We investigated the effects of molting-hormone insecticide tebufenozide on D7 (the day of hatching from egg) larvae of the midge Chironomus riparius in growth developments. D7 instar larvae were exposed test concentrations were chosen control, 10${mu}g ;L^{-1}$, 30${mu}g ;L^{-1}$, 60${mu}g ;L^{-1}$ and 100${mu}g ;L^{-1}$ of tebufenozide. In general, dead larvae showed 16% on the next day after insecticide treatments (D12), and observed 44% from D12 to D16 in this exposed days. Dead larvae of C. riparius was abruptly increased on D12 and also continuously increased along the days in 10${mu}g ;L^{-1}$ treatments. The converged day was from D12 to D16 at move 30${mu}g ;L^{-1}$ treatments in this study. Therefore, dead larvae obviously increased along these concentrations of tebufenozide. In control condition,78% of the test individuals have grown the pupae. But the larvae have developed the pupa stage from 5% to 17% of the test organism in 10${mu}g ;L^{-1}$ and 30${mu}g ;L^{-1}$ treatments. And 75% of the test individuals was arrived the adult through the molting process in control condition. While the other condition was rarely observed the adult. Usually, the emerged period of the test individuals was gathered the D26-D29 in control. The dead pupa showed from D19 to D20 in 30${mu}g ;L^{-1}$ treatments, D32 in control and D33 in 10${mu}g ;L^{-1}$ treatments. The observed periods of dead pupa were D32-D34 in control and D33-D37 in 10${mu}g ;L^{-1}$ treatments. Consequently, due to molting hormone disruption, development of midge was postponed relatively low concentration such as 10 treatments of tebufenozide.
