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.

Parameter	Data type	Minimum	Maximum	Default	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_Ratio	float	0	3.40E+038	0	The number of released mosquitoes is proportional to the mosquito population from the previous timestep, specifically considering mosquitoes of the same gender as those being released. This approach is used when on Released_Type is set to RATIO.	{ "Released_type": "RATIO", "Released_Ratio": 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" }
