The female lays its eggs in three whorl depositing 15-22 eggs in each whorl on the lower side of the leaf. On a single leaf as many as 150 whorls or 3000 eggs may be deposited by different females.

The nymphs from the eggs laid hatch in 7-14 days in different months and the nymphal stage is completed in 38-60 days. The pupal stage lasts 99-161 days. The insect hibernates in nymphal stage.

Production procedure

Aleurocanthus woglumi has been produced on lemon plants. The plants are grown in soil filled perforated polythelene bags or in nursery, when they are about one year old they are sprayed with dichlorvos to kill any other insect colonizing the seedlings. The seedlings are then exposed (after 5 days of spray) to pure culture of adult A. woglumi maintained. The adult A. woglumi deposits several eggs on the under surface of the succulent leaves. After 24 hours, the adults are aspirated out and A. woglumi on the plants are allowed to develop.
