Effects of Introducing Trehalose Gene into Rice on the Life History of Plodia interpunctella (Lepidoptera: Pyralidae) and Sitophilus zeamais (Coleoptera: Curculionidae)

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 . Development of the both two insects was significantly delayed; on T-Nakdong, the developmental periods of female moth and weevil were , respectively. Whereas those on Nakdong were , respectively. Net reproduction rate of Indian meal moth on T-Nakdong was significantly lower than that on Nakdong , due to the lower emergence rate . 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.
