TRANSCRIPT
The BG-Sentinel Trap
• Presented by Kirby Foley
BG–Sentinel Trap
• Developed and manufactured by BioGents in
Regensburg Germany www.biogents.com
• Sold here by BioQuip www.bioquip.com
• Developed over 15 years of research
• Originally designed to attract Aedes aegypti and Aedes albopictus
Assemble Trap
BG–Sentinel Trap
• Mimics convection currents created by a human
body
– The BG-Lure consists of a combination of ammonia,
lactic acid, and fatty acids (substances on human skin)
• Employs attractive visual cues
– Uses the black and white color scheme
• Releases attractants through a large surface
area
– 14 inch diameter area covered by gauze
Power Supply
• Power supply can be 120 AC or 12 volt battery
• Using the transformer and extension cord you
can trap 24 / 7 …let it function as the Mosquito
Magnet type trap or just overnight.
• We trapped 2 PM to 7 AM and used 12 volt
battery
BG–Sentinel Trap
• We received and started setting two traps in mid
August
• We set a total of thirty-six nights
• 21 nights we set a BG-Sentinel and a CDC trap
side by side for comparison (baited with CO2)
– The following slides will show the results:

BG-Trap Results
• More Ae. vexans, Ochlerotatus, Culex, Coquillettidia, and Psorophora with CO2
• 80 times more Aedes albopictus– We trapped 631 in one setting of one trap
– Ae. vexans and Ps. ferox really increase with use of CO2
• Equal number of Culiseta melanura (w/CO2)
• Less Anopheles, Cx. territans, and Ur. Sapphirina in BG-Sentinel
Results
• BG trap will average 300% more than CDC
• BG Trap with CO2 will average 34% more than BG Trap without CO2
• The BG-Sentinel Trap is a very good tool to have in your surveillance program
