Biogents’ patented capture method mimics the human being
All of the Biogents traps function according to the same patented counterflow principle:
A single fan sucks the attracted mosquitoes into a catch bag below the black suction column of the trap. The air stream is then diverted and exits the trap through the white upper surface made of fabric. This air stream mimics the typical scent plume that is produced by a warm human body. To the mosquitoes the trap looks just like a human being.
The contrast between the dark center and the light surface of the trap is an additional important attractive signal for the mosquitoes, and completes the capture method.
A scent dispenser inside the trap enriches the air stream with small amounts of substances like those also emanated by the human skin. These substances enhance as synergists the attractiveness of the traps. If they were used alone without the trap, e.g., disposed on a sticky surface, they would be ineffective.
Carbon dioxide from an artificial nose is added to the air stream in order to increase the spectrum of the mosquitoes captured, and maximize the capture rate. The emission rate corresponds to that of a toddler or an infant.
This unique combination was developed at the University of Regensburg in over 16 years of research. Its efficacy is confirmed by scientists and other experts throughout the world.
