Background information on artificial human skin scents

Biogents developed artificial scents that mimic human skin odors. Using special formulation technology and scent dispensers, attractant components are released in precisely the right amounts to produce a finely tuned mixture of scents which increase the capture rates of mosquito traps especially for Ae. albopictus and Ae. aegypti.

BG-Sweetscent increases catch rates of many traps for Aedes aegypti and Aedes albopictus

The BG-Sweetscent is the first attractant targeting Aedes aegypti and Ae. albopictus that has been scientifically proven to work with many different mosquito traps:
Scientific studies show that using our attractant BG-Sweetscent in a variety of commercially available mosquito traps can increase catch rates of mosquitoes that transmit diseases like dengue, Zika or chikungunya.

Studies

Two studies from independent organizations in Florida and Louisiana showed the effect of the BG-Sweetscent on different traps with similar study design:
Each trap was tested with and without the BG-Sweetscent attractant:

  • tests were designed as Latin square tests
  • no CO2 was added to the traps
  • trap types: suction trap and zapper trap

1) Study #1 conducted in Gainesville, FL, showed increased catch rates for Ae. albopictus in traps with BG-Sweetscent in comparison to the same traps without BG-Sweetscent:

Results of a study in Gainsville, Fl, USA with the BG-Sweetscent and several commercially available traps. The catch rates for tiger mosquitoes could be improved by up to 4.2 fold when BG-Sweetscent was added to the traps.2) Study #2 conducted in Lake Charles, LA, showed increased catch rates for Ae. albopictus in traps with BG-Sweetscent in comparison to the same traps without BG-Sweetscent:

Results of a study in Lousiana, USA with the BG-Sweetscent and several commercially available traps. The catch rates for tiger mosquitoes could be improved by up to 4.2 fold when BG-Sweetscent was added to the traps.Source:

Detailed information on BG-Sweetscent

BG-Sweetscent is effective for up to two months. It comes as a sachet filled with three attractive components in granular form, and offers the following features:

  • a natural emission pattern – the release pattern of the cocktail of active molecules is designed to resemble the natural emission of human skin odors
  • protection against enviromental influence – the waterproof envelope allows a diffusion of the components through the membrane, and at the same time the components are protected against rain, humidity, and light
  • excellent emission profile – the components are formulated into special polymers that provide a controlled release of the active ingredients.

The BG-Sweetscent consists of polymer particles that provide a uniform mixture of the components.
