Abstract：A cell line of cabbage looper( Trichoplusia ni ) BT1 TN 5B1 was used to select resistant coloy to B.t. preparation. The results showed that the resistance was developed very slowly, with only 3 folds increase during 23 generations. After 23 generations selection, the resistant level was up to 10 folds ruptly, and fluctuated between 8 and 10 fold. The difference of the exterase isozymes between the selected colony (R5B1) and normal colony (SB51) was examined. The result showed that there were three bands that were the same in the R5B1 and S5B1 samples, and both colonies had two special bands, respectively. The consequence showed that there were possibly some changes in the physiology and metalism of the selected 5B1 cells.
