N2 - The effect of temperature on the development and survivorship of immature Anopheles culcifacies was observed under constant and cycling laboratory conditions. Temperatures between 28 and 30°C were optimal for rapid, synchronous development and for relatively high survival from 1st instar through emergence. Suboptimal temperatures lengthened the duration of the 1st instar. Stage-specific vertical life tables were constructed for immatures collected from 2 irrigation systems in rural Punjab Province, Pakistan, from April 1979 to May 1980. Mortality rates were greatest among 3rd- and 4th-instar larvae and pupae. Disproportionately fewer 1st-instar larvae and pupae were collected during periods of drying and intensive irrigation, respectively. Age distribution patterns were related to differential dispersion patterns, predation and parasitism, and cannibalism.
