Activities of Cry55Aa1, Cry6Aa2, and Cry5Ba2 against Meloidogyne haplab
| Crystal protein | Regression equation | Regression coefficient | LC50 (μg/ml)a |
|---|---|---|---|
| Cry55Aa1 | y = 2.6911x + 1.4288 | 0.9789 | 23.2 |
| Cry6Aa2 | y = 1.8736x + 2.4415 | 0.9711 | 23.9 |
| Cry5Ba2 | y = 1.6544x + 2.9475 | 0.9692 | 18.1 |
The second-stage juvenile of Meloidogyne hapla was tested, and LC50s were determined on the fifth day.
Bovine serum albumin (BSA) was used as the negative control; it has no toxicity to Meloidogyne hapla.
