Samples of replete adults, eggs, and larvae of A. variegatum were immersed in 500 ml of water for different durations (3, 6, 12, 24, 48, 72, and 96h), then dried and incubated at 25-degrees-C, 85% RH. A second batch was immersed in 500 ml of different sodium chloride concentrations (0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) for periods as stated earlier and thereafter incubated. They were observed for preoviposition time, ovipositional pattern and time of egg eclosion. Results showed that replete females died only after 24 h flooding in water. Eggs were most resistant to flooding. Replete females and larvae were more tolerant to Nacl solution than the eggs. ER -
