TABLE 2.
Comparison of LC50s estimated from bioassays performed with first-instar larvae of T. ni, in which Cry1Ac1 was used alone and in combination with two concentrations of Cyt1A1
| Toxin(s)a | LC50 (ng/cm2) | SD | Coefficient of variation (%) | Statistical significanceb |
|---|---|---|---|---|
| Cry1Ac1 | 2.412 | 0.26 | 10.7 | A |
| Combination I | 19.051 | 3.3 | 17.3 | B |
| Combination II | 15.643 | 3.5 | 22.2 | B |
a
For combination I Cry1Ac1 was mixed with 1.0 μg of Cyt1A1 per cm2; for combination II Cry1Ac1 was mixed with 0.1 μg of Cyt1A1 per cm2.
b
Different letters indicate that values were statistically different (P = 0.99, as determined by the Tukey test).
