Non-GMO approach reduces cases of mosquito-borne dengue by 77%   (GM Watch, 31 August 2020)     'While uncertain and risky GMO approaches to mosquito-borne diseases continue to raise concerns in the countries targeted for experimentation, like Brazil, Burkina Faso, and most recently the United States, two remarkable breakthroughs have recently been made involving highly effective natural means of preventing the transmission of such diseases. In the most recent instance, a randomized field trial found that mosquitoes infected with a natural bacterium called Wolbachia reduced cases of dengue by an "extraordinary" 77%. Wolbachia stops the insects from transmitting some viruses when they bite people'.

The Way Humans Alter the Environment Increases the Prevalence of Disease Carrying Mosquitoes   (Beyond Pesticides, September 16, 2020) Disease carrying mosquitoes are more likely to flourish in areas being altered by human activities, according to new research published by scientists at Oregon State University.   Human disturbance was measured by five factors, including (i) pesticide use, (ii) nutrient loading, (iii) human population density, (iv) biomass of grazing animals, and (v) loss of vegetation.   While these factors are all well known hazards for wildlife, researchers determined that disease vector mosquitoes are one important exception. Unsurprisingly, each of these impacts are significantly higher, by orders of magnitude, outside the park than inside. It followed that mosquito abundance outside the part is determined to be an average 2.9 times (ranging between 1.5 and 10 times) greater than paired sites of similar layout inside the national park.   Sheer numbers are merely half the story. Scientists also observed changes in the relative abundance of certain species of mosquitoes. Disease carrying mosquitoe populations are much higher outside of the park than inside, consistently accounting for roughly 80% of the difference in community composition between paired sites.   A sound approach to mosquito management is science-based and prioritizes preventive measures.

Blackberry Leaves Decompose to Thwart Mosquito Breeding  (Beyond Pesticides, December 21, 2019)  Adding blackberry leaf litter in stormwater catch basins creates an “ecological trap,” enticing mosquito females to lay eggs in sites unsuitable for larvae survival. 

WATCH – A Question of consent: Exterminator Mosquitoes in Burkina Faso. (Global Justice Ecology Project, December 20, 2018)   'The (15 minutes - a lot in French with English subtitles) film, “A Question of Consent: Exterminator Mosquitoes in Burkina Faso” documents conversations with residents of the areas where Target Malaria is conducting tests, as well as opposition from civil society groups in the region. This is not the first time Burkina Faso is experimenting with GMOs: Monsanto introduced genetically modified BT cotton into the country in 2008, which led to a drop in the quality of cotton.'   SNAP Comment: Large scale fogging with insecticides has been a failure over and over again for mosquito control and the gmo mosquito experiment on Grand Cayman Island was suspended. Detail: Several decades ago the Regina Public Library had a few scientific compendiums of research on the successes and faillures of pesticides in controlling pests. On a world scale study of malaria and other diseases control and with thousands of papers referenced), the efforts had been a failure. After plastering the world with DDT and other long lasting organochlorines and then moving on to other classes of insecticides like carbamates and organophosphates, the only place in the world where these efforts led to a disappearance of mosquitoes was on a tiny island in the Mediterranean. This only occurred for a few years until new mosquitoes found their way in and they were back to square one. What they found instead is that resistance appeared in only a few years and the quantity of insecticide used had to be increased constantly to keep ahead, until they tried a new product and the same thing quickly happened. There is a term for that: the pesticide treadmill. Of course there were no concurrent efforts to identify and manage the mosquito habitat or educate people on mosquito management. These gmo mosquitoes have also been released on Grand Cayman Island and the program is now being suspended with questions on its efficacy. However, now we think we can have better success on a huge continent??? Imagine how many species of mosquitoes there are, and that many species can often be carriers of the same disease and that you would need to bioengineer every species in an attempt to control it. If you only control one another species will likely become dominant and so on. As far as I am concerned, this type of intervention is madness and the money should be redirected.

Edmonton's Mosquito Control 2016  This map is based on City of Edmonton logs of the chemicals applied specifically to control mosquitoes in 2016. Click on each data point for details. Each point represents the center of a 1-mile square corresponding to a grid point from city data. The actual application(s) could be anywhere within the surrounding one mile square - this could be up to 1.2 kilometers on a diagonal line. The City does not track applications more precisely than to identify the grid ID. The comments indicate whether the application was Ground or Air. Additional comments are verbatim from City data. The data is presented in layers based on the product used. You can select or de-select layers as you wish to tailor your view. SNAPComment: I believe Edmonton is the last Canadian city to still use the organophosphate chlorpyrifos for mosquito control.Chlorpyrifos has been banned for consumer use because of its toxicity.  more on chlorpyrifos
