Option 2
12 V battery (provided by user)
This is recommended if the counter is operated in a location for a few days,
before being serviced or moved. The minimum number of hours of operation
possible with a full battery can be calculated as follows:
Operation hours = Battery capacity (Ah) x 2.
For example, with a battery capacity of 60 Ah (Ampere hours), the counter and
fan can be operated for at least 60 x 2 = 120 hours = 5 full days.
Use “deep cycle” lead-acid, or lithium-ion batteries. Normal car batteries are not
designed for continuous charge/discharge cycling, and thus would have signifi
-
cantly reduced lifetime.
• Connect battery using battery cable
Option 3
Solar panel with solar battery
This is recommended when the system needs to be operated autonomously for extended periods of time.
While the trap/Counter are usually placed in a shady location, the solar panel should be placed in a sunny
spot nearby; the solar controller and battery should be placed near the counter.

Determination of Counting Accuracy
For routine operation, it is not recommended to use a catch
bag as the catch bag might be filled up too quickly. In this
way mosquitoes will be sucked through the ventilator and
end up dead at the bottom of the trap.
However, a catch bag can be installed when the BG-Counter
runs only for a few hours in order to check if the number
of counted mosquitoes by the BG-Counter corresponds
with the actual number of collected mosquitoes. In this way
the accuracy of the BG-Counter can be determined. When
comparing manual catch bag counts to electronic counts, it
should be noted that mosquitoes can “disappear” from the
catch bag:
Mosquitoes and other insects may be “stolen” by ants, spi-
ders, or geckos. For all calibration experiments make sure
that ants or other predators have no access to the catch bag.
You can protect the trap and catch bag by a water surface
around the trap, or by adding glue or PTFE to all trap parts
that might be accessible for predators.
If you make sure that mosquitoes do not leave the catch bag
after they have been sucked in the accuracy of the BG-Coun-
ter for correctly counted mosquitoes is between 80% and
90% correctly counted mosquitoes. If desired, experiments
can be performed from time to time to compare the catch
bag results with the electronic results reported for the same
time interval.
• Solar panel and solar controller are deliverd already connected [F16.1].
• Connect battery clamps to the battery (battery cables are delivered already con-
nected to the solar controller) [F16.2]. Pay attention to connect minus-pole to
minus-pole (black) and plus-pole to plus-pole (red).
• Connect the load cable to the BG-Counter [F16.3]
