Biogents – Science for Your Protection –

The BG-Pro: All Your Needs in One Product

The BG-Pro is a new modular trap for professionals and is ideal to collect all types of mosquitoes. It was developed to offer the functions of the most widely used monitoring traps in one product while providing Biogents patented technology, production quality, and design expertise:

  • higher quality parts
  • less energy consumption
  • overall better performance
  • comparable price

Different styles such as EVS-style, CDC-style, or Sentinel-style can be easily changed into each other.  Furthermore, the modularity enables you to be flexible in your monitoring programs and optimize your BG-Pro to your local and temporal monitoring needs. You have several options and the BG-Pro even offers room for your creativity.

Multiple designs in one product

  • Changed different styles easily into each other:
    • EVS-style
    • CDC-style
    • Sentinel-style
  • Perfect for all habitats and mosquito species
  • Hanging or standing choice

Designed for use with Biogents attractants, CO2, and light

Biogents attractants: Used with BG-Lure and placed on the bottom, the trap can monitor tiger mosquitoes (Aedes albopictus and Aedes aegypti).

CO2: Used with CO2, it captures all mosquito species.

LED: An LED light can optionally be added.

Low power consumption for longer battery life. Fan can run on 5 or 6 V

Reduced consumption of electricity – the 3 blade ventilator consumes less power and thus increases battery life.

High Quality Fan

  • Very robust, high-quality fan: The fan is so robust that it can even be operated for hours and days in salt water.
  • The fan can run on 5 or 6 V
  • Fan with only 3 blades: If mosquitoes are sucked through the fan, they are less damaged and can be easier identified.

Multiple power options (battery, mains power supply, power bank)

  • The trap can be run on a 6 V (normal suction power). You can also run the BG-Pro with a 12 V battery (extremely strong suction power) but then the UV light should not be used. Battery cables included.
  • Additional USB adapter included: with the new USB adapter, commercially available and light-weight power banks (5 V)can be used as power supplies. The power bank can be stowed in a slot on the bottom of the trap body.
  • Power supply (8 m) and extension cords (10 m) are additionally available to run the trap from the mains power supply.

Catch bag above the fan reduces mosquito damage

  • The catch bag is located above the fan so mosquitoes do not pass through the fan. Therefore, the mosquitoes are less damaged and species are easier identified.
  • For trapping extreme large numbers of mosquitoes, the catch bag can be removed and mosquitoes are sucked through the ventilator. The whole trap body serves now as the catch bag.
The catch bag of the BG-Pro can be located above the fan so that mosquitoes do not pass through the fan.   
  • An automatic shutter ensures catch integrity in every situation

Dual-Use Packaging

  • The carrying bag has a dual purpose and can be used as the dry ice container
  • The trap parts fit into each other and are placed compactly into a small bag for transport. Easy to set up, to handle, and to transport.

Biogents Attractants

Improve the traps‘ performance with Biogents attractants, the patented human scent mimics, to increase catch rates for Aedes albopictus and Aedes aegypti (for those species, the traps should be placed on/near the bottom):

  • BG-Lure: 5-month lure
  • BG-Sweetscent: 2-month lure

The attractants can be ordered via our webshop for researchers >
When the Biogents attractants are used in conjunction with CO2, the synergistic effect can multiply the catch rates.

CO2 Upgrade

The BG-Pro can be upgraded with CO2 to catch all mosquito species including the malaria mosquito Anopheles and to increase catch rates.
There are several possibilities to upgrade the trap with CO2 (click on each line to get more information):

Dry ice

On the right hand, an example for the EVS-style version: The CO2 is stored in the Biogents bag above the trap. Additionally, a power bank can be stored in the bag.

CO2 gas bottle

Biogents offers a CO2 upgrade set (BG-Booster CO2) including pressure regulator for CO2 gas bottles. The BG-Booster CO2 can be ordered via our webshop for researchers >

Yeast fermentation with our new BG-CO2 Generator!

Scientific studies on the BG-Pro

Images of publications

The BG-Pro can do everything the BG-Sentinel does, and has several other advantages (Degener et al., 2021):

  1. In comparison to the BG-Sentinel, the BG-Pro yields, in most cases, equivalent, or superior catch rates of Ae. aegypti, Ae. albopictus, Ae. polynesiensis, or Culex spp.
  2. The BG-Pro uses 35% less power than the CDC and 75% less than the BG-Sentinel, and can therefore run at 5 V for 2 days using a small lightweight 10,000-mAh rechargeable power bank.
  3. The BG-Pro is a modular trap that can be used in at least three different configurations (by adding or removing certain accesories): BG-Sentinel style, CDC style, and EVS style.
  4. When configured as CDC style and EVS style, and compared to CDC and EVS traps, the BG-Pro reached either equivalent or similar catch rates for Ae. vexans, Cx. pipiens, Cx. erraticus, and Cs. melanura.
  5. The BG-Pro is made of higher quality parts, but is slightly cheaper, than the BG-Sentinel.

The BG-Pro has already been used in several studies with different objectives and excellent results:

  • Brazil – Ellwanger et al. 2022: BG-Pro used in BG-Sentinel style and EVS style, both baited with CO2 from dry ice and BG-Mozzibait.
    • Mosquitoes from at least 50 species and 14 genera were collected
    • Two first descriptions for the State Rio Grande do Sul: Mansonia pessoai and Toxorhynchites theobaldi
  • Netherlands – Agliani et al. 2023: BG-Pro baited with CO2 from molasses fermentation.
    • 96 Mosquito pools of Cx. torrentium/ Cx. pipiens were tested for USUV and Plasmodium infections. 18 pools were positive for Plasmodium spp
  • Thailand – Chaiphongpachara et al. 2022: BG-Pro in CDC style (hanging, baited with CO2 and BG-Lure).
    • Anopheles females belonging to eight species collected: An. baimaii, An. minimus s.s., An. epiroticus, An. jamesii, An. maculatus s.s., An. barbirostris , An. sawadwongporni, and An. aconitus.
  • Thailand – Chaiphongpachara et al. 2022: BG-Pro in CDC style, baited with CO2 and BG-Lure, and larval dipping for mosquito survey.
    • Mosquitoes from 65 species were collected with BG-Pro traps from several provinces (table S1)
  • Thailand – Saiwichai et al. 2023: BG-Pro in CDC style, with CO2 and BG-Lure
    • Survey of Japanese Encephalitis vectors Cx. pseudovishnui, Cx. tritaeniorhynchus, and Cx. vishnui and posterior geometric morphometrics and DNA barcoding, as the three species have very similar morphology.
