[EN] BIOLOGISK MYGGKONTROLL

Vi utvecklar metoder för miljömässigt balaserad kontroll av myggproblem

The aim of Biological Mosquito Control is

to reduce the abundance of floodwater mosquitoes to acceptable levels so that people can enjoy living in and visiting the Nedre Dalälven region.

The appeal will not adversely effect this year's mosquito control

In lieu of the appeal against areas excluded from mosquito control, there was some uncertainty as to whether our permits would be delayed in the areas in which the Swedish Environmental Protection Agency had granted permission. Therefore, NEDAB had submitted to the Land and Environmental Court a request to honor the permits while deliberating on the particular areas in question. The Land and Environmental Court decided that the Swedish Environmental Protection Agency's decision shall apply immediately in those parts that have not been appealed. Thus, there is no obstacle to fight in the areas with permission if necessary.

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).

Update on the Application Process

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. Read more

UPCOMING

Week 21

Preparations for the possibility of mosquito control, ongoing servicing of our non-target organism traps and our monitoring program are in progress.


Week 22

We will continue to monitor conditions in both Nedre Dalälven and Klarälven.  Simultaneously, the non-target organism program continues on it's weekly schedule.


Week 23

Alongside the regular, weekly maintenance of our non-target organism program, our monitoring program follows this bi-weekly schedule.

​Mosquitoes

There are around 50 species of mosquitoes in Sweden and we have found 33 species in the area around River Dalälven.

Mosquito control

Larvae of floodwater mosquitoes are controlled by aerial application of VectoBac G granules, which contain Bti as active ingredient and are dispersed by helicopter.

Non-target programme

To study the potential environmental impact of Bti, we have a non-target organism  programme.
