Abstract

The results derive from three 24-h catches of Aedes aegypti (L.) (1190 females, 504 males) using human bait at Buguruni, Dar es Salaam, Tanzania, in April 1971. The diel periodicity of all females is predominantly diurnal (at least 99·83% arrive during daylight or twilight) and bimodal, with consistent peaks at 06.00–07.00 h (post-sunrise) and 17.00–18.00 h (pre-sunset). The diel periodicities of nullipars and pars, and of uninseminated and inseminated females are virtually identical. The diel periodicity of males is also bimodal but differs from that of females in that at least two-thirds (instead of about half) of the individuals arrive between noon and sunset, more activity occurs between 09.00 and 15.00 h, and the post-sunrise peak falls at 08.00–09.00 h. A large influx of nullipars one afternoon did little to modify the close correspondence between the diel periodicities of nullipars and pars on subsequent days. Females land on bait in all ovarian stages (I–V), but in these catches more than 80% of nullipars and pars were almost equally divided between stages I and II. Among nullipars relatively more uninseminated females, and among pars relatively more with relict eggs, land in stage I than do so in stage II. It is inferred that pars with relict eggs usually expel them between stages I and II. This work reveals the likelihood that (at least at Buguruni) the frequency of potentially infective bites on a given day could be monitored with acceptable precision by limiting the catch to seven hours and the part that was age-graded to two hours.
