SpaceSpraying

The SpaceSpraying intervention class implements node-level vector control by spraying pesticides outdoors. This intervention targets specific habitat types, and imposes a mortality rate on all targeted (both immature and adult male and female) mosquitoes. All mosquitoes have daily mortality rates; mortality for adult females due to spraying is independent of whether or not they are feeding.

At a glance:

  • Distributed to: Nodes
  • Serialized: No. You need to redistribute when starting from a serialized file.
  • Uses insecticides: Yes. It can target sub-groups using genomes, especially if you want to target specific sexes.
  • Time-based expiration: No
  • Purge existing: Yes and No. Adding a new intervention of this class will overwrite any existing intervention of the same class with the same Intervention_Name. If Intervention_Name is different, both interventions will coexist and their efficacies will combine 1-(1-prob1)*(1-prob2) etc.
  • Vector killing contributes to: Die Without Attempting To Feed & Die Before Attempting Human Feed
  • Vector effects: Killing
  • Vector sexes affected: Males and females
  • Vector life stage affected: Adult and immature

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 Type Min Max Default Description
Cost_To_Consumer float 0 999999 10 The unit cost per vector control (unamortized).
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 IndividualProperties and NodeProperties 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.
Dont_Allow_Duplicates boolean 0 1 0 Prevents individual from receiving a new intervention with the same Intervention_Name.
Insecticide_Name string NA NA Uninitialized string The name of the insecticide defined in for this intervention. If insecticides are being used, this must be defined as one of those values; if they are not being used this can be empty. It cannot have a value if you did not configure .
Intervention_Name string NA NA SpaceSpraying The optional name used to refer to this intervention. If two interventions of this class have different Intervention_Name values, this allows them to co-exist in the node. Otherwise the new intervention replaces the existing one.
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.
New_Property_Value string NA NA "" An optional NodeProperty key:value pair that will be assigned when the intervention is applied. See IndividualProperties and NodeProperties parameters for more information.
Spray_Coverage float 0 1 0 The portion of the node that has been sprayed. This value is multiplied by the current efficacy of the WaningEffect.
