Table 8 Fertility life table of Aedes aegypti groups with different pattern of temephos susceptibility

From: Fitness cost in field and laboratory Aedes aegypti populations associated with resistance to the insecticide temephos

Population/status for temephos   Parameters of population growth
  X (weeks) lX RO T (weeks) rm λ DT (weeks)
RecRev (susceptible) 4 0.82 45.8 3.5 1.1 3 0.63
RecRNEx (resistant non-exposed) 4 0.54 21.9 3.1 0.99 2.7 0.69
RecR (resistant exposed) 4 0.38 15.8 2.9 0.95 2.6 0.72
Arcoverde (resistant field) 4 0.65 17.4 3.2 0.89 2.4 0.77
  1. X = age interval of females; lx = survival rate during stage x; Ro = net reproductive rate; T = mean duration of each generation; rm = intrinsic rate of natural increase; λ = finite rate of increase; DT = doubling time or the period required for a population to double in size
