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"
  ]
}

Intervention_Name

string

NA

NA

MosquitoRelease

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"
  }
}

New_Property_Value

string

NA

NA

“”

An optional NodeProperty key:value pair that will be assigned when the intervention is applied. See NodeProperties and IndividualProperties parameters for more information.

{
  "New_Property_Value": "HasHealthCare:YES"
}

Released_Fraction

float

0

1

0

The fraction of the current population of mosquitoes to relEase (the population from the previous time step) The population depends on the gender of the mosquitoes being released. This depends on Released_Type being set to FRACTION.

{
  "Released_type": "FRACTION",
  "Released_Fraction": 0.4
}

Released_Genome

array of strings

NA

NA

[]

This defines the alleles of the genome of the vectors to be released. It must define all of the alleles including the gender gene. ‘*’ is not allowed. See Vector_Species_Params for more information.

{
  "Released_Genome": [
    [
      "X",
      "X"
    ],
    [
      "b0",
      "b0"
    ]
  ]
}

Released_Infectious

float

0

1

0

The fraction of vectors released that are to be infectious. You can only use this feature when Malaria_Model is NOT set to MALARIA_MECHANISTIC_MODEL_WITH_PARASITE_GENETICS.

{
  "Released_Infectious": 0.6
}

Released_Number

integer

1

100000000.0

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.

{
  "Released_Species": "gambiae"
}

Released_Type

enum

NA

NA

FIXED_NUMBER

Specifies the number of mosquitoes to release. Possible values are FRACTION and FIXED_NUMBER. When set to FRACTION, this specifies the fraction of the current population to release. When set to FIXED_NUMBER, specifies an exact count of mosquitoes to release.

{
  "Released_Type": "FIXED_NUMBER"
}

Released_Wolbachia

enum

NA

NA

WOLBACHIA_FREE

The Wolbachia type of released mosquitoes. Possible values are:

  • WOLBACHIA_FREE

  • VECTOR_WOLBACHIA_A

  • VECTOR_WOLBACHIA_B

  • VECTOR_WOLBACHIA_AB

{
  "Released_Wolbachia": "VECTOR_WOLBACHIA_A"
