The life history of Pseudaulacaspis pentagona (Targioni) was studied. Activities of scale crawlers, the development of the scale cover, and the sex activity are described. The time required for a complete generation ranged from 49 to 51 days. The scale was observed infesting 21 different species of plants. Local parasites and predators are listed. Several insecticides were investigated for control; ethion plus oil gave the best control.
