Removal of the Mosquitoes
Identification is complicated if the insects stay in the trap for
more than a week and dry out or if they get wet.
Removal of the mosquitoes:
Remove the funnel.
For direct sorting / identification in the field: Loosen the
catch bag and remove it from the transparent chamber. Mos-
quitoes can then be removed with forceps or poured into a
white tray for sorting.
For returning the catch to the lab (e.g. for identification/
classification): Loosen the catch bag and remove it from the
transparent chamber. Then close the net by pulling the cord
of the catch bag tightly shut [F14]. It is best to put the catch
bag in a freezer for at least an hour to kill the mosquitoes.
Put a new catch bag over the open end of the transparent
chamber as described in F5 - F10.
Positioning
The black colour of the BG-GAT attracts mosquitoes from some distance. So, the trap needs to be placed where it is readily
visible, but protected from rain. Please do not hide the BG-GAT in the bushes!
Even though rainfall does not damage the trap, there are some negative effects of rain:
•
The mosquitoes can be damaged and difficult to identify.
•
Mosquitoes avoid rain and prefer sheltered positions. In sheltered positions the catch rate can therefore be higher.
If you don't find a naturally sheltered position for the trap, it would be best to position the trap under a roofed area, or a self
made shelter to keep it out of direct rainfall.

Maintenance
Change the water (hay infusion or water with other attrac-
tants) once a month.
Remove any debris that falls into the trap or deters the mos-
quitoes from entering the trap.
If using oil or surface spray, retreat the translucent chamber
monthly.
