Mosquito population surveillance activities allow us to
determine geographical distribution of species and to gather
specimen samples to test for West Nile virus. Foremost, our team of experts recommends larval sampling
of aquatic habitats with the help of ecological maps identifying
all possible breeding sites. This specific targeting is
accomplished using geomatic and photo-interpretation tools.
The adult surveillance period must extend throughout active
mosquito periods, from mid-May to end-October (or following
three consecutive night frosts). Uninterrupted monitoring
is ensured throughout this period with the help of a network
of fixed stations within the treatment area.
Identification and laboratory expertise

Our organisation guarantees identification and specimen
handling according to the most rigorous standards. Human
resources are equipped with a modern laboratory to identify
and preserve specimens.
Detection of West Nile Virus
An excellent tool for rapid detection
of West Nile virus had been made available. The "VecTest" detects
viral antigens (small proteins present on the virus)
in mosquitoes. Using fresh or dried mosquitoes not exposed
to high temperatures or reactive chemicals, 1 to 50 mosquitoes
can be tested at once. The procedure entails crushing
the mosquitoes in a solution which is then applied to
a test strip. The results are available within 15 minutes
and easy to interpret with the naked eye.
