In February 1976, first instar nymphs of a mealybug were found overwintering in bark crevices of cherry trees at Penticton, B.C. As these were much smaller than and distinctive from overwintering second and third instar nymphs of the apple mealybug, Phenacoccus aceris Signoret, which were present in large numbers, they were collected and reared to the adult stage on small cherry trees in a greenhouse. Mature fernales were identified by Dr. W. R. Richards, Biosystematics Research Institute, Ottawa as the Comstock mealybug, Pseudococcus comstocki (Kuwana).

Methods Of Control

A leafroller, Dasystoma salicellum Hbn. (Lepidoptera:Oecophoridae), recorded on this continent only from Lulu Island, B.C., in 1955, became a pest m 1962 when the larvae were found infesting the early berries, and mechanical pickers dislodged large numbers into the crates. This univoltine, phytophagous, photopositive insect overwinters as the pupa in the litter under the bushes. Flightless females emerge in mid-March, mate, and lay eggs under the blossom scales and loose bark of the canes. The eggs hatch in 2 weeks beginning in mid-May and the larvae destroy flower buds, invade or scar the berries, and sometimes defoliate the bushes.Preblossom sprays were not effective because plots were reinfested by first-instar larvae blown in from wild hosts nearby. Single postblossom sprays of phosphamidon, TDE, mevinphos, malathion, carbaryl, and Perthane and three sprays of Thuricide (Bacillus thuringiensis Berliner) were all effective. Malathion is recommended. Several non-chemical methods of control are discussed.

A New Species

Lampetra macrostoma n.sp., a freshwater parasitic lamprey, is distinguished from related species L. tridentata, L. lethophaga, L. folletti, L. minima, and L. similis by its parasitic habit and very large disc. Other characters distinguishing the species from L. tridentata are its longer prebranchial length, large eye, weakly pigmented velar tentacles, and its ability to remain in freshwater. The recently metamorphosed form readily survives in freshwater and probably is non-anadromous even though it can survive in salt water. The new species has been discovered in two lakes on Vancouver Island, British Columbia, Canada, where it attacks large numbers of resident salmonids. Because of its ability to survive and feed in freshwater, it poses a definite threat to freshwater fishes.Key words: lamprey, new species, non-anadromous lamprey, salmonid parasitism

This checklist of the oribatid fauna of Canada and Alaska (excluding Astigmata) includes 580 identified species in 249 genera and 96 families. The known fauna of Canada includes 556 identified species in 247 genera, and that of Alaska includes 182 species in 95 genera; 39 of the 42 oribatid superfamilies are represented. We further list ~ 300 species that are currently unidentified, and possibly undescribed. In addition, we list 42 genera that are represented only by unidentified and probably undescribed species. For each species we give combinations and synonymies, specific locations in Alaska and the Provinces and Territories of Canada, habitats, and biogeography.                There are 182 identified species known for Alaska, 152 for Yukon, 122 for Northwest Territories, 58 for Nunavut; 210 for British Columbia, 213 for Alberta, 15 for Saskatchewan, 84 for Manitoba, 167 for Ontario, 210 for Québec, 110 for Nova Scotia, 77 for New Brunswick, 84 for Newfoundland and 6 for Prince Edward Island. The known fauna of Canada is smaller than that of Austria, and is approximately equivalent to that of the Czech Republic. As these countries are much smaller in size than Canada and less ecologically diverse, we consider the Canadian and Alaskan fauna are at most 25% known. The paucity of these data reflects the absence of taxonomic and faunistic studies on Oribatida in State, Provinces or Territories, and especially in the Canadian and Alaskan National Park systems and the hundreds of Provincial Parks.                Despite the almost 90% increase in described species since the catalogue of Marshall et al. (1987), there is a need for focussed, coordinated research on Oribatida in the natural regions throughout Canada and Alaska, and for monographs on families and genera with large numbers of undescribed species, such as Brachychthoniidae, Damaeidae, Cepheidae, Liacaridae, Oppiidae, Suctobelbidae, Hydrozetidae, Phenopelopidae, Scheloribatidae, Haplozetidae and Galumnidae. 

PHYTOSTEROL REQUIREMENT FOR PROPAGATION OF RHINOCYLLUS CONICUS (COLEOPTERA: CURCULIONIDAE) ON ARTIFICIAL DIETS

Rhinocyllus Conicus

The development of Rhinocyllus conicus Froelich was evaluated on 52 artificial diets. Selected diet constituents were varied to determine their effects on weevil development. High mortality without initial feeding on diets with cholesterol suggested that phytosterol is essential as a phagostimulant. Only nine of the diets supported development of first instar larvae to the adult stage; sitosterol was present in each of the successful diets. The low yields of adult weevils indicate inadequacies in the diets.

During a study of the parasites attacking the forest tent caterpillar, Malacosoma disstria Hbn., a ready means of identifying puparia of the common dipterous parasites proved necessary so that those individuals that failed to develop beyond the puparial stage in laboratory rearings might be identified in advance of lengthy cold treatment and incubation. The following key was therefore developed on the basis of the study of series of puparia associated with adults determined by the Entomology Research Institute. The key includes the ten most common dipterous parasites of the tent caterpillar in Ontario, seven of which have been included in a similar key to the parasites of Malacosoma spp. in British Columbia (Ross 1953). The terminology used in these two keys is similar, and is adapted from Green (1921).

Croesia holmiana (L.) was the most common of nine species of tortricids found in 1977 in a survey of the apple leafrollers of the Vancouver, British Columbia, district. It is an European species not recorded previously from North America. Specimens from British Columbia were identified by Dr. A. Mutuura, Biosystematics Research Institute, Canada Agriculture, Ottawa.

Some time ago I published data on orthopteroid insects from northern Canada and Alaska (Vickery 1967, 1969). Two species and one subspecies were described as new. Two of these taxa occur only in the Yukon and Northwest Territories.Since that time additional information has become available. During 1982 two lots of northern orthopteroid insects were received for identification. These were sent from the Spencer Museum, University of British Columbia and from Biosystematics Research Institute, Canada Agriculture, Ottawa. These are abbreviated in the following list as UBC and CNC, respectively. The UBC specimens were collected by S. G. Cannings, R. J. Cannings, C. S. Guppy, B. Gill, and G. G. E. Scudder mainly in 1980 and 1981. The CNC specimens were collected in 1981 by C. D. Dondale.
