The model is used to estimate the straight-line distance traveled in the life span of a fly, and the distance fly populations will spread during a 10-yr period. Simulation results indicate that the straight-line distance traveled in the life span of a tsetse fly is <1.71 km from its birth place. The spread distance for fly populations is ≈18.7 km by the end of the 10th yr based on a 99% confidence prediction limit. Strategies of preventing tsetse flies from advancing to a tsetse-free region are examined. The probabilities that a fly crosses a protective barrier (buffer zone) are obtained for different control methods. The width of a protective barrier required to prevent the tsetse flies from advancing to a tsetse-free region is estimated. © 1996 Entomological Society of America Population Ecology nationallicence Glossina nationallicence spatial spread nationallicence trypanosomiasis nationallicence vector control nationallicence protective barrier nationallicence Yu Peter Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Habtemariam Tsegaye Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Oryang David Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Obasa Mike Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Nganwa David Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Robnett Vinaida Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut Environmental Entomology Oxford University Press 25/1(1996-02-01), 78-84 0046-225X 25:1<78 1996 25 ee https://doi.org/10.1093/ee/25.1.78 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/ee/25.1.78 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Yu Peter Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 700 1- Habtemariam Tsegaye Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 700 1- Oryang David Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 700 1- Obasa Mike Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 700 1- Nganwa David Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 700 1- Robnett Vinaida Center for Computational Epidemiology, School of Veterinary Medicine, Tuskegee University, Tuskegee, AL 36088 aut NATIONALLICENCE 773 0- Environmental Entomology Oxford University Press 25/1(1996-02-01), 78-84 0046-225X 25:1<78 1996 25 ee Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
