The Aedes mosquito vectors of dengue virus (DENV) and chikungunya virus (CHIKV) are attracted to specific host cues that are not generated by traditional light traps. For this reason multiple companies have designed traps to specifically target those species. Recently the standard trap for DENV and CHIKV vectors, the BG-Sentinel (BGS) trap, has been remodeled to be more durable and better suited for use in harsh field conditions, common during military operations, and relabeled the BG-Sentinel 2 (BGS2). This new trap was evaluated against the standard Centers for Disease Control and Prevention (CDC) light trap, Zumba Trap, and BG-Mosquitito Trap to determine relative effectiveness in collecting adult Aedes aegypti and Ae. albopictus. Evaluations were conducted under semifield and field conditions in suburban areas in northeastern Florida from May to August 2014. The BGS2 trap collected more DENV and CHIKV vectors than the standard CDC light trap, Zumba Trap, and BG-Mosquitito Trap, but attracted fewer species, while the BG-Mosquitito Trap attracted the greatest number of mosquito species.

The BG-Sentinel® (BGS) trap has recently been redesigned for increased durability and ergonomic functionality, marketed as the BG-Sentinel 2® (BGS2). We evaluated the trapping performance of these 2 traps in addition to the BG-Sentinel prototype (BGSP), a model similar to the BGS2 that was beta tested in several US states in 2014, and the BG-SNAP (SNAP), which is a prototype revision of the BG-Mosquitito™. We also evaluated 2 new Biogents AG lures: the BG-Lure cartridge and BG-Sweetscent™, as they are granular formulations replacing the original mesh BG-Lure®.

The efficacy of the BG-Sentinel (BGS) and the BG-Mosquitito (BGM) mosquito traps for sampling populations of the important filariasis and dengue vector Aedes (Stegomyia) polynesiensis (Marks) was evaluated in French Polynesia against human bait collections (HBC) using a modified Centers for Disease Control and Prevention backpack aspirator. Traps were baited with BG-Lure (a combination of lactic acid, ammonia, and caproic acid) or carbon dioxide plus octenol (1-octen-3-ol) known as attractants to aedine mosquitoes. Mosquito sampling was conducted on two typical islands of French Polynesia: the high, volcanic island of Moorea, and the low, coral island (atoll) of Tetiaroa Sampling efficacy was measured in a randomized Latin Square design.
