The BG-Counter is an electronic device that counts mosqui-
toes as they fly through and wirelessly transmits the data to
a cloud server. Differentiation of mosquitoes from smaller or
larger insects, and from other objects such as dust or rain
particles, is based on size and wing beat. Mosquitoes, small
Diptera such as chironomid midges and fungus gnats, and
other insects with a similar size cannot be reliably differen
-
tiated. Therefore, to improve classification accuracy, the BG-
Counter utilizes carbon dioxide (CO
2
) to attract only blood
sucking insects. By using CO
2
as an attractant the accuracy
of correctly counted mosquitoes is in the range of 80-90 %.
Accuracy may vary from location to location and should be
verified from time to time (see accuracy of counts).
Description of the BG-Counter
We recommended to use the BG-Counter in combination
with a BG-Trap Station (with parts of the BG-Pro with a spe-
cial 12 V fan) or a BG-Sentinel trap that remove the insects
after they are sucked through to avoid multiple counts of the
same insect. To ensure accurate counts, the trap must not
allow collected mosquitoes to escape.
Equipped with basic sensors, the BG-Counter also samples
local environmental data such as temperature, humidity
and light. The system is supported by a web application for
storage of mosquito counts as well as geospatial and envi-
ronmental data. Via this web application you can remotely
switch the trap and the BG-Counter on and off. It also allows
you to set up varying time schedules to run the trap and con-
trol the application times of CO
2
.
The BG-Counter needs mobile reception to transmit data to
the web server. Therefore, place the BG-Counter with the
trap only in areas with mobile reception. You can check the
local reception with your mobile phone.

The BG-Counter will automatically select the mobile provi-
der that is available at the chosen location.
