From a case study to a theoretical basis for tsetse control

摘要: The paper presents a way of estimating average daily mortality rates female tsetse from ovarian age distributions. This technique was applied to monthly biconical trap samples G. palpalis taken during and after insecticidal campaigns in the Bouafle region Ivory Coast. A clear inverse relationship is demonstrated between annual mean number females per sample at 10 separate sites, calculated for them. Local variation impact insecticides explained terms grouping sites either side level natural above which populations cannot be sustained through reproduction alone. theoretical model density dependent population growth presented particular control situation, that sterile insect release method. demonstrates effectiveness any induced sterility (or mortality) crucially determined by resilience target population.
