Abstract

A discrete population of Aedes triseriatus was studied in a 10-ha oak woodlot containing 108 tree holes. Markrelease-recapture methods showed a population of 1225 adult females in late summer of 1975 (Sinsko & Craig 1978). In studies of immature stages, the period from hatching to pupation was 9 weeks in the spring but considerably shorter in midsummer. The sex ratio was distorted in favor of males in the spring, approached 1:1 in midsummer and then increased in favor of females at the end of the season. Tree hole productivity varied markedly, with 83% of pupae coming from 23% of tree holes. Photoperiod-induced diapause prevented all egg hatching after 3 August 1975; at this time, the photoperiod was 14L:10D.
