The embryonic and postembryonic developments of Nezara antennata Scott were observed in 5 different rearing cages such as A (Cylindrical, ${phi};10cm{ imes}4cm$), B (Cylindrical, ${phi};14.5cm{ imes}2.8cm$), C (Rectangle, $6.5L{ imes}6.5cmW{ imes}10cmH$), D (Cylindrical, ${phi}$ 9cm in bottom & ${phi}$ 11.5 cm in $upper{ imes}10.8cm$) and E (Cylindrical, ${phi};15cm{ imes}7.5cm$) containing soybean and peanut seeds as food, and sponge soaked with water under laboratory condition of $24^{circ}C$ and 15L : 9D. Hatchability ranged from 93 to 97%. Nymphal duration was shortest of 6 days in the 1st instar and longest of 10 days in the 5th instar. The nymphal duration was 38 to 39 days observed in the rearing cages. Emergence rate was in the range from 53 to 62% with highest in A and B cages. Adult longevity was 65 to 75 days for male, and 67 to 74 days for female, and was longest in the B cage. Total number of eggs laid by female adult was in the range from 51 to 56 without significant difference in the rearing cages, and was the most in the B cage. Accordingly, the reproductive rate of N. antennata for 1 generation was within 25 to 33 times, and was highest in the B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of N. antennata under laboratory condition.
