A considerable number of insect species of potential economic importance new to Canada, some being new to North America, have been recorded in the Canadian Insect Pest Survey since new records were reviewed (McNay, 1955). These and others, mainly from 1954 records, are brought together in this paper. Two new mire species are included. Sources of information include Survey reports from officers of the Entomology and Plant Protection divisions, provincial entomologists, and other co-operators; The Canadian Entomologist; The Canadian Insect Pest Review; Proceedings of the Entomological Society of British Columbia; and the Bi-monthly Progress Report of the Forest Biology Division, Canada Department of Agriculture.

The number of new records noted in the Canadian Insect Pest Survey in 1952 was somewhat larger than usual and these and others are brought totether for convenient reference in this paper. Canadian sources of information include Survey reports submitted by officers of the Entomology and Forest Biology divisions, provincial entomologists, and other co-operators; The Canadian Insect Pest Review; Annual Report of the Entomological Sociery of Ontario; The Canadian Entomologist; Annales de l'Acfas; and Proceedings of the Entomological Society of British Columbia. A reference to the collection of the leafhopper Erythroneura flammigera (Geoffr.) on cherry in British Columbia was noted in Science News Letter, a United States publication, and details of the occurrence were obtained from H. H. Ross of the Illinois Natural History Survey.

Forest Biology

The larch sawfly, Pristiphora erichronii (Htg.), is currently considered a major forest insect pest in Canada. At the present time within Canada, the sawfly reacts to parasitism by Mesoleius tenthredinis Morley in two ways. In Manitoba and Saslratchewan the sawfly encapsulates approximately 100 per cent of the parasite eggs deposited, whereas in British Columbia encapsulation rarely exceeds four per cent (Muldrew, 1953). The reasons for the difference in degree of encapsulation are apparently unknown; however, since the origin of the sawfly itself is obscure, the possibility exists that a native species, an introduced species, Or a combination of both may he present, or that geographical or ecological units may have arisen. Studies now under way by officers of the Forest Biology and Entomology divisions are attacking the problem of identity and origin following the pattern established for the European spruce sawfly, Diprion hercyniae (Htg.). In this instance, as with the larch sawfly, parasites were introduced on the assumption that the pest had been introduced from Europe. Critical investigations by Reeks (1941) and Balch, Reeks, and Smith (1941), involving morphological, cytological, and other biological characters, showed that the species occurring in North America was one of two species common in Europe, and previously referred to there as Gilpinia polytoma (Htg.). Balch et al. (1941) showed that D. hercyniae had been introduced into North America.

Myzocallidium riehmi (Börner) was collected from sweet clover at Creston in June, 1957. This is the first time this aphid of potential economic importance has been identified from British Columbia. It occurs throughout the United States (Russell, 1957); in Ontario, Ottawa being near the northern limit of its range (W. R. Richards, in litt.); and was identified for the first time from Manitoba in 1956 (Bird and Robinson, 1957)

New records for non-indigenous species of Hemiptera: Heteroptera continue to be reported from Canada. Schwartz et al. (1991) reported the microphysid Loricula bipunctata (Perris) from Saanichton, British Columbia, and Larivière (1992) reported the occurrence of the nabid Himacerus apterous (Fabricius) from the vicinity of Halifax, Nova Scotia.Asquith and Lattin (1990) recorded the European anthocorid Brachysteles parvicornis (Costa) from New York, and Noodline, New Jersey. Lattin and Asquith (1991) reported additional material of the species from Maine on Picea glauca (Moench) and from Massachusetts on Pinus rigida Mill. With the latter specimens, the oribatid mite Humerobates rostrolamellatus Grandjean was beaten from the trees along with the bug. This is a cosmopolitan mite that occurs on trees and is found in Europe. Pericart (1972), citing Carayon, stated that Brachysteles parvicornis fed upon oribatid mites found on trees. Pericart provided a detailed account of this species of anthocorid in Europe. Little is known of its habits in North America except that it appears to be found on conifers and seems to be associated with the oribatid mite mentioned above. Pericart (1972) reported other hosts in Europe so the bug may be found on non-conifer hosts as well. There is a brachypterous form but, thus far, only fully winged adults have been collected in North America.

We report the presence of two Asian species of larval parasitoids of spotted wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), in northwestern North America. Leptopilina japonica Novkovic & Kimura and Ganaspis brasiliensis (Ihering) (Hymenoptera: Figitidae) were found foraging near and emerging from fruits infested by D. suzukii at several locations across coastal British Columbia, Canada in the summer and fall of 2019. While G. brasiliensis was found in British Columbia for the first time in 2019, re-inspection of previously collected specimens suggests that L. japonica has been present since at least 2016. Additionally, we found a species of Asobara associated with D. suzukii in British Columbia that is possibly Asobara rufescens (Förster) (known only from the Palearctic Region) based on COI DNA barcode data. These findings add to the list of cases documenting adventive establishment of candidate classical biological control agents outside of their native ranges. The findings also illustrate the need for revisiting species concepts within Asobara, as well as host and geographic distribution data due to cryptic and/or misidentified species.

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.

Subjective Synonym

Several species of resin midges (or pine-pitch midges) have been recorded from species of Pinus in North America. These are all at present referred to the genus Retinodiplosis Kieffer 1912; for reasons given below this genus is here treated as a subjective synonym of Cecidomyia Meigen 1803. At least two species of Cecidomyia have been recorded from jack pine, Pinus banksiana Lamb., in Ontario, Manitoba, Saskatchewan and Michigan (Bradlev (1946), Barker and Wong (1948), anonymous (1946), Prentice and Hildahl (1957, 1958) and Mc-Daniel (1938)); they were sometimes determined as Retinodiplosis sp., sometimes tentatively or definitely as R. resinicola (O.S.). Study of specimens of Cecidomyia from P. banksiana collected during the past three years by officers of the Forest Biology Regional Research Laboratories, Canada Department of Agriculture, has shown that three species of the genus occur on this host. All three are described as new in this paper. C. resinicola (O.S.) 1871, originally described from Virginia pine, Pinus virginiana Mill., was not present in this material nor among Michigan specimens from P. banksiana in the U.S.N.M.; it almost certainly does not occur on P. banksiana.
