| Control | 8 | y = 3.1067 + 2.1016x | 5 | y = 3.889 + 1.693x |
| N-terminal 39 | 8 | y = 3.0821 + 2.1326x | 530 | y = 4.0192 + 3.6x |
| C-terminal 154 | 28 | y = 0.9533 + 2.7963x | NAb | NA |
| C-terminal 220 | NA | NA | NA | NA |
Toxicity treatment was replicated five times with 20 first instar larvae each time. Mortality was recorded after 24 h of incubation.
NA, no activity.
