BG-Sentinel: Features, applications and options

Different variations of External SiteBiogents' BG-Sentinel can be used according to the target species, the study aim and conditions in the field. The trap can be used with or without carbon dioxide, and with Biogents' proprietary human scent imitation for a anthropophilic mosquitoes (such as Aedes aegypti or Culex quinquefasciatus), the BG-Lure. We also offer a kit to add UV-light for biting midges (Ceratopogonidae) and other species that are attracted to ultraviolet light.

The BG-Sentinel needs a 12 V DC energy source. For a use on the electricity network, Biogents supplies mains adaptors. In the field, the traps can be hooked up to batteries. For normal field conditions, we suggest the use of motorcycle batteries which are readily available in most regions of the world. A capacity of 11 Ah is needed for every 24 hours (this includes a secruity factor).


When used in combination with Biogents proprietary artificial human scent, the BG-Lure, the BG-Sentinel is an excellent monitoring trap for yellow fever mosquitoes, their realtives from the genus Stegomyia, and other anthropophilic species. The BG-Lure releases an artificial skin odour (ammonia, lactic acid, and caproic acid) in a finely tuned ration similar to that of human skin. A version of the artificial scent which gives off smaller quanities of the active ingredients is called Sweetscent.
Due to a new formulation of our artificial scents we were able to significantly increase the effectiveness of our BG-Lure as well as of the Sweetscent. Download a flyer with more information about the new BG-Lure This is a pdf-file. and the Sweetscent This is a pdf-file..

Here is a video about the set-up and use of the BG-Sentinel trap for monitoring tiger mosquitoes in urban areas. See how you can monitor tiger mosquitoes in the most cost effective way:

Due to its form and design, the BG-Sentinel also permits the researcher to use highly diverse attractants, including live animals as lures or a number of other stimuli, thereby adjusting the capture spectrum precisely to specific needs of the study.

Adding carbon dioxide to the BG-Sentinel

When used in combination with carbon dioxide, the BG-Sentinel is an excellent monitoring trap for mosquitoes in general. The gas is released from an opening above the trap, thereby adding a smaller CO2 plume to the upwardly directed scent plume in the trap. This mimics the natural spatial distribution of the body scent and breath.

The trap receives a controled supply of carbon dioxide from a compressed gas cylinder: The pressure of the CO2 emission can be adjusted to the local and seasonal mosquito situation with the specialized pressure reducing regulator. We recommend a flow rate of 0.5 kg/day for monitoring.

In contrast to dry ice, gas cylinders can be stored until use with no trouble. This permits a flexible response to changes in the weather and makes it possible to use the traps at an ideal time. The gas cylinders are the same that are used for draught beer and the production of carbonated drinks in pubs and restaurants.

The following video guides you through the set-up and use of the BG-Sentinel trap with CO2 in natural environment:

This configuration of the trap is currently also being used by the Friederich-Löffler-Institute in the Germany-wide mosquito monitoring project called "Geographical and seasonal distribution of endemic and invasive mosquitoes in Germany". In this project, around 60 BG-Sentinels with a CO2 supply are being used at selected locations throughout Germany to determine the spectrum of the mosquito species. In 2011, the species captured in this project already included adults of the invasive species Aedes albopictus, Ae. japonicus and Culiseta longiareolata (Werner et al 2012).
Dry ice can also be used, if preferred. In this case, the gas can be liberated from an isolated container with dry ice 30 to 40 cm above the intake funnel of the trap.
For short term monitoring and in warm regions also yeast can be used as carbon dioxide source.


Ultraviolet (UV) light is an attractant for biding midges (Ceratopogonidae) and certain other insects. Biogents offers a kit with which the BG-Sentinel trap can be transformed sdinto a UV-trap. Among others, this version was used in the German bluetongue monitoring program during the outbreak beginning in 2006 (Mehlhorn et al. 2009) or to capture Culicoides for blood meal analyses (Santiago-Alarcon 2012).

UV-Light can also be used to monitor the presence of certain mosquito species.
