  The biology of indian meal moth and maize weevil on the trehalose gene introduced rice (var "Nakdong") (T-Nakdong) was compared to that on the rice without gene introduction (Nakdong) at 28±1.0℃. Development of the both two insects was significantly delayed, on T-Nakdong, the developmental periods of female moth (±SE) and weevil were 38.46±0.42 and 36.38±0.28 days, respectively. Whereas those on Nakdong were 36.38±0.28 and 34.33±0.18, respectively. Net reproduction rate of Indian meal moth on T-Nakdong (3.0±0.14) was significantly lower than that on Nakdong (9.25±0.13), due to the lower emergence rate (21.08±0.04% vs 48.30±0.06%). The life table statistics of maize weevil on T-Nakdong was estimated to be similar to those on Nakdong. The delayed development of T-Nakdong suggested that the factor for development of the insects could be changed by the introduction of trehalose gene into the rice variety.
