Abstract

The most suitable temperature for larval development of Aedes flavescens was found to be 20 °C. At this temperature 74% of the larvae pupated in 20 days. At 15 °C the developmental period was 42 days with a survival rate of 54%. At 25 °C the developmental period was 22 days but the survival rate dropped to 7%. At 10 °C the developmental period was 80 days with a survival rate of 6%. At 5 °C and 30 °C mortality was 100% in the first instar stage. Adult males emerged from the pupae in three days at 25 °C, two days earlier than the females.
