Table 1 Main parameters and parameter values used in the evaluation
| Â | Description | Source of values |
|---|---|---|
Δoutdoors | The diversion that occurs outside the house when the mosquito is attempting house entry | Derived |
Δindoors | The diversion that occurs indoors when the mosquito has already entered the house to attack the human indoors | Derived |
M | The total number of malaria vectors caught in a given human occupied hut | Implied |
M 0 | The total number of malaria vectors caught in a given hut or set of huts having no protective treatment inside. | Actual numbers of female Anopheles arabiensis mosquitoes caught in unsprayed experimental huts fitted with untreated nets (Okumu et al., unpublished). M 0 values are considered equivalent to M 1 |
M 1 | The total number of malaria vectors caught in a given hut or set of huts having untreated mosquito nets as the only form of protection inside. Subscripts 2….n can be used to denote any other protective measures apart from untreated nets denoted by subscript ‘1’ | |
M p | The total number of malaria vectors caught in a given hut or set of huts having a protective treatment inside. Subscripts 2….n can be used to denote any other protective measures apart from untreated nets denoted by subscript ‘1’ in M 1 | Actual number of female An. arabiensis caught in experimental huts that have different LLINs, IRS insecticides or various combinations of different LLINs and different IRS insecticides. |
M p,y | Total number of malaria vectors that are considered to have entered the huts and attacked the humans inside the huts. They include female malaria vectors that are unfed and dead, blood fed and alive or blood fed and dead | |
M u,.l | Total number of malaria vectors that are caught unfed and were still alive after 24 hours. Classifiable as non-attacking vectors | |
M uf,d | Total number of malaria vectors that were caught unfed but died within 24 hours. Classifiable as fatal attacks | |
M f,l | Total number of malaria vectors that were caught when already blood fed and remained alive after 24 hours. Classifiable as successful attacks | |
M f,d | Total number of malaria vectors that were caught when already blood fed but died within 24 hours. Classifiable as fatal attacks |
