A set of discrete formulae that calculates the hypothetical impact of aerialspraying on a tsetse population is derived and the work is thought to be novel.Both the original population and the subsequent generations which survive theaerial spraying, may ultimately be thought of as deriving from two, distinctsources. These origins are, however, neither distinct, nor relevant by thethird generation. It is for this reason that the female population isconsidered to be composed of the following four categories for the purposes ofderivation: Original flies which existed as such at the commencement ofspraying; original pupae which existed as such at the commencement of spraying;the immediate descendants of both the aforementioned categories, duringspraying; third and higher generation descendants. In theory, the lattercategory is a recurrence relation. In practice, the third generation's pupalstage has hardly come into existence, even by the end of a completed operation.Implicit in the formulae is the assumption of one, temperature-dependentmortality rate for the entire pupal stage, a second for the period betweeneclosion and ovulation and yet a third for the entire, adult life-span. Gravidfemale resistance to the insecticide is assumed to be inconsequential. Afurther assumption of the formulae is that at least one male is alwaysavailable (degree of sterility variable).
