Abstract
MACDONALD1 has shown that the composition of mosquito populations, as regards the proportion in the parous state, can be calculated theoretically, yielding an equation which involves the daily survival-rate and a time period based on the gonotrophic cycle. This, and a modified equation given by Davidson2, have provided a useful means for calculating daily survival rates in the field. Using similar methods, it is possible to derive a general expression which determines the composition of populations as regards the proportion in the unfed condition.
