Forshaga had it's 1st mosquito treatment
After our team observed flooding and hatching last week. This week, after a thorough inspection throughout the area, we conducted our first control treatment in the area. On Tuesday, July 14th 154 hectares were treated by helicopter. Through physical and digital follow up we see that the treatments were successful. There remains some risk of hatching in areas where we do not have permission from landowners but otherwise, local residents should not be negatively impacted by the floodwater mosquitoes.
Gävle Municipality has challenged the decision by the Swedish Environmental Protection Agency
An appeal by Gävle municipality to the Swedish Environmental Protection Agency has now been submitted to the courts for land and the environment. The municipality is challenging a part of the decision that denies treatments in the three Natura 2000 areas; Jordbärsmuren-Ålbo, Tjursöarkipelagen and Spjutholmen.
The current mosquito situation
As expected in the spring, mosquitoes begin to show themselves. These early season mosquitoes are those that overwinter as adult females. The large mosquitoes with striped legs and spotted wings can be a nuisance but only for a short period. We have also conducted field visits in both Nedre Dalälven and Klarälven and they both show low water levels with relatively dry floodplains. In some concentrated areas in Forshaga we did find snowpool mosquito larvae and pupae which will likely be in the air in 1-2 weeks. This species is not among the mosquitoes we seek to mitigate.
The target group for mitigation are floodplain mosquitoes which have laid their eggs and await a proper flood event. We continue to keep our focus on these conditions along the Dalälven and Klarälven.
The Environmental Protection Agency has made their decision!
On March 26, the Swedish Environmental Protection Agency granted an exemption which will allow us to conduct mosquito control along the Nedre Dalälven for the years 2020-2022. As in previous years we did not receive teh exemption for Natura 2000 areas Sputholmen, Tjursö archipelago, and Jordbärsmuren-Ålbo. The full decision along with appendices can found at this link to the Environmental Protection Agency's website (Swedish only).
Concurrently, Forshaga mosquito control also received an exemption but for the year 2020 (as applied for). All areas aside from the Natura 2000 area, Näs were approved. This decision can be found at this link to the Environmental Protection Agency's website (Swedish only).
The Nedre Dalälven application process is at the stage where the Swedish Environmental Protection Agency has now forwarded our request on to the central government (read here, Swedish only). Regarding Forshaga, our opinion on the stakeholder response to our application has been submitted to the Swedish EPA (read here, Swedish only). Following their review, we expect that our request for mosquito control with Forshaga will also be forwarded on to the central government.
Decision on mosquito control for 2019
On April 26th the Swedish Environmental Protection Agency approved mosquito control along the Nedre Dalälven.
We are now working in Forshaga Municipality as well!
For 2019 we have the assignment of preparing for treatments of floodplain mosquitos along the Klarälven in 2020. This includes collecting mosquito abundance data in the affected area. You can find more information in the menu under Forshaga or by clicking here.
We 're now looking for a mosquito control technician with start from February 2019.
Article about the mosquito fauna of Nedre Dalälven
We have a new publication in the Journal of the European Mosquito Control Association. You can read our article "The Nedre Dalälven River Landscape in Central Sweden - a hot-spot for mosquito (Diptera: Culicidae) diversity" here.
Mosquito control season is over
Our permit to control mosquitoes ended on August 31, so the mosquito control season 2018 is over now. We have already started with the preparations for next year's mosquito control. Do you want to know what we do all year round - look at "our year" here.
