Macrogeographic population structure of thetsetseflypopulation groups 3 and 4 to show more diversities than the others.
From theCambridge English Corpus
The presence oftsetseflyand the semi-arid conditions of the region had historically precluded settlement by large populations.
From theCambridge English Corpus
With the definitions given in the previous section, consider a population where the initial generation consists of one femaletsetsefly.
From theCambridge English Corpus
The area-wide sampling oftsetsefly, aided by satellite imagery, is the subject of two separate papers.
From theCambridge English Corpus
The other estimates varied from two to 41 reproductive females and the lesser estimates are biased becausetsetseflygenerations greatly overlap.
From theCambridge English Corpus
However, there were substantial differences intsetseflydistribution and density between 1982 and 1996 (figs 2 and 3).
From theCambridge English Corpus
In this paper a simple density-dependent reinvasion model is described and used to estimatetsetsefly populations on the basis of removal trapping experiments.
From theCambridge English Corpus
They are transmitted between mammalian hosts by the bite of thetsetsefly.
From theCambridge English Corpus
It sets out to describe the environmental changes observed over the past 15 years by using recent and historical satellite data and to assess their impact ontsetseflypopulations.
From theCambridge English Corpus
In these circumstances a stochastic model is preferable and the simple life history of thetsetseflymakes it amenable to modelling as a branching process.
From theCambridge English Corpus
Where the geomorphological structure was not well suited to agricultural activity, riverine vegetation andtsetseflypopulations were relatively unaffected, even with intense agricultural activity nearby.

A study of thetsetseflyproblem.
From theCambridge English Corpus
It is not disputed that where thetsetseflyand game exist in a territory the keeping of domestic stock is not possible.

With regard to thetsetsefly, here again we can open up fresh areas for grazing, both by aircraft spraying and by antrycide.

I venture to suggest, in this connexion, that we should not be parsimonious in financing the research work in regard to thetsetsefly.
