Use of a general model to examine control procedures for a cockroach population

  • R. J. Larter
  • P. R. Chadwick


A matrix model for populations is described. The model breaks the population into an appropriate number of stadia to allow for reproductive cycles and includes individual daily survival rates and simple density dependence together with migration. Mortality due to insecticidal treatments may be applied on specified days to simulate space spraying while residual insecticides may be simulated with constant or declining effect. The use of the model is exemplified using a simulated population ofBlattella germanica with various treatment regimes. This simulation emphasised the importance of immigration.
