The ecological factors affecting the distribution of bromeliads and the anophelines that breed in them in Trinidad are reviewed. It is noted that in defining the distribution of breeding in the bromeliad flora of any vegetation type the following factors have to be considered

  • (intrinsic differences among the various species of bromeliads as potential breeding places,
  • (the relative abundance and vertical distribution of these bromeliads,
  • (the vertical distribution of anopheline oviposition,
  • (the coincidence or noncoincidence of the vertical ranges of the plants and the mosquitoes.

These factors are considered quantitatively in an analysis of the breeding of in the bromeliad flora of Trinidad cacao plantations.

It is found that by carefully defining the distribution of breeding the amount of bromeliad destruction necessary for control may be materially reduced.
