Recent concerns about the spread of the mosquito-borne West Nile Virus (WNV) through North America
have prompted a number of regional studies of mosquito species composition and distribution. In this study, we report
on intensive surveys of mosquitoes on Prince Edward Island (PEI). Larvae ...

Provides an overview of insects and their close relatives. Coverage includes insect classification, behavior, ecology, genetics and evolution, physiology, and management, and references to relevant literature. All the major arthropod groups are addressed, along with many important families and speci...

Rev. of The caddisfly family Phryganeidae (Trichoptera) by G.B. Wiggins

The fishing (dock or wharf) spiders (Dolomedes spp. Latreille, 1804) of the Maritime Provinces of Canada were surveyed
through a combination of new collecting and examination of specimens from the Nova Scotia Museum and the New
Brunswick Museum. Four species (Dolomedes tenebrosus Hentz, 18...

High levels of azinphos-methyl (0.4–0.8 μg/L) were detected in the Wilmot River, Prince Edward Island, Canada, following runoff from an agricultural field after a heavy rainfall on 19 July 2002. Benthic macroinvertebrate abundance and diversity were sharply lower in samples collected 1 d after th...

Rev. of Ephemeroptera & Plecoptera : biology--ecology--systematics by P. Landolt and M. Sartori

The importance of microhabitat variables to stream macroinvertebrates can be difficult to assess due to the large number and intercorrelation of relevant environmental variables. In this study, substrate, detritus, and hydraulic variables were evaluated in patches arranged in a grid across a run of ...

In early July 1991, 234 pitcher plants (Sarracenia pulpurea) were transplanted from a Prince Edward Island bog being mined for peat into three bogs that varied with respect to previous pitcher plant abundance. One bog had a thriving natural pitcher plant population prior to transplant, while the oth...

Stonefly (Plecoptera) emergence was investigated between May and September of 1993 and 1994 in Catamaran Brook, New Brunswick, as part of a base-line study to evaluate the effects of timber harvest on Atlantic salmon habitat in Atlantic Canada. Thirty-one stonefly species representing seven families...

1. The life histories and population dynamics of the burrowing mayflies Hexagenia limbata and H. rigida were examined from 1986 to 1988 in four regions of an impounded lake in northern Manitoba, Canada. 2. Bottom temperatures reached 15-20-degrees-C, but ice-free periods of 4-6 months resulted in an...

Hexagenia limbata (Serville) and H. rigida McDunnough from Southern Indian Lake, Manitoba, were reared at 10-degrees, 15-degrees, and 20-degrees-C to assess temperature effects on growth. Subsequently, H. limbata was reared at two food levels and two or three nymphal densities (depending on size cla...
