Vector control

The following parameters determine the characteristics of campaign interventions aimed at vector control, such as the homing endonuclease gene (HEG), sugar feeding, and Wolbachia infection. When, to whom, and how those interventions are distributed is determined by the campaign file.

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.

Parameter	Data type	Minimum	Maximum	Default	Description	Example
HEG_Fecundity_Limiting	float	0	1	0	The fractional reduction in the number of eggs laid by a female mosquito who is homozygous in the homing endonuclease gene (HEG). HEG_Model must be set to GERMLINE_HOMING, EGG_HOMING, DUAL_GERMLINE_HOMING, or DRIVING_Y.	{ "HEG_Model": "EGG_HOMING", "HEG_Fecundity_Limiting": 0.7 }
HEG_Homing_Rate	float	0	1	0	The fractional redistribution from heterozygous offspring to the homozygous homing endonuclease gene (HEG) behavior. HEG_Model” must be set to GERMLINE_HOMING, EGG_HOMING, DUAL_GERMLINE_HOMING, or DRIVING_Y.	{ "HEG_Model": "EGG_HOMING", "HEG_Homing_Rate": 0.4 }
HEG_Model	enum	NA	NA	OFF	This parameter determines the structure of homing endonuclease gene (HEG) dynamics. Possible values are: OFF No HEG dynamics occur. GERMLINE_HOMING Female mosquito allele applies homing and then the fraction of wild/half/full HEG progeny are generated from combining with the male allele. EGG_HOMING The fraction of wild/half/full HEG progeny are calculated and then homing is applied to bias half towards full. DUAL_GERMLINE_HOMING Both male and female alleles apply germline bias before calculating progeny. DRIVING_Y Homing is applied as a bias of otherwise heterozygous progeny to be Y-drive male eggs.	{ "HEG_Model": "EGG_HOMING", "HEG_Homing_Rate": 0.4, "HEG_Fecundity_Limiting": 0.9 }
Vector_Sugar_Feeding_Frequency	enum	NA	NA	VECTOR_SUGAR_FEEDING_NONE	The frequency of sugar feeding by a female mosquito. Used is used in conjunction with the SugarTrap and OvipositionTrap interventions. Vector_Sampling_Type must be set to TRACK_ALL_VECTORS or SAMPLE_IND_VECTORS. Possible values are: VECTOR_SUGAR_FEEDING_NONE No sugar feeding. VECTOR_SUGAR_FEEDING_ON_EMERGENCE_ONLY Sugar feeding once at emergence. VECTOR_SUGAR_FEEDING_EVERY_FEED Sugar feeding occurs once per blood meal. VECTOR_SUGAR_FEEDING_EVERY_DAY Sugar feeding occurs every day.	{ "Vector_Sugar_Feeding_Frequency": "VECTOR_SUGAR_FEEDING_NONE" }
Wolbachia_Infection_Modification	float	0	100	1	The change in vector susceptibility to infection due to a Wolbachia infection.	{ "Wolbachia_Infection_Modification": 1.0 }
Wolbachia_Mortality_Modification	float	0	100	1	The change in vector mortality due to a Wolbachia infection.	{ "Wolbachia_Infection_Modification": 0.0 }
