BG-Sentinel: The researchers' mosquito trap

A result of more than 15 years of academic research into the host-finding of mosquitoes, the BG-Sentinel (a.k.a. the BG trap or BGS trap) is a mosquito trap used by mosquito professionals worldwide.

The BG-Sentinel mosquito trap
  • mimics convection currents created by a human body
  • employs attractive visual cues
  • releases artificial skin emanations through a large surface area
  • can be used without CO2 to specifically capture selected mosquito species
  • is an excellent general mosquito trap when used with CO2

Introduction

Used in combination with the BG-Lure cartridge, a dispenser which releases a combination of non-toxic substances that are also found on human skin (ammonia, lactic acid, and caproic acid), the BG-Sentinel is especially attractive for the yellow fever (or dengue) mosquito, Aedes (Stegomyia) aegypti, the Asian tiger mosquito, Aedes (Stegomyia) albopictus, the southern house mosquito, Culex quinquefasciatus, and selected other species. With the addition of carbon dioxide, the BG-Sentinel is an exellent surveillance tool for mosquitoes in general.

The BG-Sentinel mosquito trap is essentially a collapsible, white fabric container with a white gauze covering its opening. The diameter is 36 cm (14 inches), the height 40 cm (1.3 feet). In the middle of the gauze cover, air is sucked into the trap through a black catch pipe by an electrical fan, drawing approaching mosquitoes into a catch bag. Unlike in other monitor traps, the catch bag is located above the fan, the catch can be controlled easily, the captured mosquitoes remain intact and well preserved for analyses.

The air then exits the trap through the white gauze, generating ascending currents. These are similar to convection currents produced by a human host, both in its direction, its geometrical structure, and, due to the addition of the BG-Lure, also in its chemical composition.

Interesting for professional researchers and mosquito specialists: the BG-Sentinel is large enough to incorporate additional attractants such as fragrant substances, small living animals, worn clothing, animal hairs, light and heat sources, etc. This makes the trap a very versatile tool for both monitoring and research.

Features, applications and options

Different variations of the 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 attractant 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).
All variations and available accessories can be found in the product catalog for researchers.
