For typical parameter values, the intrinsic growth rate of the population is zero when the adult daily survival rate is 0.970, corresponding to an adult life expectancy of 1/0.030 = 33.3 days. This value is plausible and consistent with results found earlier by others. The intrinsic growth rate is insensitive to the variance of the interlarval period. Temperature being a function of the time of the year, a known relationship between temperature and mean pupal and interlarval times was used to produce a time-varying version of the model which was fitted to temperature and (estimated) population data. With well-chosen parameter values, the modeled population replicated at least roughly the population data. This illustrates dynamically the abiotic effect of temperature on population growth. Given that tsetse flies are the vectors of trypanosomiasis ("sleeping sickness") the model provides a framework within which future transmission models can be developed in order to study the impact of altered temperatures on the spread of this deadly disease. specialized matrix model tsetse parity nonnegative matrix 052 020 204 2 215-231 2006 0025-5564 https://www.documentation.ird.fr/hor/fdi:010037749 10.1016/j.mbs.2006.08.022 0025-5564 [F A010037749] https://www.documentation.ird.fr/hor/fdi:010037749 https://www.documentation.ird.fr/intranet/publi/2007/02/010037749.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2007-03-01 2017-08-23 fdi:010037749 fre
