Table 1 Percentages of male and female pupae (mean ± standard error) of Ae. aegypti and Ae. albopictus, separated at different pore sizes by the standard sieving method

From: Use of mechanical and behavioural methods to eliminate female Aedes aegypti and Aedes albopictus for sterile insect technique and incompatible insect technique applications

Species (N = 1500) Percentage of male and female pupae retained
Pore size, mm Percentage of retained pupae Pupal mortality (%)
Male pupae in sieve (%) Female pupae in sieve (%)

1.12 73 ± 3.5 (n = 438) 28 ± 2.5 (n = 196) 4 ± 0.5 (n = 60)
1.25 1 ± 0.2 (n = 6) 63 ± 3.6 (n = 441) 3 ± 0.8 (n = 45)
