Laboratory study reveals selective breeding for protandry reduces female contamination to under one percent in Aedes albopictus, suggesting improved sterile insect technique scalability.

Key Points

To evaluate whether selective breeding for pupal size dimorphism and protandry can enhance male-female separation efficiency in Aedes albopictus.
Selected and crossed small males with large females to enhance size dimorphism, and early pupating males with late pupating females to increase protandry.
Adjusted the standard egg hatching period from 14–16 h overnight to 4 h to synchronize larval development without decreasing egg hatch rates.
Harvested pupae 24 h after the onset of pupation without mechanical sieving to evaluate harvest yield and female contamination against an unselected control strain.
Harvesting at 24 h yielded 28.50% pupae relative to initial first instar larvae in the selected strain compared to 26.49% in the control strain.
Female contamination in the harvested pupae fell to 0.92% in the protandric selected strain compared to 23.02% in the control strain.
