Until now this family has been known only through one species Nymphomyia alba Tokunaga, found in Japan in 1932. The specimens taken in New Brunswick and shown in the exhibit differ strikingly from Nymphomyia and represent a new genus.With one exception, the thirty-eight individuals recovered from collections to date, were taken by fine-mesh screens set in the rapids of a small stream. These had been placed to catch casualties among aquatic insects drifting downstream following spraying of the adjacent forest with DDT. The spraying operation was of an experimental nature, carried out cooperatively by Forest Protection Limited, the Chemical Control Section, Canada Department of Forestry and the Fisheries Research Board of Canada.

AbstractThe new genus Archepandemis, with type-species Parapandemis borealis Freeman, 1965, is described. Two new species, A. coniferana from British Columbia and Alberta and A. morrisana from New Brunswick, are distinguished from A. borealis by characters of maculation and especially of male and female genitalia.

Active Selection

Food in stomachs of young Atlantic salmon from the Northwest Miramichi River, N.B., changed following aerial DDT spraying of the surrounding watershed. Before spraying, young salmon typically ate immature aquatic insects, fry (underyearlings) concentrating on Diptera and small Ephemeroptera, and parr (overyearlings) on Diptera, Trichoptera, and all sizes of Ephemeroptera. Reduction of all aquatic insects by DDT was soon followed by resurgence of Chironomidae and other Diptera, and surviving fry fed heavily on these; parr fed on Diptera but also ate snails, worms, and fish, previously unimportant in their diet. Five years after the last spraying the pre-spray complexity of young salmon food was being approached. Trichoptera were slowest of the major fish-food types to reappear in stomachs.In fry stomachs Ephemeroptera, and in parr stomachs Ephemeroptera and Trichoptera, were relatively more abundant than in the surrounding stream fauna. Greater availability of these insects and active selection by fish are discussed as possible causes of these relationships.

Harmful Effects

No harmful effects on aquatic insects were detected in two New Brunswick streams after forest spraying with phosphamidon [Formula: see text] in 1962 and 1963. Comparison of one pre-spray and two post-spray series of bottom samples showed no reduction in number of orders (and families in the case of Diptera) and no abnormal decline in the number of individuals. In numbers and variety of insects emerging daily into stream cages and of insects drifting onto vertical screens in the streams, no changes were attributable to phosphamidon.

New Genus And Species

A new genus and species, Oreadomyia albertae, is described from the mountains of western Alberta. This differs in several important adult characters from the three previously known genera and species of Nymphomyiidae, particularly in the possession of mouthparts (which are rather unlike those of other Diptera), in the form of the compound eyes, and in the virtually apterous condition. It is placed in a new subfamily, Oreadomyiinae. Further records of Palaeodipteron walkeri Ide are given for New Brunswick. These include examples of the previously unknown, fully alate adults. The systematic position of the Nymphomyioidea is briefly discussed. The group is retained in a separate suborder, Archaeodiptera. An appendix gives a list of arthropods trapped at the same site as O. albertae.

White Spruce

An approach, involving all of the agencies that might be involved in a spray permit approval, to the design of a chemical control program for a zeiraphera sp. infestation in extensive white spruce plantations in New Brunswick is described. The issues and constraints encountered in the exercise and that would probably be common to any attempt at implementing chemical control of a pest in plantations are highlighted. Steps that must be taken to resolve some of these difficulties are discussed. Adaptive Environmental Assessment and Management is suggested as an approach that might resolve issues and contraints.

AbstractMitosynum vockerothi, a new genus and new species of Staphylinidae, is described from Kouchibouguac National Park, New Brunswick. The genus is compared with the genus Syntomium Curtis (Oxytelinae: Coprophilini). The phylogenetic position of the genus is considered based on Herman's (1970) study of the phylogeny of the genera of the Oxytelinae.
