Entomological Research

The study of the insects of northern Canada has in the past depended mainly on a very small number of collections obtained by the early explorers, by a few individuals concerned with mapping and other scientific investigations, and by missionaries. The work of Kirby (1837), the reports of the Canadian Arctic Expedition (Hewitt, 1922) and the Fifth Thule Expedition (Henriksen, 1937), and a few short papers represent the main contributions of many years.Organized entomological research in northern Canada began in 1947 as a joint project of the Defence Research Board of the Canada Department of National Defence, and the Divisions of Entomology, Botany and Plant Pathology of the Canada Department of Agriculture. The research programme was divided into three major phases:

The fallowing records represent a supplement to my former publication “Holarctic Elements among the Ichneumoninae of Maine” (Jour. Wash. Acad. Science 43. May, 1953, p. 148-50). They are based mainly on material obtained by the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.

First Time

The following notes report the occurrence in Nova Scotia ofSthereus ptinoides(Germ.) and indicate the distribution in North America of 35 species introduced there from the Old World. Of the Old World species, ten are reported from America for the first time; previous records of two others are probably erroneous. Two, which were named and described inRhyssemusMuls. andScolytusGeoff. as species native to America, are considered introduced, and new synonymy is proposed for them. Confusion of introduced with native species is noted inStethorusWeise andRhinoncusSchön. The material recorded from Newfoundland was collected in the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.

The following contribution to our knowledge of the Ichneumoninae of the boreal parts of Canada and of Alaska is based mainly on material obtained by the Northern Insect Survey, which is a co-operative project of the Canada Department of Agriculture and the Defence Research Board, Canada Department of National Defence.The contribution brings forward 12 new species and subspecies 3 of them being represented by both sexes, 9 by the female sex only. Some arctic species already named before or regarded as holarctic elements will be treated in a separate publication.

In the Northern Insect Survey, sponsored jointly by the Canada Department of Agriculture and the Department of National Defence, the insect fauna of northern Canada was investigated extensively during the summers of 1947-52. The research work has centred on the biting flies and has consisted in large part of taxonomic studies, as a preliminary to biologica1 investigations. In mosquitoes of the genus Aedes, the difficulty of identifying the adult females, particularly those of the black-legged groups, has made biological studies extremely difficult.

During the year 1950 I enjoyed the opportunity of examining the collections of Odonata made by the Northern Insect Survey, a co-operative project of the Canadian Department of Agriculture and the Canadian Department of National Defence. For this privilege I wish to express my thanks to Dr. G. P. Holland and the members of his sraff in the Systematics Unit of the Division of Entomology, particularly to Dr. T. N. Freeman, co-ordinator of the Survev, and Mr. W. A. Brown for “their kindness in providing laboratory facilities during visits to Ottawa and for shipping material to Toronto.

Chicks from 10 broiler strains were randomly allotted and reared at three farms. At 10 weeks of age a random sample consisting of 60 birds of each strain, with an equal number of each sex, was taken at each farm, slaughtered and market graded. At each farm, an official inspector graded the birds according to the standards of the Canada Department of Agriculture. Each bird was graded for the four grade factors: conformation, fleshing, fat and dressing.The number of birds in each grade class was not independent of farm, sex or strain. The 10 strains, ranked on grade scores, tended to rank in the same order at each farm, although the agreement was better for some grade factors than others, and was better when based on males than on females. On a strain rank basis, the grade scores for any one grade factor were not, in general, indicative of the scores for any other grade factor. Also on a strain rank basis, there was a high positive correlation between breast angle and grade scores for fleshing: body weight was not correlated with grade scores for any of the four grade factors, with the possible exception of conformation in the case of males.

Abstract A study was conducted to measure the precision of 2 rapid aflatoxin assay systems in use at 37 peanut buying points during the 1991 harvest season. Aflatoxin laboratories were established at the 37 buying points to analyze peanut samples from all incoming farmers’ stock loads as part of a joint project sponsored by various segments of the U.S. peanut industry and the U.S. Department of Agriculture. Eighteen laboratories were equipped with Neogen’s veratox FSP rapid assay system, whereas 19 laboratories used Vicam’s Aflatest rapid assay system. To monitor the performance of the field laboratories during the project, 3 portions of each of six 27 kg samples of ground peanuts were sent to each laboratory for analysis over a period of 6 weeks. Aflatoxin concentrations ranged from 0 to 300 ng/g when eight 200 g subsamples of each sample were analyzed by liquid chromatography (LC). For the 5 samples contaminated with aflatoxin, relative standard deviations for repeatability (RSDr) for laboratories using veratox FSP ranged from 18.66 to 53.29%, and the relative standard deviations for reproducibility (RSDR) ranged from 22.79 to 59.29%. For laboratories using the Aflatest system, RSDr values ranged from 18.70 to 41.48%, and RSDR values ranged from 23.84 to 47.56%. Horwitz ratios < 2.0 were found for 4 of the 5 contaminated samples for both methods, indicating that the overall precision of the 2 methods used in the project was good. Mean aflatoxin concentrations, as determined with the rapid assay systems, were generally lower than those determined by LC, particularly for more highly contaminated samples. This could not be attributed to instability of aflatoxin in peanut paste, because additional information gathered in the study indicated that the stability of aflatoxin in peanut paste stored for 58 days was good.

Biting Fly

The work of the Northern Insect survey and of the Northern Biting Fly Program brought to light many interesting questions concerning the habits and ecology of northern insects and it seemed desirable to set up more detailed studies that would be continued for a number of years at a chosen site. Through the courtesy of Dr. G. Hattersley-Smith and of the Defence Research Board such a program has been established at Hazen Camp, on the northern shore of Lake Hazen, Ellesmere Island (81° 49′ N., 71° 18′ W.). D. R. Oliver spent seven weeks at Hazen Camp in 1961, and in 1962 a party of six entomologists, a nematologist and a botanist worked there for 2½ months, almost the whole of the growing season. A smaller group is continuing the work in 1963.
