Examples of Mosquito Density Metrics Used to Inform Control Efforts
| Mosquito metric | Lower limits | Upper limits |
|---|---|---|
| Ovitrap indexa | <10% | >30–50% |
| BG traps | ? | ∼1 Ae. aegypti/trap per night |
| Pupae/personb | <0.05 | 1–2 pupae/person |

The Ministry of Health in Malaysia recommends intervention in levels exceeding 10% (Tee et al. 1997: Vector Control Unit, Ministry of Health, Malaysia).
b
Theoretical dengue epidemic transmission threshold ranges from 0.06–23.3, dependent on temperature and immunity in human population (Focks et al. 2007).
