Abstract
An explanation is given of the probable effects of seeding a breeding place of Anopheles gambiae with hybrid eggs that produce almost exclusively sterile males. For the calculations, the dynamics of an A. gambiae population in a single breeding place have been simulated in a computer programme.
General considerations and implications are discussed with reference to practical applications, and the conclusion is reached that it will be feasible to eradicate the species from any breeding place only if the number of factory-produced eggs distributed daily bears a known, optimal relationship to the numbers deposited daily on the site.
The period of treatment, if the first-day ratio of normal: factory-produced eggs is 1: 1, was estimated to be in the region of 9 weeks. Several runs of the computer have been condensed in a graph which might be used in the early evaluation of progress in the field.
