Different variations of Biogents' 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
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 and the Sweetscent .
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.
A controlled CO2
emission for monitoring endemic and invasive mosquito
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
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.
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:
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.
