Description of parameters of the Distributed Hazards Model (DHM)

Timing

Time unit is one day, so 24/2 is 2 hours

  • B.t = 24/2
  • F.t = 24/1
  • R.t = 1.5
  • L.t = 24/1
  • O.t = 24/1
  • M.t = 24*2
  • S.t = 24/1

Flight Survival

Senescence

Wing Tattering

Blood Meal Size

  • bm_a = 7.5; shape parameter for beta-distributed blood meal size
  • bm_b = 2.5; shape parameter for beta-distributed blood meal size

Refeeding Shape

  • rf_a = 18; shape parameter for refeeding probability as function of blood meal size
  • rf_b = 10000; shape parameter for refeeding probability as function of blood meal size

Overfeeding Shape

  • of_a = 5; shape parameter for overfeeding death probability as function of blood meal size
  • of_b = 500; shape parameter for overfeeding death probability as function of blood meal size

Egg Batch

  • emt_m = 3; mean time to egg maturation
  • emt_v = 0.1; variance of egg maturation time
  • bs_m = 30; mean egg batch size
  • bs_v = 5; variance of egg batch size

Sugar Bout

Energetics

1/(Flights Using Full Reserves)

Mating

  • nMates = 1
  • M.s = .95 ; probability to set bStateNew = “S” post mating bout
  • M.p = .95 ;
  • M.d = 1 - dhmP$M.p ; probability to set bStateNew = “D” post mating bout
  • M.f = 1 - dhmP$M.s - dhmP$M.d ; probability to set bStateNew = “F” post mating bout

Swarming

  • maleM.s = 0.99 ; probability of successfully entering swarm
  • maleM.p = 0.95 ; probability of surviving maleFlightStress
  • If eDefPreG > 0, it defines a pre-gonogrophic energy requirement that could be filled up preGsugar or preGblood units from each sugar or blood meal.
    • eDefPreG = 0
    • preGsugar = 0
    • preGblood = 0

Estivation

  • Probability of surviving estivation
    • E.p = 0.5
  • Onset of the dry season; a day of the calendar year
    • Emax = 90
    • Eb = 0.9
  • End of Estivation; a day of the calendar year
    • eEndm = 180
    • eEndV = 30

Bout Parameters

  • B.s = .99 ; probability of successful blood feeding attempt bout: if successful calls the chooseHost routines, otherwise set hostID = 0
  • F.s = .99 ; probability of successful blood feeding search bout: if successful set bStateNew = “B”, otherwise no change
  • L.s = .99 ; probability of successful egg laying search bout: if successful set bStateNew = “O”, otherwise no change
  • O.s = .99 ; probability of successful egg laying attenpt bout: if successful calls oviposition and egg batch routines, otherwise no change
  • If skip0 is TRUE
    • dhmP$skipBatch = dhmP$maxBatch/3
