SpaceSpraying

The SpaceSpraying intervention class implements node-level vector control by spraying pesticides outdoors. This intervention targets specific habitat types, and imposes a repellent effect or mortality rate on all targeted mosquitoes.

Note

Parameters are case-sensitive. For Boolean parameters, set to 1 for true or 0 for false. JSON does not permit comments, but you can add “dummy” parameters to add contextual information to your files.

The table below describes all possible parameters with which this class can be configured. The JSON example that follows shows one potential configuration.

Parameter Data type Minimum Maximum Default Description Example
Habitat_Target enum NA NA TEMPORARY_RAINFALL

The larval habitat type targeted for habitat reduction. This is a required parameter. See Larval habitat parameters for more information. Possible values are:

  • TEMPORARY_RAINFALL
  • WATER_VEGETATION
  • HUMAN_POPULATION
  • CONSTANT
  • BRACKISH_SWAMP
  • MARSHY_STREAM
  • LINEAR_SPLINE
  • ALL_HABITATS
{
    "Habitat_Target": "WATER_VEGETATION"
}
Spray_Kill_Target enum NA NA SpaceSpray_FemalesOnly

The gender kill-target of vector control interventions. Possible values are:

  • SpaceSpray_FemalesOnly
  • SpaceSpray_MalesOnly
  • SpaceSpray_FemalesAndMales
  • SpaceSpray_Indoor
{
    "Spray_Kill_Target": "SpaceSpray_FemalesAndMales"
}
Killing_Config JSON object NA NA NA The configuration of killing efficacy and waning for space spaying. Specify how this effect decays over time using one of the Waning effect classes.
{
    "Killing_Config": {
        "Box_Duration": 3650,
        "Initial_Effect": 0.5,
        "class": "WaningEffectBox"
    }
}
Reduction_Config JSON object NA NA NA The configuration of larval habitat reduction and waning for space spraying. Specify how this effect decays over time using one of the Waning effect classes.
{
    "Reduction_Config": {
        "Box_Duration": 100,
        "Decay_Time_Constant": 150,
        "Initial_Effect": 0.1,
        "class": "WaningEffectBoxExponential"
    }
}
Cost_To_Consumer float 0 999999 10 The unit cost per vector control (unamortized).
{
    "Cost_To_Consumer": 8
}
Primary_Decay_Time_Constant float 0 1.00E+0 0 The primary decay time constant (in days) of the decay profile.
{
    "Primary_Decay_Time_Constant": 180
}
Secondary_Decay_Time_Constant float 0 999999 1 The secondary decay time constant of the durability profile. This parameter is used when Durability_Profile is set to CONCENTRATION_VERSUS_TIME.
{
    "Durability_Profile": "CONCENTRATION_VERSUS_TIME",
    "Secondary_Decay_Time_Constant": 730
}
Disqualifying_Properties string NA NA NA A list of IndividualProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to individuals with these values). See NodeProperties and IndividualProperties parameters for more information. Generally used to control the flow of health care access. For example, to prevent the same individual from accessing health care via two different routes at the same time.
{
    "Disqualifying_Properties": [
        "InterventionStatus:LostForever"
    ]
}
Intervention_Name string NA NA NA The optional name used to refer to this intervention as a means to differentiate it from others that use the same class.
{
    "Intervention_Name":"Diagnostic_Sample"
}
New_Property_Value string NA NA NA An optional IndividualProperty key:value pair that will be assigned when the intervention is distributed. See NodeProperties and IndividualProperties parameters for more information. Generally used to indicate the broad category of health care cascade to which an intervention belongs to prevent individuals from accessing care through multiple pathways. For example, if an individual must already be taking a particular medication to be prescribed a new one.
