The bagworm family (Lepidoptera: Psychidae) includes approximately 1000 species, all of which complete larval development within a self-enclosing bag. The family is remarkable in that female aptery occurs in over half of the known species and within 9 of the 10 currently recognized subfamilies. In the more derived subfamilies, several life-history traits(More)
BACKGROUND Recognizing the importance of increased patient participation in healthcare decisions leads decision makers to consider effective ways to incorporate patient perspectives in Health Technology Assessment (HTA) processes. The implementation of local health HTA units in university hospitals in Quebec provides a unique opportunity to foster an(More)
BACKGROUND Geographic range limits and the factors structuring them are of great interest to biologists, in part because of concerns about how global change may shift range boundaries. However, scientists lack strong mechanistic understanding of the factors that set geographic range limits in empirical systems, especially in animals. METHODOLOGY/PRINCIPAL(More)
The present study evaluated an oviposition threshold for flight in a moth species with an unusual inter-reproductive migration strategy, the spruce budworm (SBW), Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae). Females typically lay some eggs in their natal patch then ascend by flight above the plant canopy to the atmospheric boundary layer(More)
BACKGROUND Public and patient involvement in the different stages of the health technology assessment (HTA) process is increasingly encouraged. The selection of topics for assessment, which includes identifying and prioritizing HTA questions, is a constant challenge for HTA agencies because the number of technologies requiring an assessment exceeds the(More)
BACKGROUND The literature recognizes a need for greater patient involvement in health technology assessment (HTA), but few studies have been reported, especially at the local level. Following the decentralisation of HTA in Quebec, Canada, the last few years have seen the creation of HTA units in many Quebec university hospital centres. These units represent(More)
Wing wear of adult butterflies has been used to record age-related demographic parameters in hundreds of studies, but this technique has surprisingly been rarely used in moths and never in the context of pest management. A method for scoring wing wear of eastern spruce budworm, Choristoneura fumiferana (Clemens), the most severe pest in eastern North(More)
Adult spruce budworms, Choristoneura fumiferana Clemens (Lepidoptera: Tortricidae), were captured at light traps in New Brunswick (NB) in 2012, Québec (QC) in 2013, and Newfoundland (NL) in 2014; population densities were low in NB–NL, and moderate in QC. Morphological parameters (wing score index, wing length, dry weight, residual fecundity) were estimated(More)
We report data collected over the entire course of an outbreak of jack pine budworm, Choristoneura pinus pinus Freeman (Lepidoptera: Tortricidae), between 1984 and 1988 at 12 plots in Manitoba. The positive relationship between the level of defoliation, used as a proxy for population density, and the abundance of eggs suggests local reproduction by females.(More)
Carbon monoxide, a gas originating from incomplete combustion of carbon-based fuels, is an important cause of human deaths. In this paper, we describe an unusual carbon monoxide poisoning in a dwelling without obvious sources of combustion gases, for which two adults had to be treated in a hyperbaric chamber. Carbon monoxide readings were taken in the house(More)
