Two lepidopteran species, Matsumuraeses phaseoli (Matsumura) and Maruca vitrata (syn. M. testulalis) (Fabricius) were reared on artificial diets, and analyzed in their developmental characteristics. Photoperiod was supplied with 16L/8D for M. phaseoli and with 13L/11D for M. vitrata, respectively. Both species passed five larval instars with discrete sizes of head capsule width. In a constant environment (25℃ and 65%RH), the developmental period of M. phaseoli egg, larva and pupa was 3.9, ca. 16.0 and 8.9 days, respectively, and over 80% of M. phaseoli larvae could develop into pupae, most of which emerged into adults.
