Abstract

A study of the age-dependent changes in the ovarioles and the age structure of a population of adult females of Anopheles gambiae in the Amani hills of north-eastern Tanzania was undertaken using the ovarian oil injection technique. The greatest difficulties encountered in accurately determining the age of members of this species are due to small size and the low parity diagnostic index of the ovary, which decreased in successive gonotrophic cycles and could drop to zero even in the first cycles. Additional information can be obtained from basal bodies, groups of six to eight cells in the calyx wall enclosed by the end of the ovariolar sheath. The possibility exists of their use for age grading of mosquitoes. The mean age of the population during the study, which was carried out in the rainy season, was rather low. The oldest were individuals that had completed four ovipositions. Among the mosquitoes infected with sporozoites were females that had completed between ≥2 and ≥4 ovipositions.
