Mined leaves were collected in commercial and unsprayed (no insecticides) apple orchards of Quebec and Nova Scotia to determine the relative abundance and diversity of parasites of the spotted tentiform leafminer, Phyllonorycter blancardella [Lepidoptera: Gracillariidae]. In Quebec, 29 species of leafminer parasites were recovered, belonging to 7 families: Aphelinidae, Braconidae, Chalcidae, Eulophidae, Ichneumonidae, Pteromalidae and Scelionidae. The most prevalent species were Pholetesor ornigis (67%), Sympiesis marylandensis (11%), S. serviceicornis (7%), Pnigalio maculipes (1.5%), Tetrasticus spp. (1.2%), while all other species accounted for < 1.0%. Pholetesor pedias, a braconid released in 1983 at Frelighsburg, Quebec, was not found in the 1984 and 1985 surveys. In Nova Scotia, 19 parasite species were recovered, belonging to 5 families : Braconidae, Encyrtidae, Eulophidae, Ichneumonidae and Pteromalidae. The most prevalent species were: Pholetesor ornigis (52%), Pnigalio maculipes (14%), Sympiesis serviceicornis (12%), S. marylandensis (9.5%), Sympiesis spp. (5%), Horismenus fraternus (1.8%), Paraleurocerus sp. (1.3%), Stictopisthus flaviceps (1.1%), while all other species accounted for < 1%. Seven and five species of hyperparasites were recovered in Nova Scotia and Quebec, respectively. New records for North America for the spotted tentiform leafminer as a host are : Sticopisthus bilineatus, S. flaviceps, Euderis sp., Pnigalio epilobii, P. pallipes and Paraleurocerus bicoloripes.

AbstractParasitoids of the trivoltine spotted tentiform leafminer, Phyllonorycter blancardella (Fabr.), were studied in Connecticut apple orchards to determine their relative importance, emergence patterns, and seasonal abundance. Sixteen parasitoid species, including 12 eulophids, emerged from mines formed by 4th- and 5th-instar leafminer larvae. The species were primary, secondary, or facultative secondary parasitoids. Five were new records. The braconid Pholetesor ornigis (Weed) was the most abundant in the first and third leafminer generations, and the eulophid Sympiesis marylandensis Girault was the most abundant in the second generation. Ratios of parasitoids to Phyllonorycter spp. were generally higher in samples from unsprayed trees than in those from sprayed trees. Major parasitoids usually emerged 1 to 4 wk before their larval hosts became plentiful. Sweep samples indicated relatively high abundance of one or both major parasitoids during the first and second leafminer generations. Monitoring of parasitoids and the judicious use of insecticides may have a critical role in pest management programs utilizing native parasitoids of leafminers.

This note deals with three European species of Orthotylinae now known to occur in Canada. Pilophorus confusus was discovered in 1976 in Nova Scotia and is reported for the first time from the Nearctic region. Additional distribution records are given for Orthotylus nassatus and O. viridinervis previously reported from North America by Henry (1977) and Henry and Wheeler (1979), respectively. The three species were likely introduced accidentally into this country some time ago with nursery stock importations but remained undetected until recently. They are predatory and overwinter in the egg stage. The adults of the three species are illustrated.

Here we present the first records of Denheyernaxoides from North America: D. americanus, collected from coniferous litter, soil, and moss in Nova Scotia, Canada. These new records significantly expand the known distribution of the species. Denheyernaxoides americanus is redescribed to include Canadian specimens and to rectify discrepancies in the species’ description identified during examination of the holotype. The deutonymph of D. americanus is also described. Sequences, representing a 658 bp region of the mitochondrial cytochrome c oxidase subunit I (COI), were obtained from representative specimens collected in Canada. Comparison of these sequences with those from the Barcode of Life database (BOLD) suggests that a second species of Denheyernaxoides may occur in British Columbia, Canada. A revised key to world species of Denheyernaxoides is provided.

Phloeocharis subtilissima Mannerheim (Coleoptera: Staphylinidae: Phloeocharinae), a Palearctic staphylinid, and Cephennium gallicum Ganglbauer (Coleoptera: Scydmaenidae: Cephenniini) are recorded for the first time for North America from Point Pleasant Park, Halifax, Nova Scotia, Canada. The bionomics of both species are discussed based on European data in addition to new observations of their ecology in Nova Scotia. The role of port cities, such as Halifax, in relation to the introduction of exotic Coleoptera is discussed with examples of other species introduced to North America from this location. The earliest known record of Meligethes viridescens (Fabricius) for North America and the second and third reported locations of Dromius fenestratus Fabricius are also presented.

AbstractThe identity, richness, and abundance of true flies (Diptera) from the nests of three cavity-nesting raptors (Aves) were investigated in northern Nova Scotia, Canada. After fledging, flies were extracted from the nest material using Berlese funnels within an emergence chamber. Thirty-one species/morphospecies from 14 families were collected, including eight new records for Nova Scotia and two new records for eastern North America.

AbstractThe effect of trap color on sticky-trap catches of Pholetesor ornigis Weed was studied in experimental and commercial apple orchards during each of the parasite's 3 yearly activity periods during 1982–1984. Seven enamel and 5 fluorescent paints were compared in 8 trials. There was considerable between-trial variation in the percentage of the total number of P. ornigis caught on a trap of one color. Trap color had a significant effect on the total number of parasites caught. There were no consistent differences in the relative attractiveness of the different colors to males and females. During 1984, males comprised more than 75% of all parasites trapped during each of the 3 activity periods. The sex ratio of the adult population emerging in study orchards during 2 of these activity periods was approximately 1:1.

AbstractThe first investigations of the mite fauna of Sable Island, Nova Scotia, Canada, are reported. Fourteen species have been found. Uropoda orbicularis (Müller) (Uropodidae) and Scarabaspis inexpectatus (Oudemans) (Eviphididae) are newly recorded for North America, Macrocheles nemerdarius Krantz and Whitaker (Macrochelidae) is newly recorded for Canada, and Trichoribates striatus Hammer (Ceratozetidae) is recorded for the first time south of the subarctic zone. Colonization, dispersal, and the zoogeographic origins of the fauna are discussed in the context of the biological, geological, and human history of the island.

Palearctic Species

AbstractThe Nitidulidae and Kateretidae of the Maritime provinces of Canada are surveyed. Forty-eight species are now known to occur in the region. Twenty-six are newly recorded in Nova Scotia and nine are newly recorded on Prince Edward Island. One Palearctic species, Soronia grisea (L.), is reported for only the second time in North America. Six other nonnative species have been intercepted. One new synonym, Glischrochilus sanguinolentussanguinolentus (Olivier, 1790) (= Glischrochilus sanguinolentusrubromaculatus (Reitter, 1873) syn. nov.), is designated. Cape Breton and Prince Edward Island appear to have a depauperate fauna, perhaps reflecting an island-related diminution of species, a comparative lack of collection effort, or a combination of both. An examination of the Nova Scotia fauna indicates several distribution patterns within the province. Introduced species constitute a sizeable component of the region's fauna, with four new introductions being reported here.
