields, and sod farms, as well as forage fields and hayfields. The chapter also looks at the frit fly, which belongs to the family Chloropidae.
