*HLC, human landing catch. †Sampling methods were CDC Light traps, BG-Sentinel and Suna traps (Biogents, https://www.biogents.com), as well as HLC and larval emergence in laboratory. Each BG-Sentinel trap was baited with BG-MB5 attractant (Biogents) and a CO2 production system (>50,000 ppm) based on the fermentation of sugar, yeast, and agar. For larval emergence method, larvae were collected and reared in laboratory until imago emergence.
