| Carbamate | 1 G3 | 1 Akron | 2 RR |
|---|---|---|---|
| propoxur | 3.2 (2.4–4.2)3 | 201 (138–295) | 63 |
| terbam | 4.5 (3.6–5.4)3 | 223 (202–245) | 50 |
| carbaryl | 4.1 (3–5)3 | 186 (131–253) | 45 |
| bendiocarb | 0.74 (0.52–0.97)3 | 35 (25–48) | 47 |
| carbofuran | 0.85 (0.7–1.1)3 | 69 (48–95) | 81 |
| aldicarb | 0.52 (0.4–0.74) | 0.61 (0.41–1.2) | 1.2 |
| methomyl | 0.48 (0.35–0.64) | 0.67 (0.52–0.97) | 1.4 |

Topical LD50 values are ng/insect (95% confidence limits), essentially ng/mg for the size insects reared for this study.
2
RR is the resistance ratio: LD50 Akron/LD50 G3.
