Laboratory investigation on the developmental period of T. ni Hubner on 3 host plants, i.e., sunflower (Helianthus annuus), lima bean (Phaseolus lunatus) and radish (Raphanus sativus) leaves were conducted at room temperature (21 .+-. 2.4.degree. C). Larval period was shortest (13.22 days) on radish and longest on lima bean (16.57 days). The percentage pupation ranged from 42-54% on lima bean and radish, respectively. Pupal weight was the highest (161.97 mg) and pupal period shortest (6.97 days) on radish. The total period required to complete the life cycle (egg-adult emergence) was 21.22, 25.40 and 26.37 days on radish, sunflower and lima bean, respectively. Females lived longer than males.
