Abstract

Develops models to predict Glossina population loss rates under various trapping regimes. Parameters are the range of attraction of the traps, the mortality rate imposed by the traps, the rate at which the flies diffuse through an area, the fly population growth rate, and the distribution of the traps or targets. If the flies are very mobile and the traps relatively inefficient, the rate at which the fly population is reduced is limited by the range of attraction, the trapping mortality rate and the population growth rate; if the flies are relatively immobile and the traps very efficient, the rate of reduction is limited by the mobility of the flies and the population growth rate. The efficiency of barriers constructed from lines of traps or targets depends on the width of the barrier, the mobility of the flies and the mortality rate within the barrier. The authors investigate the rate at which a fly front will advance into country cleared of or previously unoccupied by flies and provide an explanation for observations regarding the relatively slow rate at which fly fronts advance. -from Authors
