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®. Evaluations were conducted between July and September 2015 under field conditions within a suburban area in southeastern Virginia. The 4 traps were compared with their respective lure systems (BGS, BGSP, and BGS2 with BG-Lure cartridge; SNAP with BG-Sweetscent). No significant differences were seen in total female mosquito collections among the 3 BG-Sentinel models. All 3 Sentinels collected significantly more female mosquitoes than the SNAP (P ≤ 0.009); BGS and BGS2 both collected significantly more Aedes albopictus females than the SNAP (P ≤ 0.02). The 2 lures were compared in both BGS2 and SNAP traps. Although both lures performed significantly better in the BGS2 trap (P ≤ 0.0003), there were no significant differences in number of mosquitoes or species composition collected with BG-Sweetscent and BG-Lure cartridge within the same trap type.
