BG-Counter 2: a remote monitoring device for mosquitoes

The BG-Counter 2 offers remote monitoring with automated mosquito counting from anywhere in the world at any time. The innovative smart device is placed on top of a Biogents mosquito trap. It differentiates mosquitoes from other insects, counts them, and wirelessly transmits the results to a cloud server. With the BG-Counter App, you can manage your traps and analyze your data.

Optimize with the BG-Counter the effectiveness of your control activities and therefore save money! Additionally, remote monitoring saves time and manpower, and is thus also more economical.

• Better treatment timing
• More effective treatment
• Better control for less money

• Automatic mosquito counting
• Trap management from the office
• Comprehensive analysis

The BG-Counter enables real-time measurements as well as historical analysis of infested areas. Vector control professionals can now establish surveillance programs with unprecedented accuracy and temporal resolution of data, overcoming labour constraints associated with manual inspection.

Automatic mosquito counting

The BG-Counter reports mosquito counts and environmental data remotely to the BG-Counter App, where the data are available in real-time.

Detailed insights into activity patterns

The BG-Counter reports mosquito counts every 15 minutes. This high density of data gives you unprecedented insights into mosquito activity patterns.

Cost saving

Very little fieldwork time is required, to have a BG-Counter operating that send you data every 15 minutes, 24/7. One of our customers estimated 3h of field work per trap for a trapping period of 1 month. This save you a lot of manpower!

Optimizing your control activities also reduces costs.

Features in Detail

  • The BG-Counter 2 counts mosquitoes while they are sucked into a Biogents trap and differentiates them from other insects or dust particles.
  • Mosquito counts with an accuracy of 90% have been established in field tests when working with CO2 as an attractant.
  • Up to 5 mosquitoes per second can be recorded.
  • Sampling of local environmental data: temperature, humidity and ambient light.
  • The effectiveness of control measures can be validated immediately.
  • The BG-Counter 2 minimizes maintenance effort: it can run on solar power and is self-sustaining. It is robust and well protected against weather.

The BG-Counter includes

  • 1x mobile module
  • 1x SIM card for data transmission
  • 1x fan adapter cable
  • 1x battery cable
  • 1x mains supply
  • 1x CO2 pressure reducing regulator with output pressure of 2 bars
  • 1x CO2 tube
  • 1x BG-Pro Counter version (1x funnel net, 2x catch bag, 1x inner cylinder with upper part and lower part with 12V fan, 1x trap body, 1x carrying bag, 1x tripod)

Technical Details

The patented insect sensor consists of arrays of infrared LEDs and light detectors that provide reliable and sensitive detection and differentiation of moquitoes from other objects entering the trap.

The heart of the BG-Counter 2 is a highly integrated printed circuit board which incorporates:

  • An infrared sensor
  • environmental sensors for temperature, relative humidity and ambient light
  • a cellular module for communication with the web server
  • an SD card for onboard data storage, fan and CO2 valve control
  • two powerful microprocessors for control and communication

BG-Trap Station

Biogents‘ BG-Trap Station is a robust and ideal shelter for your BG-Counter 2.

The BG-Trap station

  • is made of stainless steel
  • protects your BG-Counter 2 from environmental conditions
  • can be attached to any type of terrain
The BG-Counter ideally works together with the BG-Trap Station.

Solar Power

You can run the BG-Counter 2 on solar power. In this way, remote monitoring get’s even easier!

In the video below, Catherine Pruszynski from the Floria Keys Mosquito Control District shows how to set up the BG-Counter 2 with a solar panel.

BG-Counter App

The BG-Counter app is a vital part of the BG-Counter 2. The Counter sends data from the field (mosquito counts, environmental data, geospatial data) to the web-based BG-Counter App. The data base is automatically updated with the data constantly generated in the field.

In the BG-Counter App, you can:

  • Manage your traps
  • Set up time schedules for traps and CO2
  • Comprehensively analyze your data

Comprehensive Data Analysis:

  • Analysis of mosquito activity patterns can be performed for different time ranges, and with different temporal resolutions (15 mins, daily, weekly, monthly).
  • Mosquito hotspots can be identified with the help of infestation maps.
  • The activity of day and night-active mosquitoes can be visualized separately.
  • It is possible to directly compare multiple locations, and to perform group-based analyses.
  • The data can be exported to Excel.

The BG-Counter 2 comes with a CO2 pressure regulator and we strongly recommend to use the BG-Counter with CO2!

Adding carbon dioxide

  • highly increases the overall mosquito catch rate
  • highly increases the trap’s specificity for mosquitoes (and other hematophagous insects)
  • makes the trap highly attractive for all mosquito species

Tipps for saving CO2:

  • In order to save CO2, you can define time periods in which CO2 is being released, after you have established the daily activity pattern of your local target mosquito species.
  • If you want to keep a close eye on the day-and night active mosquitoes around the clock, you might as well choose a schedule of 30 min CO2/ 30 min CO2 off or similar.

It is however important that you keep in mind, that your BG-Counter will only collect reliable data with CO2.
