Book Description
Mosquito control is a topic of interest both locally and globally. Problems created by mosquitoes are threefold and include the nuisance factor, disease transmission, and problems stemming from mosquito control efforts. For many years, Winnipeg citizens have debated the merits of the current local abatement program. To date, North America has not experienced the incidence of mosquito-borne-pathogens to the extent of other regions, though the arrival of West Nile virus in 1999 to the continent has increased the focus of scientists and the general public on mosquito control issues. Integrated pest Management (IPM) is the current method of choice for mosquito control. This thesis contains the results of research, initiated in January of 2001, to address some specific issues surrounding mosquito control in Winnipeg, Manitoba. The objectives of this thesis research were fourfold: a) gather and analyze information from Winnipeg residents regarding their knowledge of mosquitoes and their control; b) identify non-toxic mosquito control methods and test them for effectiveness and viabilty in an urban setting; c) create an annotated bibliography of mosquito educational tools appropriate for middle-years school children; d) based on the findings make recommendations for improvement to the Winnipeg IPM mosquito abatement program. The research was conducted through a literature review of key concepts, primary and secondary data review, semi-structured interviews, quantitative measurements and testing, participant feedback and participation. Data from Winnipeg residents were analyzed for themes and triangulated with literature review findings. Statistical evaluation was used to analyze non-toxic mosquito control product effectiveness. Recommendations for improvements to the Winnipeg program were formulated from information gathered from residents, product testing results, the annotated bibliography project outcomes, and from the literature review. Following a review of candidate mosquito control or repellent products, the Mosquito Magnet TM and Mosquito & Gnat Repellent were chosen for testing. Neither product was effective in reducing the number of mosquitoes collected in traps or the biting activity in the application area. There were correlations between the number of mosquitoes and environmental variables including; person effect, wind, temperature and cloud cover ...

Book Description
A survey was made on the control methods used by the Greater Winnipeg Mosquito Abatement District. It was found that a pre-season application of DDT gave much better results than spraying during the mosquito breeding season. Light trap catches over the past two years have shown that mosquito controls eliminated up to 90 percent of infestations in the area. Tests have indicated that the top minnow, Gambusia affinis, cannot overwinter in this climate. Tests have shown that no resistance to DDT has developed in the mosquitoes of the Winnipeg area. Mosquitoes were successfully tagged with rhodamine-B. Attempts were made to study flight range and habits. Attempts to establish a colony of prairie Aedes mosquitoes were unsuccessful. The limiting factor was the refusal of the mosquitoes to mate in captivity.
