We investigated the effects of molting-hormone insecticide tebufenozide on fourth larvae of the midge C. flaviplumuon in growth development from fourth-instar to adult. Fourth-instar larvae were exposed test concentrations were chosen control, 10 $mu extrm{g}$$L^{-1}$, 30 $mu extrm{g}$$L^{-1}$, 60 $mu extrm{g}$$L^{-1}$ and 100$mu extrm{g}$$L^{-1}$. In control and 10 $mu extrm{g}$$L^{-1}$, 10~20% individuals succeed adults while low emergence rates were observed surplus 30 $mu extrm{g}$$L^{-1}$. Death larvae appeared a various day along the concentration. We observed the converged day: control, 10 $mu extrm{g}$$L^{-1}$, 30 $mu extrm{g}$$L^{-1}$ and 60~100 $mu extrm{g}$$L^{-1}$ were day 4 to day 18, day 13 to day 16, day 9 to day 17 and day 9 to day 15, respectively. Therefore we concerned a tendency that exposure concentration was high, death period was short. Also, due to molting hormone disruption, development of midge was postponed relatively low concentration such as 10 $mu extrm{g}$$L^{-1}$. The converged days of pupa stage revealed control, 10 $mu extrm{g}$$L^{-1}$, 30 $mu extrm{g}$$L^{-1}$ and 60~100$mu extrm{g}$$L^{-1}$ were day 11~15, day 16~20, day 9~15 and day 5~9, respectively. About 10% individuals grow up the pupa-stage in 60~100 $mu extrm{g}$$L^{-1}$ condition. Sex ratio of the emerged adults was not different in this study. Death pupae frequently appeared in day 13~16 in control, day 6~23 in 10 $mu extrm{g}$$L^{-1}$, day 13~16 in 30 $mu extrm{g}$$L^{-1}$ and day 6~16 in 60~100 $mu extrm{g}$$L^{-1}$.
