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. Minimum, maximum, or default values of “NA” indicate that those values are not applicable for that parameter.

EMOD does not use true defaults; that is, if the dependency relationships indicate that a parameter is required, you must supply a value for it. However, many of the tools used to work with EMOD will use the default values provided below.

JSON format does not permit comments, but you can add “dummy” parameters to add contextual information to your files. Any keys that are not EMOD parameter names will be ignored by the model.

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
Cost_To_Consumer	float	0	999999	10	The unit cost per vector control (unamortized).	{ "Cost_To_Consumer": 8 }
Disqualifying_Properties	array of strings	NA	NA	[]	A list of NodeProperty key:value pairs that cause an intervention to be aborted (persistent interventions will stop being distributed to nodes 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" ] }
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 LINEAR_SPLINE ALL_HABITATS	{ "Habitat_Target": "WATER_VEGETATION" }
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_Config": { "class": "SpaceSpraying", "Intervention_Name": "Outdoor DDT spraying" } }
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" } }
New_Property_Value	string	NA	NA	NA	An optional NodeProperty 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.	{ "New_Property_Value": "InterventionStatus:None" }
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" } }
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" }
