Maximum likelihood estimate (MLE) for bluetongue virus (BTV) and 95% confidence intervals from five species of Culicoides captured in CDC traps with and without light from 2016 to 2018 at the Bob R. Jones Idlewild Research Station near Clinton, LA
| Species | BTV with light | BTV no light | ||
|---|---|---|---|---|
| No. + pools (#spm.)a | MLE (CI)b | No. + pools (#spm) | MLE (CI) | |

| C. debilipalpis | 3 (301) | 12.1 (3.2–32.7) | 4 (398) | 9.5 (3.1–22.8) |
| C. haematopotus | 2 (25) | 76.9 (13.8–238.8) | 1 (17) | 73.4 (4.2–311.5) |
