Effect of horticultural oil on oviposition behaviour and egg survival in the obliquebanded leafroller (Lepidoptera: Tortricidae)
Download2009
Evenden, M. L., Wins-Purdy, A. H., Whitehouse, C., Judd, G. J. R.
Abstract: The effects of the horticultural oil Purespray Green on oviposition behaviour and egg development in the obliquebanded leafroller, Choristoneura rosaceana (Harris), were investigated through dual-choice and no-choice bioassays and topical applications of oil to developing eggs. A...

Effect of humidity and nutrient content on the survival of Staphylococcus aureus on a glass surface
Download2013-03-13
Surfaces contaminated with Staphylococcus aureus can play an important role in its transmission throughout communities and hospitals. Previous research on S. aureus surface survivability has generally used high density inocula (>105 CFU mL-1), which may lead to cryptic growth of the cells, as...

Light (about 3,000 foot-candles) neither increased nor decreased the sink strength of young, rapidly expanding leaves of Phaseolus vulgaris L. cv. Black Valentine, as measured by the comparative rates of import of 14C-labeled photosynthates by sink leaves in the light versus dark in short term...

Effect of melanism of alpine Colias nastes butterflies (Lepidoptera: Pieridae) on activity and predation
Download2006
Abstract: Melanism in the Sulphur butterfly Colias nastes Boisduval was quantified and related to their ability to remain active under cool or cloudy conditions and to their risk of predation. Darker individuals were more active, moved greater distances, and disappeared from the population at a...

Effect of Pairing Status on Use of Space by Territorial Willow Ptarmigan (Lagopus lagopus): Bachelor Males Choose Life on the Edge
Download2003
Hannon, Susan, J., Eason, Perri K.
One function of territorial defense may be to facilitate mate guarding by resident males. To assess the importance of mate guarding in territoriality, we examined the spatial pattern of intrusions by male Willow Ptarmigan(Lagopusla gopus) on the territories of other males and we compared use of...

Effect of Plant Age, Larval Age, and Fertilizer Treatment on Resistance of a cry1Ab-Transformed Aromatic Rice to Lepidopterous Stem Borers and Foliage Feeders
Download2000
Rubia, L., Ghareyazie, B., Alinia, F., Bennett, J., Cohen, M. B.
Abstract: The resistance of vegetative, booting, and flowering stage plants of a variety of an aromatic rice, Oryza sativa L., transformed with a Bacillus thuringiensis Berliner cry1Ab gene under control of the maize phosphoenolpyruvate carboxylase (PEPC) promoter was evaluated against four...

Effect of Pollination Success on Floral Longevity in the Orchid Calypso bulbosa (Orchidaceae)
Download1995
The lifespan of an individual flower is often affected by pollination success. Species differ regarding whether male function (pollen removal), female function (pollen deposition), or both trigger floral senescence. We studied senescence in the single- flowered, deceptive orchid Calypso bulbosa...

Effect of water stress and plant defense stimulation on monoterpene emission from a historical and a new pine host of the mountain pine beetle
Download2011-01-01
Cooke, Janice E. K., Blanchet, F. Guillaume, Lusebrink, Inka, Erbilgin, Nadir, Evenden, Maya L.
The mountain pine beetle (Dendroctonus ponderosae, MPB) has killed millions of lodgepole pine (Pinus contorta) trees in Western Canada and recent range expansion has resulted in attack of jack pine (Pinus banksiana) in Alberta. Establishment of MPB in the Boreal forest will require use of jack...
