MosquitoRelease

The MosquitoRelease intervention class adds mosquito release vector control programs to the simulation. Mosquito release is a key vector control mechanism that allows the release of sterile males, genetically modified mosquitoes, or even Wolbachia-infected mosquitoes. See Vector control configuration parameters for more information.

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.

Description

Example

Cost_To_Consumer

float

0

999999

0

The cost of each mosquito release.

 
{
    "Cost_To_Consumer": 1.5
}

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"
    ]
}

Dont_Allow_Duplicates

boolean

0

1

0

If an individual’s container has an intervention, set to true (1) to prevent them from receiving another copy of the intervention. Supported by all intervention classes.

 
{
    "Dont_Allow_Duplicates": 0
}

HEG

enum

NA

NA

WILD

HEG characteristics of released mosquitoes. Possible values are:

  • WILD

  • HALF

  • FULL

  • NotMated

        "class": "MosquitoRelease"
    }
}

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": "MosquitoRelease",
        "Intervention_Name": "Sterile male mosquito release"
    }
}

Mated_Genetics

JSON object

NA

NA

NA

The genetic properties of the mate if released mosquitoes have mated, e.g. HEG and pesticide resistance. The characteristics are set under ResistanceHegGenetics. Used when Released_Gender is set to VECTOR_FEMALE.

 
{
    "Mated_Genetics": {
        "HEG": "NotMated",
        "Pesticide_Resistance": "NotMated"
    }
}

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"
}

Pesticide_Resistance

enum

NA

NA

WILD

The pesticide resistance characteristics of released mosquitoes. Possible values are:

  • WILD

  • HALF

  • FULL

  • NotMated

 
{
    "Released_Genetics": {
        "HEG": "WILD",
        "Pesticide_Resistance": "WILD"
    }
}

Released_Gender

enum

NA

NA

NA

The gender of released mosquitoes. Possible values are:

  • VECTOR_FEMALE

  • VECTOR_MALE

 
{
    "Released_Gender": "VECTOR_FEMALE"
}

Released_Genetics

JSON object

NA

NA

NA

The genetic properties of the released mosquito, e.g. HEG and pesticide resistance. The characteristics are set under the ResistanceHegGenetics parameter.

 
{
    "Released_Genetics": {
        "HEG": "WILD",
        "Pesticide_Resistance": "WILD"
    }
}

Released_Number

integer

1

1.00E+0

10000

The number of mosquitoes released in the intervention.

 
{
    "Released_Number": 10000
}

Released_Species

string

NA

NA

NA

The name of the released mosquito species, such as “arabiensis”. The simulation configuration parameter, Vector_Species_Params, needs to contain that specific mosquito species as does the Vector_Species_Names array.

 
{
    "Released_Species": "gambiae"
}

Released_Sterility

enum

NA

NA

VECTOR_FERTILE

The sterility of released mosquitoes. Possible values are:
