Two strains of the diamondback moth Plutella xylostella were selected for fast or slow developmental speed. The egg-larval period in the 7th generation of the fast-development strain (PxTF) was 16.0 days, which was 0.9 days shorter than that before selection (16.9 days), and that of the slow development strain (PxTS) was 20.5 days, which was 3.6 days longer than that before selection. The female forewing length in the 10th generation of PxTF was longer than that in the 8th generation of PxTS. The pupation rate in the 8th generation of PxTS was only 65.9%, whereas in the 10th generation of the PxTF it was 95.2%.
