“…The daily survival rate of 82.7% obtained in the present paper is almost identical to the 84% derived by Gillies & Wilkes (1965) from their classic age grading study in Muheza, on the northern coast of Tanzania, and the figure of 82% estimated from a more recent study in the same place (Lines et al, 1991). There is a remarkable similarity in survival rates of different anophelines in the tropics (Hii et al, 1990), but the slightly higher survival of those in tropical Africa means that they have a considerably higher vectorial capacity (Charlwood et al, 1985).…”

“…The ratio of the number of virgin insects collected on day t to the number of plug-blood insects collected on day t + 1 was used to estimate the survival rate of insects that fed as virgins and returned to feed immediately after mating. Estimates of mean oviposition cycle duration were determined using the formulae of Charlwood et al [27]. …”

“…The duration of the oviposition cycle in days, u, was estimated from the proportion (A) of mosquitoes in light traps with dilated ovariolar stalks ('a-sacs') as described by Charlwood et al (1985) for A. farauti. Females with sacs are assumed to have returned to feed on the day that they laid eggs (a 2 day cycle), whilst those without sacs are assumed to have delayed one day before attempting to refeed.…”

“…Since parous mosquitoes can be distinguished relatively easily by dissection from nulliparous ones it is feasible to examine large numbers and hence obtain precise estimates. Parous rates therefore probably provide the most reliable indirect estimate of daily survival as long as a number of conditions are met (Charlwood et al, 1985): nulliparous and parous mosquitoes must be sampled with equal efficiency; mosquito death rate must be independent of age (which in the Kilombero appears to be the case) (Charlwood et al, 1995a); data should be collected over a whole number of complete seasons; and a good estimate of the duration of the oviposition cycle must be available.…”
