Table 1. The median lethal times (LT50s) of the fungal strains Bb-Cyt2Ba and WT against Aedes mosquitoes (larvae or adults) at three concentrations.
| Mosquitoes | Fungal strains | LT50 (± standard error), day | ||
|---|---|---|---|---|
| (conidia/ml) | 1 x 108 | 1 x 107 | 1 x 106 | |
| Ae. aegypti adults | Bb-Cyt2Ba | 4.0 (±0.2) | 6.5 (±0.2) | 8.5 (±0.3) |
| WT | 6.0 (±0.1) | 8.0 (±0.5) | 16.0 (±1.3) | |
| Ae. aegypti larvae | Bb-Cyt2Ba | 3.5 (±0.3) | 6.0 (±0.7) | |
| WT | 6.0 (±0.2) | 8.0 (±0.5) | ||
| Ae. albopictus adults | Bb-Cyt2Ba | 4.0 (±0.3) | 5.0 (±0.3) | 10.0 (±0.5) |
| WT | 5.0 (±0.3) | 6.5 (±0.3) | 14.0 (±1.7) | |
| Ae. albopictus larvae | Bb-Cyt2Ba | 4.0 (±0.1) | 5.5 (±0.1) | |
| WT | 6.0 (±0.3) | 8.0 (±0.3) | ||
The difference in the LT50 between the Bb-Cyt2Ba and the WT strains at each concentration shown above is significant.
