| effects of release rates on the range of attraction of carbon dioxide to some southwestern ontario mosquito species. | the effects of release rates of 0, 250, 500, 1,000 and 4,000 ml/min on the range of attraction of carbon dioxide to some southwestern ontario mosquito species was determined using ramp traps placed at 3, 7, 11, 15 and 19 m from a central pressurized cylinder. for female aedes vexans, spring aedes spp. and anopheles walkeri, an increase in the release rate of co2 from 1,000 to 4,000 ml/min resulted in extension of the range of attractiveness from between 3-7 m to between 7-11 m; rates of 500 and ... | 1989 | 2565369 |
| attraction of culex pipiens/restuans (diptera: culicidae) mosquitoes to bird uropygial gland odors at two elevations in the niagara region of ontario. | in an effort to determine whether female culex pipiens l. and culex restuans theobald mosquitoes (diptera: culicidae) are attracted to crow, corvus brachyrhynchus, uropygial gland secretions, cdc miniature light traps (baited with co2 but with the lights removed) were placed at approximately 1.5- and 5-m elevations, in 10 trees in awoodlot near niagara falls, canada. these traps were assigned either a bird odor or a blank control. bird odors were created by attaching cotton swabs coated with cro ... | 2005 | 15962778 |
